Connection of the mains lead
The mains lead consists of a 2 or 3
pole cable.
L = Phase conductor
(usually black, brown or grey)
N = Neutral conductor
(usually blue)
PE = Protective-earth
conductor, if present
(green/yellow)
If in doubt, the cable must be identi-
fied with a voltage tester. Switch off
the current again. The wire terminals
are for the mains lead. The phase con-
ductor (L) connects into the lower ter-
minal and the neutral conductor (N)
connects into the middle terminal.
If the green/yellow protective-earth
conductor is present, connect this to
the bottom terminal provided.
Connection of the service lead
The service lead (e.g. light) likewise
consists of a 2 or 3 pole cable which
is connected to terminals N and L'.
The phase conductor of the consumer
(black, brown or grey cable) is con-
nected to the terminal marked L'.
The neutral conductor (blue cable) is
clamped to the terminal marked N
together with the mains lead neutral
conductor. Connect any green/yellow
protective-earth conductor to the
lower terminal.
Important: Getting the cable connec-
tions crossed will produce a short cir-
cuit in the unit or in your fuse box. In
this case, the individual wires must be
re-identified and reconnected. A
mains switch for ON and OFF switch-
ing can of course be installed in the
mains lead.
