Safety Instructions

2. Safety Instructions
2.1 General instructions

Danger Electric Shock

KEB COMBIVERT units contain dangerous voltages which can cause death
or serious injury.
Care should be taken to ensure correct and safe operation to minimise risk
to personnel and equipment.

Attention Only Qualified Electro-Personnel

All work to installation and start-up as well as maintenance may only be done by qualified
personnel (IEC 364 and/or CENELEC HD 384 and IEC-Report 664 and note national safety
regulations). According to this manual qualified staff means those who are able to recognise
and judge the possible dangers based on their technical training and experience and those
with knowledge of the relevant standards and who are familiar with the field of power trans-
mission.

Attention Observe Standards

The inverter or servo drive must not be started until it is determined that the installation com-
plies with the Machine directive (note EN  60204) as well as the EMC-directive.
The COMBIVERT meets the requirements of the Low-Voltage Directive. The harmonized
standard of the series EN 61800‑5‑1 (VDE 0160) is used.
This is a product of limited availability in accordance with IEC 61800-3. This product may
cause radio interference in residential areas. In this case the operator may need to take cor-
responding measures.

2.2 Transport, storage and installation

The storage of the COMBIVERT must be done in the original packing. It is to be protected
against humidity and excessive cooling and thermal effect. A long-distance transport must be
carried out in the original packing. It is to be secured against impact influence. Observe the
marking on the final packing! After removing the final packing the COMBIVERT must be set
down on a stable base.

12
 Safety Instructions

Attention Protect Against Accidental Contact

The COMBIVERT must be protected against invalid loading. Components and covers must
not be bent or moved as this may affect insulation distances. The units contain electrostatic
sensitive devices which can be destroyed by inappropriate handling. For that reason the
contact of electronic components and contacts is to be avoided. The equipment must not be
switched on if it is damaged as it may no longer comply with mandatory standards.
Make sure that during installation there is enough minimum clearance and enough cooling.
Climatic conditions must be observed in accordance with the instruction manual.

Attention Hot surface

Heat sinks can reach temperatures, which can cause burns when touching. If
in case of structural measures a direct contact cannot be avoided, a warning
notice "hot surface" must be mounted at the machine.

2.3 Electrical connection

Danger Note capacitor discharge time

Before any installation and connection work, the system must be switched
off and secured.
Depending on the application the pitch inverter is supplied for emergency
operation via energy storage at the DC link also after switching off the mains
supply.
Discharge is to be determined by measurement of the voltage disconnection,
since discharge of the energy storage can take several days. Then the unit
can be worked on again.

Attention Secure isolation

The terminals of the control terminal strip are securely isolated in accordance with EN 61800-
5-1. With existing or newly wired circuits with safe isolation the person installing the units or
machines must ensure that the requirements of the standards are met.

13
Safety Instructions

Attention Voltage with respect to ground

Connection of the COMBIVERT is only permissible on symmetrical networks with a maxi-
mum line voltage (L1, L2, L3) with respect to earth (N/PE) of 305V. The units may be dam-
aged if this is not observed.

Attention Leakage currents > 3.5 mA

According to EN 61800-5-1 the requirement must be fulfilled that safety is maintained in
case of destruction or separation of the protective earth conductor. At COMBIVERT, leakage
currents >3.5 mA occur especially when using EMC filters.
For stationary connection
• use a cross-section of the protective earth conductor of min. 10 mm² (copper) or 16 mm²
(aluminum)
or
• an automatic disconnection of the mains in case of interruption of the protective earth
conductor shall be provided
or
• use an additional terminal for a second protective earth conductor with the cross-section
as the original protective earth conductor

Attention Insulation measurement

When doing an insulation measurement in accordance with VDE 0100 / Part 620, the power
semiconductor of the unit and existing radio interference filters must be disconnected be-
cause of the danger of destruction. This is permissible in compliance with the standard,
since all inverters are given a high voltage test in the end control at KEB in accordance with
EN 61800-5-1.

