PowerFlex 750-Series AC Drives
Uninterruptible Power Supply Connections - Common DC Input Drives
The user-supplied 120V AC UPS is connected to the lower 120V rail in the back
of the Common DC Input drive cabinet. The UPS rail is only installed when the
P30 UPS Control Bus option is selected. The rail is connected to TB2-1 and
TB2-2 on the Common DC Input drive control panel. To use 120V AC UPS
power, configure the TB5 jumpers as shown in
Table 53 - on page 221 .

ATTENTION: To avoid an electric shock hazard when servicing the drive, a means for
Lockout/Tagout of an external 120V uninterruptible power supply must be provided. Or
the circuit breaker SW5 must be locked and tagged. Locking and tagging the common
bus precharge disconnect switch SW2 alone does not provide sufficient protection
when servicing the drive.
