SETUP AND CONNECTION

Remove all packing material from the unit. Make certain that all holes are free of obstruction on all sides

For portable use, set the Dimmermaster on a smooth, cool surface. Up to 2 packs may be stacked

vertically. Do not remove the feet when stacking. Do not block any vent holes. Make certain that the

vent holes all have at least 6 inches of free air around them. It is essential that this unit have adequate

cooling for safe, reliable performance. Maximum air temperature must not exceed 40 Centigrade (105

The Dimmermaster may be rack mounted in a standard EIA 19-inch equipment rack. The rubber feet

may be removed. Do not remove the top and bottom panels. The Dimmermaster occupies 5.25 inches

of space in the rack, or three rack units. For best cooling, an additional 1.75 inches, or one rack unit,

between packs is recommended. The rack should be ventilated from the top at a minimum of 120 CFM.

The dimmer must be supplied with an amount of current equal to the combined total current of the

lamps it controls. To calculate this current, use the formula amps = watts ÷ volts. For example, if six

2400-watt, 120 volt lighting units are connected to the dimmer, it would require 14,400 ÷ 120, or 120

amps total power. This is available from a three phase 4 wire 40 amp or a single phase 3 wire 60 amp

service. Usually this much power is not required and a 30 - 50 amp service may be used with lower

The Dimmermaster accepts either three phase or single phase power input and is factory configured

for three phase. Line to neutral voltage is always 120 volts. Line 1 to Line 2 voltage is 208 volts in three

phase service and 240 volts in single phase service. It is very important that the input voltages be

checked with a meter to insure that they are correct. A mistake can place 208 to 240 volts across a 120

volt lamp. The breakers will protect the unit but may not save the lamps. A double check of voltages

The power input connector is a terminal block. Each leg of the power feed connects to one terminal on

the dimmer pack. These are marked "L1", "L2", and "L3". The neutral connection is made on the neutral

bar, just to the left of the power block. The ground connection is made on the ground terminal, just to

the right of the power block. The pack has circuit breakers to protect each dimmer channel, but the

When single phase service is used switch S2, located near the center of the board, must be moved

from the "3 phase" position to the "1 phase" position. The power input terminal marked "L3" is not used.

The two blue wires wrapped with red tape must be moved to the terminal marked "L1" and the two

wrapped with black tape to "L2". The tiny blue wire stays in terminal "L3". Please refer to the diagrams
