Wall Mounted Dimmer Racks
Installation and Maintenance Manual Supplement
Applies to i24, i24e and i48 Quad
Enclosed is a copy of the Installation and Maintenance Manual for the original product. The
wall-mounted units are very similar to the floor-supported units except in the way they mount
and the size of the feeder lugs. The Quad version also includes additional load lugs. This
supplement serves as a modifier to that manual for the wall-mounted product. Please follow the
instructions in the manual except where modified below.
Page 2, Chapter 3 –The wall-mounted units are separate stand-alone dimmer racks. They may
be mounted side-by-side but are not fastened together. Disregard this chapter.
Page 7, Chapter 4 –The wall-mounted units are provided with concentric knock-outs top and
bottom in lieu of un-punched conduit entry panels. Two 1.5 / 2 / 2.5” T.S. and Eight 0.5 / 0.75 /
1 / 1.25” T.S. knock-outs are provided in both locations.
Page 10, Chapter 5 –Also allow 1” clearance on the left side so that the door can fully open.
Page 10, Chapter 6 –The wall-mounted units are attached to the wall via four holes in the back
to accept 5/16” bolts. The rack must be mounted in a substantial manner to support its 179 lbs.
plus the weight of any field wiring and conduit. The use of Unistrut or similar steel channel is
recommended.
Page 11, Chapter 9 –The i24 and i24e are provided with single feeder lugs with the option for a
second set. The i48 Quad is provided with dual feeder lugs.

Page 14, Paragraph 1 –The Quad rack has a second pair of load terminals to the left of those
shown. The wiring to the right pair passes behind the left pair through openings in the support
system for the left pair. The terminal set is wired in the same relationship as the circuit breaker
arrangement in the dimmer module, upper left, upper right, lower left and lower right.

Net Termination
Luma-Net Control Signal Installation Requirements
For i Series e dimmer racks which require the termination of a Luma-Net control run, follow
these instructions.
Connection
The Luma-Net link connects to the backplane of the rack on
TB1 as follows:
Signal Luma-Net 3
Terminal Rack Terminal Rack Label
Rem + 19RAKCOM
Rem -210 RAKCOM
overlined
Common 38GND
+V 47+12V
Although most Luma-Net phoenix style connectors have six
terminals, there is no terminal 5 nor terminal 6 connection at
the dimmer rack. Terminal 6 which is used for the hardware
lock feature has no use at the dimmer rack and the
“terminate” feature which is handled by terminal5 is
handled by the termination jumper.
Termination
If the rack is at the end of the run,Jumper JP2 (Rackcom Termin.) must be installed in the
backplane to terminate the run. The jumper is shipped installed by factory default.
Now the dimmer rack is capable of receiving and processing Luma-Net commands.
Special Installation Requirements for HiLume Dimming Circuits
The HILUME feature is only usable in i Series e. This
style of fluorescent dimming ballast requires (3) wires, (1)
switched, (1) dimmed, and (1) neutral. To accommodate
these requirements, the software will couple the odd-
numbered dimmer with the next even-numbered dimmer.
The odd-numbered dimmer is the variable component and
the even-numbered dimmer is the switched component.
The breakers for these dimmers must be tied together with
the CTP-4-0307 fluorescent handle-tie kit and the rack
slot labeled. Installation instructions for this are included
with the kit.
The odd/even breakers in the i Series Quad are not below each other so they cannot be tied
together; therefore, HILUME is not a quad feature. When the HILUME feature couples the
dimmers the second address is dropped unless the subsequent addresses are moved up dimmer by
dimmer. For this reason it is a good idea to put the HILUME dimmers at the end.
