5.5 Electrical Connection
Thread the mains cable through the cable clamp in the rear of
the box and connect to the terminal strip, see diagram 5.8 and
5.9.
Standard colours are, brown - live (L), blue - neutral (N) and
green and yellow - earth (E).
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.
5.6 Testing
Checks to ensure electrical safety must be carried out by a
competent person.
After installation of the system, preliminary electrical system
checks as below should be carried out:
1. Test insulation resistance to earth.
2. Test earth continuity and short circuit of all cables.
3. Test the polarity of the mains.
Refit the control box.
The installer is requested to advise and give guidance to the
user of the controls scheme used with the boiler.
