Installation Manual
4.0 ELECTRICAL INSTALLATION
All electrical connections must be carried out by a qualified electrician.
To prevent water ingress, the supply cord should be run so the lowest
point is below the cable entry grommet.
For good EMC practice, any sensor cable or switched live cables
should not be placed within 50mm of, or on, the same metal cable
tray as other cables.
If the supply cord is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualified persons in
order to avoid a hazard.
All pole disconnection from the mains as shown in the wiring
diagram, must be incorporated within the fixed wiring and shall
have a minimum contact separation of 3mm in accordance with
latest edition of the wiring regulations.
