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
SIMATIC ET200SP PS power supplies are designed for connection to a 1-phase AC line
supply (TN or TT system according to IEC 60364-1) 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 supply
connection (Page 23)), and must be implemented according to IEC 60364 . 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.
