WARNING
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 modular power supply is designed for connection to a 1-phase/2-phase AC line
supply (TN, TT or IT system according to VDE 0100 T 300 / IEC 364-3) with a rated voltage
of 120-230/230-500 VAC or 120/230 VAC, 50/60 Hz.
Figure 5-1
Line connection (example, 6EP1334-3BA10 and 6EP1337-3BA00)
The line supply is connected using terminal L1, L2(N) and PE (see Figure 5-1 Line
connection (example, 6EP1334-3BA10 and 6EP1337-3BA00) (Page 33)), and must be
implemented according to IEC 60364 and EN 50178 .
The switch must be changed over for operation with 120 V input voltage for 6EP1333-3BA10
and 6EP1334-3BA10 (see Figure 2-8 Voltage selector switch (example, 6EP1334-3BA10)
(Page 15)). A wire jumper must be connected to the input terminal Jump 120 V AC for
6EP1336-3BA00 and 6EP1337-3BA00 (see Figure 2-9 Wire jumper (example, 6EP1437-
3BA00) (Page 15)).
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. If the power supply is operated
