Multiple dimmer installation load ratings
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 row(s). Also, each dimmer MUST be de-rated and its load adjusted in
accordance with the information provided in Table 3.
The maximum Power/Load figures given in table 3 should not be exceeded, taking due care with different
figures for normal GLS tungsten filament lamps compared with Mains Tungsten Halogen Lamps and Low
Voltage Transformers. Use of the latter is not reccommended.

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

Dimmers
The two module dimmers can only be fitted
into two, or four module wide Grid Mounting
Frames, and therefore can only be used with
2, 4, 8 and 12 Gang Frontplates.
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 on page 3:4.
