A. PACK LOCATION
The TOPAZ 12 Pack should be located in a dust-free space with an ambient temperature between 32 - 104°F (0-40°C)
and a relative humidity of 10 - 90% without condensation. It should be located on a stable surface suitable for supporting
the weight indicated in Appendix A, Specifications. If packs are stacked on top of each other using the interlocking
feature, make sure that the stack is stable both before and after all cables are terminated. There must be at least 18
inches (457.2 mm) of clearance at the front and back of the pack to allow for cooling and wire routing. Consideration
should be given to the fact that this equipment will produce a slight noise due to dimmer hum and fan operation. Also, no
sound equipment should be placed in the vicinity of the dimmer pack or its wiring. Failure to observe this practice could
result in excessive buzzing in the sound equipment.
B. LINE WIRING
The feeder cable should enter the pack through the strain relief located in the back of the pack. See Figure 1. This cable
clamp will accept 1.15" to 1.98" diameter (29.21 to 50.292 mm) cable. Suggested cables to U.S.A. standards can be
found in Appendix B. The input power (feeder) requirements are indicated on the back of the pack along with the shell
model number.
Locate the line wire lugs, found inside the rear of the pack. Phases A, B, C, the Neutral and the Ground lug are designed
to accept 14-1/0 AWG (2-50mm
should be tightened to the following torque values:
