Output-side connection
The LOGO!Power power supplies provide an isolated (= non-grounded) SELV (Safety Extra
Low Voltage) output voltage at the output. The output of the power supplies is no-load,
overload, and short-circuit proof. If overload occurs, the electronic current limitation limits the
output current to a maximum value (refer to chapter Technical data, Output (Page 25)).
Figure 4-2
Connection of the output voltage
The output voltage is connected via the + and - terminals at the output of the power supply
(see Fig. 4-2). Make sure that the output cables are dimensioned correctly for the maximum
output current rms value and fused accordingly.
Note
When using LOGO!Power in conjunction with devices of the protection class I (with
protective conductor), a connection must be established between "-" and "PE" with at least
1.5 mm².
