SITOP PSU100C 24 Operating Instructions, 06.2013, C98130-A7599-A1-2-7629 Installation 5.2 Output-side connection 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 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). + DC SITOP - SITOP + - 7HUPLQDOEORFN SITOP AC /2$' DC DC - - + AC DC &255(&7 Figure 9-1 /2$' SITOP + AC + AC - ,1&255(&7 Parallel connection Note The power-up of two SITOP PSU100C (2 x Ia,rated) power supplies is only permissible with the basic rated load (Ia, rated). SITOP PSU100C Operating Instructions, 06.2013, C98130-A7599-A1-2-7629 47 Applications 9.1 Parallel connection to increase the power rating 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. SITOP PSU100C 48 Operating Instructions, 06.2013, C98130-A7599-A1-2-7629 Applications 9.2 Parallel connection for redundancy 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)).

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.
