8.1 Installing Orbis
The E-Z fit fixing holes are shaped to allow a simple three-step mounting procedure:
1. Fit two screws to the mounting box or surface
2. Place the Orbis base over the screws and slide home
3. Tighten the screws
The base offers two fixing centres at 51 and 60mm.
A guide on the base interior indicates the length of cable to be stripped. The terminals have captive
screws and will not fall out of the terminals. The base is supplied with the screws unscrewed in order
to avoid unnecessary work for the installer.
Five terminals are provided for the cables, four being grouped together for ease of termination. The
terminals are:
1. positive IN
2. positive OUT
3. negative IN and OUT (common terminal)
4. remote LED negative connection
5. functional earth (screen)
