Installing Your RGU 7-13
3. Push the disconnect lever to on. Turn the start switch to on. The
DC bus and control circuitry will power up.
4. The common DC bus voltage will vary based upon the 3-phase
AC input voltage. Verify that the common DC bus voltage is
within these tolerances (RGU not modulating):
Note: The DC bus voltage should be checked at the DC bus
energized board (EA2) as shown in Figure 7.8. Please refer to the
appropriate layout drawings earlier in this manual for board
location.

Where to Check the DC Bus Voltage
5. Verify that the voltage across X1 to X2 on the secondary side of
control transformer PT1, if supplied, is within this tolerance:
6. Verify that all fans are operational.
7. Verify that the DC Bus Energized pilot light is illuminated.
8. Verify that the Not Faulted pilot light, if supplied, is illuminated.
If it is not illuminated, verify that the contacts of the fault circuit
are closed.
