Wiring

ALL WIRING MUST BE IN ACCORDANCE WITH I.E.E. REGULATIONS. THIS UNIT IS FOR FIXED WIRING ONLY.

A switch, having contact separation of at least 3mm in all poles (formerly Class ‘A’), must be incorporated in the ﬁxed wiring as a means of disconnecting the supply.

The unit is a Class II (double insulated) device. A parking terminal is provided for external earth continuity.

The system must be appropriately fused. A fuse rated at no more than 3 Amps should be installed.

The unit has 4 knockouts for surface wiring, care must be taken to ensure that the cable or mini-trunking completely ﬁlls the knockout hole without leaving any gaps.

Final Assembly

Clip the unit onto the hinges on the top of the wallplate and hinge down into position. Tighten the two securing screws using a screwdriver.

Switch on the power – the unit will now be operating according to the built-in programme. Note : the ST9500 is supplied with a factory set clock for faster installation .

Refer to ST9500 User Guide for programming details.
