INTRODUCTION
The NSI 2408 dimmer represents a key part of a state of the art, total lighti
ng control system. Combined
with either NSI remote control panels and / or an NSI memory control console, a totally integrated
system is achieved.
The 2408 provides eight channels of 2400 watts each. This dimmer is designed to be permanently
control of house or stage lighting in schools, churches, theaters, buildings, etc. Several
remote control panels such as the NSI 400CP may be mounted at doorways, or other locations at which
ory control console or other suitable
console may be added to the system for special lighting effects. Several 2408 dimmer packs may be
combined for more channels or circuits of lighting.

INPUT WIRING
The 2408 CD/CR must be provided with an 80 amp, 120/240 or
l20/208Y VAC, three wire
electrical service. This service must include two live wires not exceeding 150 volts to ground
and one neutral wire.
In addition the unit must be grounded by conduit or an additional ground wire in accordance with
electrical codes.
The input wiring should be #4 AWG THWN or equivalent copper wire rated for least 75 C.
Pass the input wiring through the 1 1/4" conduit hole in the top of the unit. Allow the wires to drop 4
