Installation
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 PSU100S power supply is designed for connection to a 1-phase AC line supply
(TN or TT system according to VDE 0100 T 300 / IEC 364-3) with a rated voltage of
120/230 V AC, 50/60 Hz.
Figure 5-1
The line supply is connected using terminals L1, N and PE (see Figure 5-1 Line connection
(examples 6EP1334-2BA20 and 6EP1336-2BA10) (Page 35)), 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 is true for the complete line supply protected by the ground-fault circuit
interrupter.
