WARNING
Electric shock and danger to life due to other energy sources
Touching live components can result in death or serious injury.
• Only work on electrical equipment if you are appropriately qualified.
• Always observe the country-specific safety rules for all work.
Generally, the following steps apply when establishing safety:
1. Prepare for disconnection. Notify all those who will be affected by the procedure.
2. Isolate the drive system from the power supply and take measures to prevent it being
switched back on again.
3. Wait until the discharge time specified on the warning labels has elapsed.
4. Check that there is no voltage between any of the power connections, and between any
of the power connections and the protective conductor connection.
5. Check that every auxiliary circuit is de-energized.
6. Ensure that the motors cannot move.
7. Identify all other dangerous energy sources, e.g. compressed air, hydraulic systems or
water. Switch the energy sources to a safe state.
8. Check that the correct drive system is completely locked.
After you have completed the work, restore the operational readiness by following the
above steps in the reverse order.
WARNING
Electric shock due to connection to an unsuitable power supply
When equipment is connected to an unsuitable power supply, exposed components may
carry a hazardous voltage that might result in serious injury or death.
• Only use power supplies that provide SELV (Safety Extra Low Voltage) or PELV
(Protective Extra Low Voltage) output voltages for all connections and terminals of the
electronics modules.

Safety information
WARNING
Electric shock due to equipment damage
Improper handling may cause damage to equipment. For damaged devices, hazardous
voltages can be present at the enclosure or at exposed components; if touched, this can
result in death or severe injury.
• Ensure compliance with the limit values specified in the technical data during transport,
storage and operation.
• Do not use any damaged devices.
WARNING
Electric shock due to unconnected cable shield
Hazardous touch voltages can occur through capacitive cross-coupling due to unconnected
cable shields.
• Connect cable shields and unused conductors of power cables (e.g. brake conductors)
at least on one side to the grounded housing potential.
WARNING
Electric shock if there is no ground connection
For missing or incorrectly implemented protective conductor connection for devices with
protection class I, high voltages can be present at open, exposed parts, which when
touched, can result in death or severe injury.
• Ground the device in compliance with the applicable regulations.
WARNING
Arcing when a plug connection is opened during operation
Opening a plug connection when a system is in operation can result in arcing that may
cause serious injury or death.
• Only open plug connections when the equipment is in a voltage-free state, unless it has
been explicitly stated that they can be opened in operation.
NOTICE
Property damage due to loose power connections
Insufficient tightening torques or vibration can result in loose power connections. This can
result in damage due to fire, device defects or malfunctions.
• Tighten all power connections to the prescribed torque.
• Check all power connections at regular intervals, particularly after equipment has been
transported.

Safety information
WARNING
Spread of fire from built-in devices
In the event of fire outbreak, the enclosures of built-in devices cannot prevent the escape of
fire and smoke. This can result in serious personal injury or property damage.
• Install built-in units in a suitable metal cabinet in such a way that personnel are
protected against fire and smoke, or take other appropriate measures to protect
personnel.
• Ensure that smoke can only escape via controlled and monitored paths.
WARNING
Failure of pacemakers or implant malfunctions due to electromagnetic fields
Electromagnetic fields (EMF) are generated by the operation of electrical power equipment,
such as transformers, converters, or motors. People with pacemakers or implants in the
immediate vicinity of this equipment are at particular risk.
• If you have a heart pacemaker or implant, maintain a minimum distance of 2 m from
electrical power equipment.
WARNING
Unexpected movement of machines caused by radio devices or mobile phones
When radio devices or mobile phones with a transmission power > 1 W are used in the
immediate vicinity of components, they may cause the equipment to malfunction.
Malfunctions may impair the functional safety of machines and can therefore put people in
danger or lead to property damage.
• If you come closer than around 2 m to such components, switch off any radio devices or
mobile phones.
• Use the "SIEMENS Industry Online Support App" only on equipment that has already
been switched off.
WARNING
Motor fire in the event of insulation overload
There is a greater load on the motor insulation as result of a ground fault in an IT system. If
the insulation fails, it is possible that death or severe injury can occur as a result of smoke
and fire.
• Use a monitoring device that signals an insulation fault.
• Correct the fault as quickly as possible so the motor insulation is not overloaded.

