9 Electrical Connection
WARNING: This boiler must be earthed.
Remove the screws as diagram 9.1.
Pull the control box forwards to release from the rear slot, allow to pivot and place into position as shown in diagram 9.1.
Using PVC insulated cable to the current issue of BS6500 Table 16, and of a suitable length, thread the cable through the small cable clamp and connect to the appropriate terminals, see diagram 9.2.
Standard colours are, brown - live (L), blue - neutral (N), green/ yellow - earth (E) .
The mains cable outer insulation must not be cut back external to the cable clamp.
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.
It is essential that the polarity is correct.
