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 PSU300S power supply is designed for connection to a 3-phase AC line supply
(TN or TT system according to VDE 0100 T 300 / IEC 364-3) with a rated voltage of
3-phase 400 - 500 VAC, 50 - 60 Hz.
Figure 5-1
The line supply is connected using terminal L1, L2, L3 and PE (see Figure Line connection
(example: 6EP1436-2BA10) (Page 31)), 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.