Safety information
WARNING
Fire due to inadequate ventilation clearances
Inadequate ventilation clearances can cause overheating of components with subsequent
fire and smoke. This can cause severe injury or even death. This can also result in
increased downtime and reduced service lives for devices/systems.
• Ensure compliance with the specified minimum clearance as ventilation clearance for
the respective component.
WARNING
Unrecognized dangers due to missing or illegible warning labels
Dangers might not be recognized if warning labels are missing or illegible. Unrecognized
dangers may cause accidents resulting in serious injury or death.
• Check that the warning labels are complete based on the documentation.
• Attach any missing warning labels to the components, where necessary in the national
language.
• Replace illegible warning labels.
NOTICE
Device damage caused by incorrect voltage/insulation tests
Incorrect voltage/insulation tests can damage the device.
• Before carrying out a voltage/insulation check of the system/machine, disconnect the
devices as all converters and motors have been subject to a high-voltage test by the
manufacturer, and therefore it is not necessary to perform an additional test within the
system/machine.
WARNING
Unexpected movement of machines caused by inactive safety functions
Inactive or non-adapted safety functions can trigger unexpected machine movements that
may result in serious injury or death.
• Observe the information in the appropriate product documentation before
commissioning.
• Carry out a safety inspection for functions relevant to safety on the entire system,
including all safety-related components.
• Ensure that the safety functions used in your drives and automation tasks are adjusted
and activated through appropriate parameterizing.

1.4 Residual risks of power drive systems

When assessing the machine or system-related risk in accordance with the respective local
regulations (e.g. EC Machinery Directive), the machine manufacturer or system installer
must take into account the following residual risks emanating from the control and drive
components of a drive system:
1. Unintentional movements of the driven machine or system components during
commissioning, operation, maintenance, and repairs caused by, for example:
– Hardware and/or software errors in the sensors, control system, actuators and
connection system
– Response times of the controller and drive
– Operation and/or environmental conditions outside the specifications
– Condensation/conductive pollution
– Parameterization, programming, cabling, and installation errors
– Use of wireless devices/mobile phones in the immediate vicinity of electronic
components
– External influences/damage
– X-ray, ionizing radiation and cosmic radiation
2. Unusually high temperatures, including open flames, as well as the emission of light,
noise, particles, gases, etc., can occur inside and outside the components under fault
conditions caused by, for example:
– Component malfunctions
– Software errors
3. Hazardous shock voltages caused by, for example:
– Component malfunctions
– Influence of electrostatic charging
– Induction of voltages in moving motors
– Condensation/conductive pollution
4. Electrical, magnetic and electromagnetic fields generated in operation that can pose a
risk to people with a pacemaker, implants or metal replacement joints, etc., if they are too
close
5. Release of environmental pollutants or emissions as a result of improper operation of the
system and/or failure to dispose of components safely and correctly
6. Influence of network-connected communication systems, e.g. ripple-control transmitters
or data communication via the network.
For more information about residual risks of the components in a drive system, see the
relevant sections in the technical user documentation.

General 2
As a result of the modular concept, each of the individual combinations cannot be described.
Instead, fundamentals and generally applicable rules are explained, which when applied,
allow special device combinations to be mechanically configured that are electromagnetically
compatible.
As a result of their design, the components are intended for installation in housings and
cabinets. These housings are generally steel cabinets or control boxes, which guarantee
protection against direct contact and other environmental effects. They are part of an overall
EMC concept.
2.1 Safety information
WARNING
Not observing fundamental safety instructions and residual risks
The non-observance of the fundamental safety instructions and residual risks stated in
Chapter 1 can result in accidents with severe injuries or death.
• Adhere to the fundamental safety instructions.
• When assessing the risk, take into account residual risks.
WARNING
Danger of injury caused by foreign objects in the device
Parts (e.g.: drilling chips, end sleeves) falling into the device can cause short-circuits and
damage the insulation. This can lead to serious injuries (arcing, bangs, pieces flying out of
the equipment).
• Only perform installation and other work when the devices are current-free.
• Cover the ventilation slots during the installation of the cabinet and remove the cover
before switching on.
NOTICE
Limitation of overvoltages
On systems with a grounded phase conductor and a line voltage >600 VAC, line-side
components should be installed to limit overvoltages to overvoltage category II in
accordance with IEC 61800-5-1.

