The protective conductor of the line supply must be connected at the PE terminal.
Other country-specific regulations may have to be observed when installing the device.
Note
For operation on a DC power system (DC), the plus pole (+) must be connected to L1 and
the minus pole (–) to N.

Operating Instructions, 06.2013, C98130-A7599-A1-2-7629 25
5.2 Output-side connection
The SITOP PSU100C power supplies provide an isolated (= non-grounded) SELV (Safety
Extra Low Voltage) output voltage. The output of the power supplies 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 (refer to Chapter Technical data (Page 27)).
Figure 5-2 Connecting the output voltage (example 6EP1332-5BA10)
The output voltage is connected via the + and - terminals at the output of the power supply
(see Figure 5-2 Connecting the output voltage (example 6EP1332-5BA10) (Page 25)). Make
sure 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), 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 using a minimum 1.5 mm2 conductor cross-section.

The device supplies a constant output voltage until the current limit is reached. In the event
of an overload, the output current and the output voltage are reduced. When the output
voltage falls below approx. 9 V (12 V versions) and 15 V (24 V versions), the device switches
off, and automatically restarts. This response is repeated as long as the overload condition is
present.

Applications 9
9.1 Parallel connection to increase the power rating
To increase the power rating, two identical power supplies SITOP PSU100C, with the
exception of 6EP1331-5BA00 and 6EP1332-5BA20, can be directly connected with one
another galvanically.
The following must be observed:
● The output voltages of the power supplies to be connected in parallel may differ by a
maximum of 0.2 % under no load conditions.
When required, the output voltages must be adjusted with the potentiometer.
To do this, the "–" terminals should be connected, and under no-load conditions, the
voltage difference measured between the "+" terminals that have not been connected
together. This voltage difference must not exceed 0.2%.
● 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 network junction (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).

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 reverse currents in the event of a secondary device fault. For this
purpose, a suitable protective circuit (e.g. decoupling diode
or DC-compatible miniature circuit-breaker) must be installed between each "+" terminal of
the power supply and the common connection point.
Applications
9.2 Parallel connection for redundancy
SITOP PSU100C
Operating Instructions, 06.2013, C98130-A7599-A1-2-7629 49
9.2 Parallel connection for redundancy
Connecting several SITOP PSU100C power supplies in parallel for redundancy purposes is
required if especially high demands are placed on the availability of a reliable 24 V power
supply.
Using the SITOP PSE202U redundancy module, two 24 V power supplies of the same type
can be decoupled (Figure 9-2 Redundant configuration (Page 49)). 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.
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 protected separately on the line-side and, if possible, be connected to different
power supply networks.
Note
The SITOP PSE202U NEC Class 2 (6EP1962-2BA00) redundancy module must be used to
create a redundant circuit configuration according to NEC Class 2 (Figure 9-3 Parallel
connection with redundancy module for NEC Class 2 (Page 50)).

9.3 Series connection for increased voltage
SITOP PSU100C
Operating Instructions, 06.2013, C98130-A7599-A1-2-7629 51
9.3 Series connection for increased voltage
To achieve an output voltage of 48 V DC, two SITOP PSU100C 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 V DC according to EN 60950 cannot be guaranteed in the case of a
fault.
