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 PSU8200/3800 3ph power supply is designed for connection to a 3-phase AC
line supply (TN-, TT or IT system according to IEC 60364-1) with a rated voltage of
400 - 500 V, 50 - 60 Hz.
Figure 5-1
The line supply is connected using terminals L1, L2, L3 and PE (see Figure 5-1 Line supply
connection (Page 49)), 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 applies for the complete line
supply protected by the ground-fault circuit interrupter.
