Mains
As the system uses hazardous voltages it is recommended that the mains supply connection follow
national wiring rules and is carried out by a suitably qualified person. This equipment must be
permanently connected to a mains fused spur (3A or 5A). The mains cable should be clamped
securely with the cable clamps provided within the equipment/installation kit. Knockouts are provided
on the top, bottom and sides of this equipment and these are intended for conduit or cable glands. As
a mains switch is not provided on the equipment, a readily accessible disconnect device shall be
incorporated in the building installation wiring. Where there is doubt as to the phase of this wiring , the
device, when operated, will disconnect both poles simultaneously.

All wiring in this enclosure requires to be V-2, IEC approved or PVC type. All installation wiring within
this equipment should utilise plastic cable ties to bundle cables so as to provide strain relief for the
cable.
