Output-Side Connection - Siemens LOGO!Power Series Operating Instructions Manual

5.2

Output-side connection

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 an overload occurs, the electronic current limiting function limits the
output current to a maximum value (see Section Technical data (Page 27)).
Figure 5-2
The output voltage is connected via the + and - terminals at the output of the power supply
(see Figure 5-2 Connection of the output voltage (example of 6EP1311-1SH13) (Page 25)).
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.
