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 power supplies are designed for connection to a 1-phase AC line supply
(TN-, TT or IT line supply according to IEC 60364-1 with rated voltage 120 - 230 V AC,
50 - 60 Hz or a DC power supply with 120 V - 240 V DC (3.7 A/24 V, 5 A/24 V, 7 A/12 V) or
110 V - 240 V DC (10 A/24 V, 12 A/12 V)
Figure 5-1 Line-side connection
The line supply is connected using terminal L1, N (L2) and PE (see Figure 5-1 Line-side
connection (Page 39)), 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.