General
2.2 Directives
Note
Protection against the spread of fire
The converter may be operated only in closed housings or in higher-level control cabinets
with protective covers that are closed, and when all of the protective devices are used.
Converters of the Open Type/IP20 degree of protection must be installed in a metal control
cabinet or protected by another equivalent measure such that fire cannot spread and
emissions outside of the control cabinet are prevented.
Note
Protection against condensation and electrically conductive contamination
To ensure the functional safety and safety functions of Safety Integrated, protect the
converter, e.g. by installing it in a control cabinet with degree of protection IP54 according to
IEC 60529 or Type 12 according to NEMA 250. Further measures may be necessary for
particularly critical operating conditions.
If condensation and conductive pollution can be excluded at the installation site, a lower
degree of cabinet protection may be permitted.
2.2 Directives
The switchgear cabinet must satisfy the following EC Directives in the European Economic

Basic information about EMC 3
3.1 Introduction to EMC
What is meant by EMC?

Electromagnetic compatibility (EMC) describes the capability of an electrical device to
function satisfactorily in an electromagnetic environment without itself causing interference
unacceptable for other devices in the environment.
EMC therefore represents a quality feature for the
● Internal noise immunity: Resistance to internal electrical disturbances
● External noise immunity: resistance against external electromagnetic disturbances
● Noise emission level: environmental effects caused by electromagnetic emissions
To ensure that the cabinet unit functions satisfactorily in the system, the environment subject
to interference must not be neglected. For this reason, special requirements exist regarding
the structure and the EMC of the system.
Operational reliability and noise immunity

In order to achieve the greatest possible operational reliability and immunity to noise of a
complete system (converter, automation, drive machines etc.), measures must be taken by
the converter manufacturer and the user. Only when all these measures are fulfilled can the
faultless functioning of the inverter be guaranteed and the specified legal requirements
(2014/30/EU) be met.

Basic information about EMC
Noise emissions
Product standard EN 61800–3 describes the EMC requirements placed on "Variable-speed
drive systems". It specifies requirements for inverters with operating voltages of less than
1000 V. Different environments and categories are defined depending on where the drive
system is installed.
Figure 3-1 Definition of the first and second environments
Figure 3-2 Definition of categories C1 to C4
Table 3- 1 Definition of the first and second environments
Definition of the first and second environments

First environment Residential buildings or locations at which the drive system is connected to
a public low-voltage supply network without a transformer.
Second environment Industrial locations supplied by a medium-voltage network via a separate
transformer.

Table 3- 2 Definition of categories C1 to C4
Definition of categories C1 to C4
Category C1 Rated voltage <1000 V; unrestricted use in the first environment.
Category C2 Rated voltage for stationary drive systems <1000 V; for use in the second
environment. For use in the first environment only when sold and installed
by skilled personnel.
Category C3 Rated voltage <1000 V; use in the second environment only.
Category C4 Rated voltage ≥1000 V or for rated currents ≥ 400 A in complex systems in
the second environment.


EMC-compliant design and control cabinet

EMC-compliant design and control cabinet configuration

Cabinet air conditioning 5
5.1 General
The minimum dimensions listed below for ventilation clearances must be observed. No other
components or cables must be located in these areas.
NOTICE
Device failure caused by overloading of devices and components
If the guidelines for installing SINAMICS G130 equipment are not observed, this can
significantly reduce the service life of the components and result in premature device and
component failure.
• Observe the guidelines for installing the devices and components.
You must take into account the following specifications when using SINAMICS G130:
● Ventilation clearance
● Wiring and cabling
● Air guidance
Table 5- 1 Ventilation clearances for the components
Component Frame size Clearance (front) Clearance (above) Clearance (below)

Note
Notes on the dimensions
The dimensions refer to the outer edges of the devices.
A dimension drawing is available in the Operating Instructions.

5.2 Ventilation
5.2 Ventilation
The SINAMICS G130 devices are forced-ventilated by means of integrated fans. To ensure
an adequate air supply, suitable openings for the inlet air (e.g. ventilation slots in the cabinet
door) and discharged air (e.g. by means of a hood) must be provided.
The cooling air must flow through the components vertically from bottom (cooler region) to
top (region heated by operation).
You must ensure that the air is flowing in the right direction. You must also ensure that the
warm air can escape at the top. The ventilation clearances specified in the table "Ventilation
clearances for the components" in the previous section must be observed.
Note
Cables must not be routed directly on the components. The ventilation slots must not be
covered.
Cold air must not be allowed to blow directly onto electronic equipment.
NOTICE
Device failure due to condensation as a result of unsuitable air guidance and cooling
Unsuitable air guidance and cooling equipment can cause condensation, which can result
in device failure.
• Choose air guidance measures, as well as the arrangement of and settings for the
cooling equipment in such a way as to prevent condensation even with the highest
relative humidity.
• If required, install cabinet enclosure heating.

