C. DIMMER INSTALLATION
The dimmers may now be installed in the pack. The door on the front of the pack must be open to allow for insertion of
the dimmer modules. Also, the module retaining bracket on the right must be moved to the right by loosening the two
thumb screws. Insert the dimmers in the six slots of the pack. Slide the modules in firmly until they stop. The breakers
should be in the off position while inserting the modules. All slots must have a dimmer or airflow module inserted in order
to maintain proper cooling of the pack.
The TOPAZ 12 PACK dimmer module is available in 1.8kW or 2.4kW sizes for 120V operation, and 2.5kW for 240V
operation. The 1.8/2.4/2.5kW modules are dual dimmers. The model number may be found on the bottom of each
dimmer module.

D. LOAD WIRING
Loads are connected to the portable pack by means of plug-in receptacles on the rear panel of the pack. Dimmer and
load receptacle types and receptacle ampere ratings for the type of pack being used can be found in Table 1 of Chapter I.
Maximum load capacity and branch circuit ratings of the dimmers can be found in Table 2, above. The dimmers are rated
for both incandescent and inductive loads, the latter having a kVA rating equal to the kW rating shown. These dimmers
employ phase-control switching techniques, so inductive loads must be suitable for use with the steep wave front which
this technique produces. The loads should be sized appropriately and mating connectors utilized for proper connections.
Information on load wiring and mating connectors can be found in Appendix C.
E. CONTROL MODULE CONFIGURATION AND INSTALLATION
The electronic control module may now be installed in the pack. There are two types of control modules available which
are designed to work under different conditions. The model number of the control module may be found on the bottom of
its case. Go to the appropriate chapter (Chapter III or IV) for instructions on how to configure the module for your
application.
IMPORTANT. The module must be configured before it is installed to conform to your application.
Please read carefully and make all necessary settings to your control module.
