INSTALLATION AND WIRING INSTRUCTIONS

SPECIFICATIONS

Power Supply : 220/240Vac, 50/Hz Switch Action : 1 x SPST, Type 1B Switch Rating : 220/240Vac, 50/60Hz, 6(2)A. Timing Accuracy : ± 1 min./month Enclosure Rating : IP20 Pollution Situation : Degree 2 Max. Ambient Temp. : 55°C Designed to meet BS EN60730-2-7 Dimensions : 112mm wide, 135mm high, 69mm deep

Rated Impulse voltage : 2.5kV

The unit must be installed by a competent electrician and the installation should conform to I.E.E. Regulations. This unit should be wired via full disconnect in accordance with BS EN60730-1, e.g. via a plug and unswitched

socket or double pole switch outlet with neon.

INSTALLATION INSTRUCTIONS

1. Loosen the ﬁ xing screw in the base of the unit to release the grey plastic Wiring Cover. Ensure the protective tape over the thumbwheel remains in place.

2. Holding the unit clockface downwards, press ﬁ rmly in the centre of the wallplate and slide it from the module as shown.

3. Fix the Wallplate/Terminal Block to the wall with countersunk No.8 woodscrews or to a steel box to BS 4662. 1970 or a surface mounting steel or moulded box having centres of 2

4. Referring to the Wiring Diagrams overleaf, connect the unit as shown. Ensure that terminals 3 and 6 are linked where required (Mains Voltage applications) with insulated cable capable of carrying full load current.

5. Ensure all dust and debris have been cleared away from the area, then plug the module ﬁ rmly into the wallplate ensuring that the hook at the top of the wallplate engages with the slot at the back of the body. Press the module down until it locates solidly.

6. Cut a cable aperture in the Wiring Cover if necessary; replace the Wiring Cover, and tighten the ﬁ xing screw.

7. Switch on Mains and test for correct operation as follows:

i) Remove protective tape from the pre-selector wheel. ii) Remove the dial cover and rotate the clock dial two complete

revolutions to clear the mechanism.

ii) Check that all positions of the Selec tor Switch and Tappets operate

correctly. (See instructions in User Booklet.)

8. Replace the dial cover. Finally leave the USER INSTRUCTIONS with the Householder.

9. If the unit is to be left turned oﬀ and is in a dusty atmosphere, protect the pre-selector wheel by re-aﬃ xing the protective tape.