5.2 Ventilation

5.2 Ventilation
Figure 5-2 Air guidance for Power Module, frame size HX, JX
Devices must not be operated in an "air short-circuit", since this can damage equipment or
cause it to fail.
The fan suction causes negative pressure to build up at the ventilation openings in the
cabinet doors. The pressure is dependent on the volume flow rate and the hydraulic cross-
section of the openings.
The air, which blows out of the top of the device, accumulates under the top cover/hood,
resulting in overpressure.
The difference between the overpressure at the top of the cabinet and the negative pressure
at the bottom creates a flow of air (air short-circuit). This can vary in strength depending on
the cross-section of the door and cover openings, as well as the volume flow rate of the air.
Due to the flow of air within the cabinet, the device fan draws in pre-heated air. This heats up
the components considerably and the ventilator does not function effectively.

5.2 Ventilation
NOTICE
Device failure due to air short-circuit in the control cabinet
Unsuitable air guidance can cause an air short-circuit, which can result in overheating in the
control cabinet and device failure.
• Install suitable barriers in the control cabinet in order to prevent an air short-circuit from
occurring.
Barriers must be installed in such a way that no air can flow along the outer sides on the top
and bottom of the devices. In particular, air must be prevented from flowing from the top
(warm discharged air) to the bottom (cold cooling air). Suitable plates can be used as
barriers and must extend to the side panels or cabinet doors. They must be set up in such a
way that the outgoing air current is not forced into the cabinet cross-beams but is instead
diverted around them. Barriers must be in place for all degrees of protection higher than
IP20.
The cabinets adjacent to the converter cabinets must also be taken into account when
barriers are installed.
To ensure sufficient ventilation for the devices, the opening cross-sections (minimum values)
specified in the following table must be observed.
The specified opening cross-sections comprise several small openings. To ensure that
pressure loss is kept to a minimum and that the flow resistance does not become too great
at these mesh-type openings, the cross sectional area of each opening must be around at
least 190 mm² (e.g. 7.5 mm x 25 mm or 9.5 mm x 20 mm).
To ensure that the devices operate continuously, suitable measures must be taken to
prevent the ingress of dirt and dust. Wire lattices (wire fabric DIN 4189-St-vzk-1x0.28) or
filter mats (min. filter class G2) must be used for this purpose. The choice of filter mats
depends on the required degree of protection and the ambient conditions. If cabinets are
installed in an environment containing fine dust particles or oil vapors, micro-filter mats must
be used to prevent the devices from becoming contaminated.
If dirt filters are used, the specified opening cross-sections and the filter areas must be
adjusted upwards.
NOTICE
Device failure due to overheating as a result of contaminated dirt filters
Contaminated filter mats cause the device to overheat and fail.
• If dirt filters are used, observe the specified replacement intervals.
If the filter mats are heavily contaminated, the volume of air drawn is reduced due to the
increased flow resistance. This can cause the fans integrated in the devices to overload, or it
could cause the devices themselves to overheat and become damaged.
The opening cross-sections specified in the table refer in each case to one device. If more
than one device is installed in a cabinet, the opening cross-section increases accordingly. If
the required openings cannot be made in the cabinet, the devices must be distributed across
several cabinets, which are separated from each other by means of partitions.

5.2 Ventilation
The warm air must be discharged via the top cover/hood or via side openings in the cabinet
at the level of the top of the device. The size of the opening cross-section must also be taken
into account here.
With degrees of protection higher than IP20 and if a hood is used, it may be necessary to
use an "active" hood. An "active" hood contains fans that blow the air current forwards. The
hood is closed, with the exception of the air outlet point.
If you choose an "active" hood, you must ensure that the fans are sufficiently powerful to
prevent air from accumulating in the cabinet. If air accumulates, the cooling capacity is
reduced. This can overheat and destroy the devices. The air capacity of the fans should at
least be equivalent to the device fan data.
