ELECTRICAL CONNECTIONS
Note: A double pole linked switch with a
minimum contact gap of 3mm in both poles
MUST be fitted in the circuit. The supply cable
MUST conform to relevant tables in the current
IEE regulations. The electrical rating of the
heater is shown on the rating label within the
unit.
Fig.7 shows a schematic wiring diagram.
SWITCH OFF THE ELECTRICITY SUPPLY AT
THE MAINS.
Cable entry points are shown in fig.8. The cable
can be surface clipped, hidden or via 20mm
conduit (conduit entry can only be from rear).
Note: The cable grommet for top entry can be
cut to suit different sizes. The cable grommet
MUST be used when the supply cable is routed
through the top entry.
Route the cable into the heater unit and connect
to terminal block as follows:
Earth cable to terminal marked
Neutral cable to terminal marked N
Live cable to terminal marked L
IMPORTANT: Fully tighten the terminal block
screws and make sure that no cable insulation
is trapped under the screws.
Note: The supply cable earth conductor must
be sleeved.
The outer sheath of the supply cable must be
stripped back to just after the clamp.
The earth continuity conductor of the electrical
installation must be effectively connected
electrically to all exposed metal parts of other
appliances and services in the room in which the
heater is to be installed, to conform to current
IEE regulations.
DO NOT switch on the electricity supply until
the cover has been fitted.
