7-12 Installing Your RGU
Individual Unit Power-Up
Verifications
1. Verify that the RGU start switch is in the off position.
2. Verify that the incoming phase-to-phase line voltages are within
these tolerances (on the line side of the breaker/motor circuit
protector):
!
ATTENTION: Do not proceed if the RGU fails any of
the checks described in this section. Failure to do so may
result in personal injury and/or equipment damage.
ATTENTION: Perform these verifications for each
RGU in your drive system before connecting the
RGU(s) to the drive lineup.
ATTENTION: The RGU supplies power to the DC
bus whenever the disconnect is closed.
ATTENTION: This unit contains stored energy
devices. To avoid the hazard of electrical shock, verify
that all voltage on capacitors has been discharged before
attempting to service, repair, or remove a drive system
or its components.
ATTENTION: The procedures in this manual should
be performed by qualified personnel who are familiar
with solid-state control equipment and with the safety
procedures in publication NFPA 70E.
