Turn power OFF. Wire each dimmer according
to steps 3 and 4 in "Single Unit Installation".
4.
Install controls in switchbox(es). Use center
mounting holes for fi rst unit, then use offset mounting
holes as required for proper alignment. Allow
1/32
in (.79 mm) between controls for ease in attaching
faceplates.
5.
Just snap on multigang faceplate (or multiple
single faceplates) and adjust up or down for snug
fi t. Multigang faceplates (with mounting frames and
instructions) are available in a variety of colors and
sizes to simplify and beautify your installation.
Multigang Installation--
Side Sections Removed (Derating Required)
In multigang installations several dimmers or controls
are grouped horizontally in one ganging switchbox
or in a series of connected switchboxes. Multigang
faceplates are available to simplify and improve the
appearance of this installation. A multigang mounting
frame is provided with standard multigang faceplates
which ensures proper alignment of dimmers, easy
application of the faceplate, and a fl at surface for the
installation. Refer to instruction sheet (supplied with
multigang faceplate) when using these components.
1.
Derating is necessary when side sections are
removed. Use Derating Chart (Table B) to determine
maximum wattage of lamps safely dimmed when
side sections are removed. Match the dimmer model
number and the number of side sections removed to
determine the maximum load that can be controlled.

2.
Determine the number of switchboxes necessary
by using the Switchbox Requirement Chart (Table C).
When ganging any combination of small dimmers
(N-600, N-1000) and large dimmers (N-1500, N-2000),
place all small dimmers together at one end of the
gang and all large dimmers at the other end of the
gang.
3.
Remove only inner side sections. Using pliers,
bend side sections as far as you can and then back
to their original positions. Repeat several times
until side sections break off.
Note:
Do not remove outer side sections of the two
dimmers which are on the ends of the gang.
4.
Turn power OFF. Wire each dimmer according
to steps 3 and 4 in "Single Unit Installation".
Grounds need to be common.
5.
Install controls in switchbox(es). Use center
mounting holes. (With large controls, you can
use offset mounting holes as required for proper
alignment). Allow
1/32
in (.79 mm) between controls
for ease in attaching faceplates.
6.
Just snap on a multigang faceplate or multiple
single faceplates (see "Faceplate Cutting" on next
page) and adjust up or down for snug fi t. Multigang
faceplates (with mounting frames and instructions)
are available in a variety of colors and sizes to
simplify and beautify your installation.
