Line-side connection

The LOGO!Power power supplies are power packs according. to safety class II (without
protective conductor or equivalent without PE). LOGO!Power are designed for connection to
a 1-phase AC supply network (TN or TT system according to VDE 0100 T 300 / IEC 364-3)
with rated voltage 1-phase 100-240 VAC, 50/60 Hz or to a power supply with 110-300 VDC.
Figure 5-1
The line supply is connected using terminal L1 and N (see Figure 5-1 Line connection
(Page 23)), 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 must not be used as the only
protective measure against indirect contact; this applies to the entire supply system that is
protected by the residual current operated circuit-breaker.
