Output-side connection

SIMATIC ET200SP PS power supplies provide 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 27)).
Figure 5-2
The output voltage is connected via the + and - terminals at the output of the power supply
(see Figure Connecting the output voltage (Page 25)). Ensure that the output cables are
dimensioned correctly for the maximum output current rms value and fused accordingly.
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 SIMATIC 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 system (PE) of the plant or system.
