4.1 Cable Termination
Drain wires need to be terminated at the brass cable gland to ensure EMC compliance.
To ensure good earth bonding at entry to the panel enclosure, it is recommended that the cable
drain wires are terminated using Pirelli AXT brass cable glands. These glands have a slotted fixing
thread, which allows the drain wire to be clamped between the gland fixing nut and panel enclosure.
To ensure that a good earth bonding between the drain wire and panel case, a 20mm shakeproof
washer should be used, as shown in the termination diagram below.
5. Connecting to the units
All connections to the unit are via 5mm pitch, 2.5mm
2
capacity, spring leaf terminal blocks. Care
should be taken to use the correct sized terminal screwdriver and not to over tighten the terminals.
If stranded cables are used then care should be taken to ensure that all strands are contained in the
terminal and that there are not any loose strands which may cause short circuits to other terminals
or cables.
