Connecting the cables to the PCBs

Keyed connectors are present on different terminal blocks as standard.
Use these to connect the cables to the PCBs If there are no connectors on
the terminal block to be used, take the connector provided with the kit.
Coloured stickers are provided with certain accessories. Use these to
mark each end of the cable with the same colour before passing the
cables into the cable feed-throughs.
1. Insert and screw down the wires in the corresponding connector
inputs.
2. Insert the connector into the corresponding terminal block.
3. Feed the cable into the cable duct and adjust the length of the cable
accordingly.
4. Lock it in position with a cable clamp or a traction arrester device.
Caution
Danger of electric shock: the length of the conductors between the
traction arrester device and the terminal blocks must be such that
the active conductors are put under tension before the earth
conductor.
