Output-side connection
At its output, the SITOP PSU8200 1ph power supply provides 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 limiting function
limits the output current to a maximum value (see Section Technical data (Page 37)).
Figure 5-3
Output connection (example: 6EP3334-8SB00-0AY0)
The output voltage is connected via the + and - terminals at the output of the power supply
(see Figure 5-3 Output connection (example: 6EP3334-8SB00-0AY0) (Page 35)). 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, Protected Extra Low Voltage), 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 system (PE) of the plant or system.
