Strain relief
Power supply connection, mains cable strain relief
The EC Conformity is invalid if the mains power line (230 V) is not equipped with a strain relief clamp.
Insert the mains power supply lines to the battery from the bottom into the
central controller unit.
Attach all cables and lines using cable ties at the provided cable entries to relief
the strain.
Remove the sheath of the cable one centimeter behind the cable tie.
Connect the cable leads to the corresponding terminals of the power supply
without too much slack: black to L, blue to N. Protect both cables by tying both
with a cable tie approx. 1 cm in front of the connection terminals (reason: If a
cable breaks, contact with metal parts has to be prevented).
The green-yellow lead is attached to the grounding terminal on the rail mount.
From there a cable leads to the PE connection of the power supply.
