WARNING
Hazard due to electric shock
Before installation or maintenance work can begin, the system's main switch must be
switched off and measures taken to prevent it being switched on again. If this instruction is
not observed, touching live parts can result in death or serious injury.

5.1 Line-side connection

The SITOP PSU8200 3ph power supply is designed for connection to a 3-phase AC line
supply with a rated voltage of 400-500 V AC, 50/60 Hz.

Figure 5-1 Line supply connection

The line supply is connected using terminals L1, L2, L3 and PE (see Figure 5-1 Line supply
connection (Page 25)), and must be implemented according to IEC 60364 and EN 50178 .
A protective device (miniature circuit breaker or circuit breaker) and a disconnection unit for
the power supply must be provided. A ground-fault circuit interrupter is not permissible
against indirect contact as the only protective measure. This applies for the complete line
supply protected by the ground-fault circuit interrupter.

 Installation
5.2 Output-side connection

5.2 Output-side connection

At its output, the SITOP PSU8200 3ph power supply provides an isolated (= non-grounded)
SELV output voltage (Safety Extra Low Voltage). The output of the power supply is no-load,
overload and short-circuit proof. If an overload occurs, the electronic current limiting function
limits the output current to a maximum value (see Section Technical data (Page 29)).

Figure 5-2 Output connection

The output voltage is connected via the "+" and "–" terminals at the output of the power
supply (see Figure 5-2 Output connection (Page 27)). Ensure that the output cables are
dimensioned correctly for the maximum output current rms value and fused accordingly.

Note
If the safety concept of the plant or system specifies that the DC output circuit should be
grounded ((PELV, Protected Extra Low Voltage), then it is permissible that the output voltage
of the SITOP power supply is grounded. In this case, ideally, the grounding at the output
should be directly connected from terminal "-" of the power supply to a suitable connection
point of the protective conductor system (PE) of the plant or system.

Applications 9
9.1 Parallel connection to increase power rating
To increase the power rating, SITOP PSU8200 power supplies of the same type can be
directly connected in parallel.
The following must be observed:
● The cables connected to each power supply at terminals "+" and "-" must have identical
lengths and the same cable cross-sections (or the same impedance) up to a common
external connection point (terminal strip) if possible.
● The power supplies connected in parallel must be switched on simultaneously with a
common switch in the line feeder cable (e.g. with the main switch available in control
cabinets).
● The output voltages measured in no-load operation for the power supplies that are not yet
connected in parallel should not deviate more than a maximum of 50 mV. This usually
corresponds to the factory setting. If the output voltage is changed, you should connect
the "-" terminals and then, in no-load operation, measure the voltage difference between
the "+" terminals that have not yet been connected. The voltage difference should not
exceed 50 mV.
● Switch selector switch "A" (see Figure 2-6 Selector switch (Page 14)) to "Parallel
operation".

NOTICE
Protective circuit for the parallel connection of more than two power supplies
When connecting more than two power supplies in parallel, additional measures must be
taken to prevent high backward feeding currents in the event of a secondary device
fault. For this purpose, a suitable protective circuit (e.g. decoupling diode
or DC-conform circuit breaker) must be installed between each "+" terminal of the power
supply and the common connection point.

9.2 Parallel connection for redundancy

9.2 Parallel connection for redundancy

Connecting several SITOP PSU8200 power supplies in parallel for redundancy purposes is
required if especially high demands are placed regarding the availability of a reliable 24 V
power supply.
Using the SITOP PSE202U redundancy module, two power supplies of the same type up to
20 A can be decoupled (Figure 9-2 Redundant configuration with two power supplies and
SITOP PSE202U redundancy module (Page 47)). When one of the devices fails, then the
other automatically takes over the power supply. If one of the power supplies fails, then this
is signaled using an LED on the redundancy module as well as an isolated relay contact.
For higher output current, each power supply must be connected to a redundancy module
(Figure 9-3 Redundant configuration with two power supplies and two SITOP PSE202U
redundancy modules (Page 47)). When dimensioning the system, it must be ensured that
n+1 redundant connected power supplies can handle the total power requirement of the
remaining n power supplies.

Note
For a high reliability of the supply, it is recommended that the redundant switched power
supplies are fused separately on the line-side and, if possible, be connected to different
power supply networks.

9.3 Series connection for increased voltage

9.3 Series connection for increased voltage

To achieve an output voltage of 48 V DC, two 24 V SITOP PSU8200 power supplies of the
same type can be connected in series. In this case, connect the "-" terminal of the first power
supply to the "+" terminal of the second power supply. The "+" terminal of the first power
supply and the "-" terminal of the second power supply are routed to the load.
Depending on the grounding point of the secondary output voltages, voltages of +48 V,
±24 V or -48 V can be realized.
In the case of an asymmetric load distribution, it is not possible to guarantee correct
functionality.

