Installation
General
Cut cables to length and make earth
connections to grid. Earth: bond grid frame to
metal mounting box. Grid frames are screwed
to back box, modules wired as appropriate and
simply clipped into grid frame by hand. No tools
are necessary. The front plate is screw fixed to
the grid frame to finish the assembly.
To remove or change modules, simply remove
front plate. Individual modules fit perfectly into
the frontplate in flush fitting installations.
Grid mounting
An integral design feature automatically ensures
that the modules fit perfectly into the frontplate in
flush fitting installations.
Some manual adjustment may be required for
surface mounted applications or low profile
ranges (Edge
TM
).
Rocker window labels
The following labels are available for
insertion into window rockers.
Dimmers
The two module size dimmer can be fitted to any
grid mounting frame over 1 gang. The supplied
blank module can be placed at the required pitch
to fill in the second position on the grid.
To avoid overheating when using more than
one dimmer in the same Grid Plus enclosure
it is recommended that the dimmers are
preferentially mounted on the bottom row on
6, 8, 9, 12, 18 and 24 gang enclosures, before
mounting on any other rows and its load
adjusted in accordance with the information
provided in the Load Adjustment Table 1 at the
bottom of the next page.