Attention Different earth potentials

Use an additional line for equipotential bonding for the connection of terminals to compo-
nents that have no potential isolated inputs / outputs.
Disregard can lead to malfunctions or defects.

14
 Safety Instructions

Attention Conditionally short-circuit proof

The COMBIVERT is conditionally short-circuit proof (EN 61800‑5‑1 / VDE 0160). After reset-
ting the internal protection devices, the function as directed is guaranteed. Exception:
Repeatedly occurring ground faults or short-cicuits at the output can lead to the devective
of the unit.
Repeatedly occurring ground faults at BT-, HB-, F2, RB+ or RB- can lead to the devective
of the unit.

Info RCD (Residual Current Operated Circuit-Breaker)

The intended application of P6 does not require the use of a RCD. Type "B" must be used if
a RCD is required for reasons of personal or system protection. For more information please
contact KEB!

15
EMC Instructions

2.4 EMC Instructions

COMBIVERT represent electrical equipment designed for use in industrial and commercial
units. The person installing / operating the machine / unit is obliged to prove the protective
measures demanded by the EMC directive. The prescribed ratings can usually be complied
with when using the radio interference voltage filters specified by KEB, and when observing
the following measures and installation guidelines.

2.5 EMC conform installation

The COMBIVERT is designed to be used in the second environment as defined in EN 61800-
3 (unit with its own supply transformer). Take additional measures when using it in the first
environment (residential and commercial area connected to public low-voltage mains)!

• Install the cabinet or system correctly.

• Ground the cabinet or the system earth star point with the shortest connection to mains
earth (avoid earth loops)
• To avoid coupled-in noise, separate supply lines, motor lines, control and data lines (low-
voltage level < 48V) and leave a space of at least 15 cm between them when installing.
• In order to maintain low-resistance high frequency connections, earthing and shielding, as
well as other metallic connections (e.g. mounting plate, installed units) must be in metal-
to-metal contact with the mounting plate, over as large an area as possible. Make ground
connections with a surface as large as possible (earthing strips).
• Only use shielded cable with copper or tin-plated braid, since steel braid is not suitable for
high frequency ranges. The screen must always be installed on the compensating rail and
fastened with clips or guided through the wall of the housing. Do not elongate the screen
end (pigtails) with individual conductors!
• If external interference suppression filters are used, then these must be installed as close
as possible to (<30cm from) the interference source and in metal-to-metal contact with the
mounting plate.
• Always equip inductive control elements (contactors, relays etc.) with suppressors such as
varistors, RC-elements or damping diodes.
• All connections must be kept as short as possible and as close as possible to the earth, as
free floating lines work as active and passive aerials.
• Keep connection cables straight (do not bundle). Install a non-assigned wire at one sides to
the protective earth conductor.
• The flow and return circuit must be twisted when the lines are not shielded, in order to
dampen common-mode noise.
• Further informations are found in the internet, see „www.keb.de“.

The technical data are designed for pitch motors. When using other motors, please contact KEB.

The use of a mains choke is recommended. If using functional safety of the P6 in the applica-
tion (safety run with PL d according to EN 13849) an input choke is necessary ( e.g. 13Z1B04-
1000…19Z1B04-1000).

KEB generally recommends the use of wire-end ferrules in industrial

Info environments.

• Press pusher by hand. Insert connecting wires into the respective hole, that no single
wires can be seen from the outside or bend outward.
A first resistance must be overcome when inserting. Release the pusher.
• Check that the connecting wire is fixed and can not be pulled-out. It is important to en-
sure that the connecting wire and not the insulation is clamped. The connecting wire can
also be inserted without pressing the pusher in case of cross-sections upto 1.00 mm².

observance may lead to damage the switching unit or at the terminals of the COMBIVERT P6.

4.2.6 Connection of an external braking resistor

The COMBIVERT P6 provides internal braking resistors as standard. If the COMBIVERT P6
included the option "for external braking resistor", the braking resistor must be connected
with shielded cable at RB+ und RB-. If the braking resistor isn't intrinsically safe, it must be
thermically monitored.

