WARNING- THIS APPLIANCE MUST BE EARTHED
The electrical installation must be carried out by a competent
electrician, and be in strict accordance with the current I.E.E.
regulations for Electrical Equipment in Buildings.
The wires in this mains lead are coloured in accordance with the
following code:
GREEN AND YELLOW: EARTH
BLUE:
NEUTRAL
BROWN:
LIVE
BLACK:
PILOT WIRE
- see also ‘Pilot Wire Connection’
The heater is fitted with a length of flexible cable type H05VV-F
size 4x1.0mm
2
for connection to the fixed wiring of the premises
through a suitable connection box positioned adjacent to the
heater.
A means of disconnection must be incorporated in the fixed wiring
of the premises in accordance with the wiring rules. The supply
circuit to the heater must incorporate a double pole isolating
switch having separation of at least 3mm.
Pilot Wire Connection
The BLACK wire is designed to carry a signal from slot in or wall
mounted Dimplex programmers. If, however a programmer is not
being used, the pilot wire should be isolated in accordance with
the current IEE Wiring Regulations.
IMPORTANT - DO NOT connect the BLACK pilot wire to earth.
Care should be taken with the installation of pilot wire(s) as when
switching to background (set back) they become energised at
240V although only at a current less than 100mA. In every case
a suitable means of isolation must be provided for the pilot wire
and marked to indicate that two sources of supply may be present
at the heater.
Where pilot wires are installed separately from the heater final
sub-circuit they should be protected, double insulated and carry
their own integral earth continuity conductor.
Supplementary Earth Bonding
Should Equipotential Earth Bonding be required the earthing
conductor in the supply cord is deemed to provide the
supplementary bonding connection (see Regulation 544.2.5,
17
th
Edition I.E.E. Wiring Regulations).
