5.2 Output-side connection
SITOP PSU6200 power supplies provide at their outputs an isolated (= non-grounded) SELV
output voltage (Safety Extra Low Voltage). The output of the power supply is no-load,
overload, and short-circuit proof. If an overload occurs, the electronic current limitation limits
the output current to a maximum value (refer to chapter Technical data (Page 43)).
Figure 5-2 Output-side connection
The output voltage is connected via the "+" and "–" terminals at the output of the power
supply (see Fig. Figure Output-side connection (Page 41)). Ensure that the output cables are
dimensioned correctly for the maximum output current rms value and fused accordingly.
The subsequent digit, e.g.: "+1" designates the unique terminal connection, therefore
simplifying correct wiring.
Note
If the safety concept of the plant or system specifies that the DC output circuit should be
grounded (PELV), then it is permissible that the output voltage of the SITOP power supply is
grounded. In this case, ideally, the grounding at the output should be directly connected from
terminal "
-" of the power supply to a suitable connection point of the protective conductor
em (PE) of the plant or system.
