5.11 Electrical installation
General requirements
Important: All electrical work shall be carried out by
a competent person and shall comply with BS7671
(IEE Regulations).
The boiler is supplied for connection to 230 V, ~ 50 Hz
supply fused at 3 A rating.
Connection to the mains supply shall be made via a
fused 3 pin plug to an unswitched shuttered socket,
both complying to the requirements of BS1363.
(Alternatively, connection may be made via a 3 A fused
double pole isolator having a contact separation of at
least 3 mm in all poles and supplying the boiler and
controls only).
The point of connection to the mains supply must allow
complete electrical isolation of the boiler and its
ancillary controls. It should be readily accessible and
adjacent to the boiler. A 3 core flexible cord according
to BS6500 tables 6, 8 or 16 (3 x 0.75 to 3 x 1.5 mm
2
)
should be used.
Warning: This appliance must be earthed.
Important: Ensure that all cords pass through the
cable clamps in the rear of the control box and are
securely fixed. Ensure that the power supply is
connected such that the current carrying conductors
become taut before the earth conductor should the
supply cord slip from the cable clamp.
Note:
DO NOT use boiler terminal connections 7-8-9.
Warning!
Mains connection terminals L and N remain live
even when the boiler on/off control is switched
off.