WARNING
SELV is not guaranteed in the case of a fault
When connecting two power supplies in series, the continuous, permissible SELV voltage
of a maximum of 60 VDC according to EN 60950 cannot be guaranteed in the case of a
fault.

Applications
9.4 Overload protection in the 24 V output circuit

9.4 Overload protection in the 24 V output circuit

If an overload occurs, the electronic current limiting function limits the SITOP PSU8200
output current to a maximum value (see Section Technical data (Page 29)). The output
cables are protected against a thermal overload if they are dimensioned corresponding to
the maximum rms output current, or protected using additional components (for example,
miniature circuit breaker, fuses).
However, a load circuit that fails as a result of overload, for instance, should frequently be
reliably and quickly identified and specifically switched off before the power supply goes into
current-limiting mode (in current-limiting mode, the supply voltage would also be reduced for
all of the remaining 24 V loads).
The SITOP PSE200U selectivity module with 4 outputs (versions with adjustable output
current range for each output from 0.5-3 A and 3-10 A) is available for this purpose; this
monitors the 24 V branches for overload and short-circuit (Figure 9-5 Electronic protection of
24 V consumers with the SITOP PSE200U selectivity module (Page 50)). Brief current
peaks, e.g. as a result of a high inrush current, are permitted, and branches with a longer
overload are switched into a no-current condition. This is also ensured for cables in a high-
ohmic condition and for short-circuits that slowly develop over time.
When an output fails, the fault is signaled using a group signal contact or as a single channel
signal, and the branch of the module involved is displayed using an LED.
For versions with single-channel signaling, function blocks for evaluation purposes are
available at no charge for SIMATIC S7-1200/1500/300/400, for STEP 7 and TIA Portal as
well as for SIMOTION CPUs and SIMOTION SCOUT.

9.5 Protection against short-time voltage dips

9.5 Protection against short-time voltage dips

In the case of a drop in the line-side supply voltage, the SITOP PSU8200 power supply can
still maintain the output voltage for a short time in the millisecond range (see section
Technical data (Page 29)).
For line supplies that manifest frequent brief voltage dips, in order to increase the power
supply reliability, it may make sense to increase the line buffering time in the device using an
additional SITOP PSE201U buffer module.
The SITOP PSE201U buffer module, based on electrolytic capacitors, is connected in
parallel to the 24 V power supply output (Figure 9-6 Buffering brief power failures using the
SITOP PSE201U buffer module (Page 51)). The buffer time is 200 ms at 40 A up to 1.6 s for
a load current of 5 A. This time can be increased a multiple number of times by connecting

9.6 Protecting against longer power failures

Sudden and longer failures of the line supply voltage can result in undefined states and
significant danger as a result of the associated failure of the plant or system control. The
SITOP power supply product portfolio includes various DC-UPS solutions to prevent the
failure of the 24 V power supply voltage.
Power supply failures up into the minutes range can be buffered using the maintenance-free
SITOP UPS500 DC-UPS modules based on capacitors (Figure 9-7 24 V buffering to allow
the saving of process data and controlled shutdown of PCs (Page 52)).

Figure 9-7 24 V buffering to allow the saving of process data and controlled shutdown of PCs

Using the free-of-charge SITOP DC-UPS software tool, DC-UPS systems can be simply
integrated into PC-based automation solutions. This supports further processing of the status
signals and safely running down the PC.

 Applications
9.6 Protecting against longer power failures

Using DC UPS SITOP UPS1600 and SITOP UPS1100 battery modules, buffer times in the
range of hours can be implemented. Intelligent battery management using Energy Storage
Link automatically detects the UPS1100 energy storage device, and ensures optimum
temperature-controlled charging and continuous monitoring. The UPS1600 can be flexibly
integrated into the widest range of automation applications with its digital inputs/outputs as
well as optional USB interface or Ethernet/PROFINET port.

sensor measured values and position values

For open, PC-based automation systems, configuration and monitoring is realized using the
SITOP UPS Manager PC software, which is available at no charge. This allows PC
responses to the operating states of the DC UPS to be freely selected – and offers
comprehensive diagnostic functions.
For TIA-based automation systems, the UPS1600 is engineered using the TIA Portal.
Special function blocks for SIMATIC S7-300/400/1200 and S7-1500 – available at no charge
– make it easy to integrate operating and diagnostics information into STEP 7 user
programs. Preconfigured UPS faceplates for WinCC visualization can be downloaded at no
charge.
