5.6.2. Connecting the PE wire of the AC power cables
Prerequisites:
Tools: wire cutter, wire stripper pliers, wire-end ring, spanner (size 19), torque wrench
(size 19).
Make sure that the main switch of the power supply group for the product
is set to the OFF position. Do a voltage check to make sure that the
electrical power is disconnected from the system. Secure against
resetting.
1.
Make a loop on the PE wire.
For safety, it is recommended to make a loop in the PE wire so it is longer
than the phase wires. This loop ensures that the PE wire is not the first
wire that is disconnected if the Power Cabinet is moved by a collision.
2.
Cut the PE wire of the AC power cable to the proper length to reach the PE rail. Do not
make the wire routing neither too tight nor too loose.
3.
Strip 20 mm of the insulation from the end of the PE wire.
4.
Attach a wire end ring (A) to the end of the PE wire (B).
5.
Remove the M12 bolt, nut and washers from the PE rail.
6.
Fit the bolt (C) with toothed washer (D), the PE wire (B) and the contact washer (E).
7.
Insert the bolt fitted with the PE wire into the PE rail.
8.
Screw from the bottom of the PE rail a toothed washer (D) and a nut (F) on the bolt (C)
9.
Tighten the bolt/nut connection with a tightening torque of 30 Nm.
