4. Electrical connection
The mains supply lead is a multiple-core cable (max.
conductor Ø 2.5 mm):
L
= Phase conductor (usually black or brown)
N
= Neutral conductor (usually blue)
PE
= protective-earth conductor (green / yellow)
= Switched phase conductor (usually black, brown
or grey)
S
= Switch
Important: incorrectly wired connections will produce
a short circuit later on in the product or fuse box. In this
case, you must identify the individual cables and re-
connect them.
