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
SITOP PSU6200 supplies are designed for connection to a 3-phase AC line supply (TN, TT,
IT or "corner grounded" line supply according to IEC 60364-1) with rated voltages
400 - 500 V AC (IT or "corner grounded" line supply 400 V), 50 - 60 Hz.
Figure 5-1
The line supply is connected using terminals L1, L2, L3 and PE (see Line-side connection
(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.
