Basic elements
Connecting direct current power supply modules from an alternating current network Non-insulated power supply modules TSX PSY 1610/3610 Connecting a single-rack PLC station with a ground-referenced network:
Q: General section switch, KM: Circuit contactor-breaker, (1): External shunt provided with the power supply module, (2): Insulating connector bar for finding grounding faults. In this case, it is necessary to switch off the supply in order to disconnect the network from the ground, (3): Optional use of a process power supply module (4): Protective fuse, (4 A, with time-delay) only necessary with the TSX PSY 3610 power supply module. The TSX PSY 1610 power supply module is fitted during manufacture with a protective fuse located under the module and in series on the 24V input (3.5 A, 5x20 time-delay fuse).
