If the service you have available is a single phase, 3 wire (split phase) service, convert the pack using the
following directions:
Phase Conversion
1.
Loosen the four bolts on the dimmer power feed busses using a 7/16" socket wrench. See figure 3.
2. Rotate the Phase B1 jumper bar up so that it connects to the Phase A bus. Be sure that the terminal lug on
the Phase A bus is pointing to the right side of the pack and hand-tighten the Phase A bolt.
3. On the Phase B2 bus, rotate the jumper bar down so that it connects to the Phase C bus. Be sure that the
terminal lugs on the Phase B and C busses are pointing to the right side of the pack and hand-tighten both
bolts.
4. Using a 7/16" socket wrench, tighten all four bolts.
Connect the wiring to the ØA, ØC, Neutral and Ground Lugs. This configuration is also suitable for connection to two
phases of a 3 phase, 4 wire system.
