Multigang Installation-
No Side Sections Removed (No Derating Required)
In multigang installations several controls or controls are grouped
horizontally in one ganging wallbox or in a series of connected
wallboxes. Multigang wallplates are available to simplify and
improve the appearance of this installation. Refer to instruction
sheet (supplied with multigang wallplate).
Installation of controls without removing side sections allows oper-
ation at full capacity (no derating). Follow instructions below. For
retrofit installations side sections can be removed to fit existing
wallboxes. This requires derating and is described in "Multigang
Installation - Side Sections Removed" on page 3.
1. Determine the number of wallboxes necessary by using the
Wallbox Requirement Chart (Table A). When ganging any combi-
nation of small controls (NFTU-5A) and large controls, keep all
small controls together at one end of the gang and all large con-
trols together at the other end of the gang.

Operation
Slide-to-Off Controls
Raise slider to increase light intensity. Lower slider to decrease
light intensity and turn off.
8. Turn power ON. Note: For proper dimming performance,
lamps must be operated at full intensity for 100 hours prior to dim-
ming.
2. When ganging an even number of small controls use
gangable wallboxes with tapped ears. Do not use plaster rings or
gangbox covers. One wallbox in addition to the total number of
controls is required in order to provide space for wallplates (e.g. 4
controls require 5 wallboxes). Place additional wallboxes 3/4" (19
mm) apart from other wallbox(es) to provide space for
wallplate(s). See Figure C.
