Please note the following maximum cable sizes:
Earth and Neutral bars:
2.5kW Phase terminals:
5kW Phase terminals:
10kW Phase terminals:
It is occasionally necessary to use larger cable sizes on the 2.5kW and
5kW dimmers, and an adapter kit is available, with 10mm
DIN terminals for oversized cables. See section 10.7 for part numbers.
Note that bootlace ferrules are required to be fitted to the earth and neu-
tral wires if stranded cable is used.
a)
Terminating load wiring.
Note that numbering is
always from left to right, ie:
Earth 1–12, Neutral 1–12,
Phase 1–12. The same rule
applies to 3x10kW and
6x5kW Power Assemblies.
Tip:
It's easier to fit the
bottom Power
Assembly first,
terminate the load
wiring, then fit the
middle Power
Assembly, and so on.
