ELECTRICAL CONNECTIONS
NOTE:
A double pole linked switch with a
minimum contact gap of 3mm in both poles
MUST be fitted in the circuit.
IMPORTANT:
The T40i unit MUST be supplied
by fixed wiring. The supply cable MUST
conform to relevant tables in current IEE
regulations. The electrical rating of the T40i is
shown on the rating label within the unit.
Fig.10
shows a schematic wiring diagram.
•
SWITCH OFF THE ELECTRICITY SUPPLY
AT THE MAINS.
• The cable entry points are shown in
fig.1
.
The cable can be surface clipped, hidden or
via 20mm conduit.
NOTE:
Conduit entry can only be from the
rear. Route the cable into the unit and connect
to the terminal block (fig.11) as follows:
Earth cable to terminal marked
E
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 (fig.11).
NOTE:
The supply cable earth conductor
MUST be sleeved.
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
T40i is to be installed, to conform to current IEE
regulations.
The use of connections within the unit to supply
power to other equipment i.e. extractor fans,
pumps etc. will invalidate the guarantee.
DO NOT switch on the electricity supply
until the cover has been fitted.
