Step 15 - Install filler modules
• If there are less than 6 dimmer modules for a pack, unpack and install filler modules (Part Number 166-360) in slots where there are no dimmers.
This must be done to insure proper cooling while the pack is in operation.
Filler modules look the same as dimmers, but do not have circuit breakers and are installed the same way.
NOTE: Pack should not be operated without all spaces filled. This insures proper cooling.
Step 16 - Test loads
• Switch all dimmer circuit breakers OFF first (switched to the right).
• Switch the test switch on the control module to the TEST position. See Figure 8, page 7. This will turn on the fan.
• Switch on the circuit breaker of each dimmer, one at a time, by moving the breaker handle to the left. Verify that the load is on and the dimmer is operating.
• When testing is completed, switch the test switch on each control module to the NORMAL position. This will turn off the fan and all dimmers.
• Verify that all circuit breakers are in the ON position (switched to the left).
Step 17 - Close door
If desired, label circuits for easy identification later.
Close the front access door. This will aid in proper cooling of the pack and restrict access to the dimmer circuit breakers. See Figure 10.
