fitted at this stage, see separate installation instructions supplied
with programmer
Take care not to damage any internal wiring.
Using heat resistant (85 o C) cable of at least 0.75mm 2 (24/
0.2mm) and of a suitable length, thread through the grommet at
the rear of the control box, through the cable clamp and connect
to appropriate terminals. Tighten cable clamp screws, see
diagram 5.10.
Standard colours are, brown - live (L), blue - neutral (N) and

The mains cable outer insulation must not be cut back external
to the cable clamp.
Make sure the cable is suitably secured.
When making connections, make sure that the earth conductor
is made of a greater length than the current carrying conductors,
so that if the cable is strained the earth conductor would be the
last to become disconnected.