4.3.8 Diagnostic interface X6A

The socket X6A is a serial RS232/485 interface. It serves for the connection of the control
with a PC or other operating units via the protocol DIN66019II. The control unit has the node
address 0, the drive unit has the node address 1. Alternatively, this interface can be accessed
by the IEC control program as desired, thus providing many different protocol variants (library
"SysCom“).

The maximum cable length at X6A must not exceed 30 m.

4.3.9 Ethernet interface (X6B)

The standardized 10/100 base-T interface supports the protocols TCP/IP and UDP/IP. The
following ports have the functions:
The run-time system uses ports 1740-1743 for the connection to the outside. The parameters
of the firmware are available via port 8001. TCP or UDP is possible as protocol, at which
encapsulated DIN66019II data telegrams will be transferred (the control unit has the node
address 0, the drive unit has the node address 1). The file system can be read/written via port
8002 (only UDP) with KEB ftp-file transfer protocol (writing only with application password).
Furthermore access to other ports of this interface is possible via the IEC control program
(library "SysSocket").

Info Connection to programming system !

A correct adjustment is important for the programming system connection. The IP address
can be set by parameter Et01. The subnet mask is set by parameter Et11.
Default: IP-Address 192.168.0.100
Subnet mask 255.255.255.0
A power-on reset is required after changing!
The interface supports automatic polarity detection, AutoCrossover and automatic speed de-
tection, adjustable by parameter Et15.

Attention Protect P6 against unauthorized access !

Each user within a network can take access to the control with knowledge of the IP address.
The write access via port 8001 can be restricted by parameter et09.

5.3 Storage
The DC link of the KEB COMBIVERT is equipped with electrolytic capacitors. If electrolytic
capacitors are stored de-energized, the oxide film acting as dielectric medium reacts with
the acidic electrolyte and degrades itself slowly. This affects the dielectric strength and the
capacity.
If the capacitor starts running with rated voltage, it is tried to build the oxide film abrupt again.
This generates heat and gas and destroys the capacitor.
In order to avoid defectives, the KEB COMBIVERT must be commissioned depending on the
storage period according to the following table:
Storage period < 1 year
• Start-up without special measures
Storage period 1…2 years
• Operate inverter one hour without modulation
Storage period 2…3 years
• Remove all cables from the power circuit; Remove X2A and X2B.
• Connect variable transformer to inverter input
• Increase variable transformer slowly (>1 min) to indicated input voltage and remain at
least for the specified time.
Input voltage Duration
0…280 V 15 min
280…400 V 15 min
400…500 V 1 h
Storage period > 3 years
• Input voltages as before, however double the times per year. Eventually change capaci-
tors.
Table 5: Measures after long storage time
After performing this re-commissioning, the KEB COMBIVERT can be operated at rated con-
ditions, or it can be put back to another storage.

5.4 Maintenance
All work may be performed by qualified personnel only. Please observe the follwing safety
rules:
• Disconnect mains power supply and energy storage
• Prevent unintentional restart
• Await discharge time of the capacitors (5 minutes)
• Verify by measurement that the unit is free of voltage
In order to avoid premature ageing and avoidable malfunctions, the measures mentioned
below must be carried out in the appropriate cycle.

5.7 Certification
5.7.1 CE Marking
CE marked frequency inverter and servo drives were developed and manufactured to comply
with the regulations of the Low-Voltage Directive.
The inverter or servo drive must not be started until it is determined that the installation com-
plies with the Machine directive (note EN  60204) as well as the EMC-directive.
The frequency inverters and servo drives meet the requirements of the Low-Voltage Direc-
tive. The harmonized standards of the series EN 61800-5-1 in connection with EN 60439-1
and EN 60146 were used.
This is a product of limited availability in accordance with IEC 61800-3. This product may
cause radio interference in residential areas. In this case the operator may need to take cor-
responding measures.
