3.3.3 Connecting the load voltage

3−14
Warning
Use only power units which guarantee reliable isolation of
the operating voltages as per IEC 742/EN 60742/VDE 0551
with at least 4 kV isolation resistance (Protected Extra Low
Voltage PELV).
Switch power packs are permitted, providing they guaran
tee reliable isolation in accordance with EN 60950 /
VDE 0805.
By the use of PELV power units, protection against electric
shock (protection against direct and indirect contact) is
guaranteed with the SPC10 in accordance with EN 60204−1/
IEC 204. Safety transformers with the adjacent symbol must
be used for supplying PELV networks. The CP output module
must be earthed to ensure that it functions correctly (e.g.
EMC).
The connected actuators are supplied with + 24 V DC via the
load voltage connection on the output module. Use a cable
for the operating voltage with sufficient cross−sectional area.
