Line-side connection

The LOGO!Power power supplies are power packs acc. 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 in accordance with VDE 0100 T 300 / IEC 364-3) with

rated voltage 1-phase 100-240 V AC, 50/60 Hz or to a power supply with 110-300 V DC .

Figure 4-1 Line connection

The connection of power supply network is made via the terminals L1 and N (see Fig. 4-1)

and must be established in accordance with 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 residual current circuit-breaker 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.

Line-side protection (IEC 898) to be implemented upstream:

● Circuit breaker characteristic C, from 10 A or

● circuit breaker characteristic B, from 16 A

Other country-specific regulations may have to be observed when installing the device.
