5.7.1 Connecting Office Battery to Circuit Breaker Panel
See Figure 5-5 [p. 5-14] for the location of terminals on the rear of the CBP. Power cabling
includes the following:
■
–48 V DC battery supply (BATT A1, BATT A2, BATT B1, and BATT B2)
■
Battery return (RTN A1, RTN A2, RTN B1, and RTN B2)
■
Frame ground (FG)
Carefully follow the instructions in this section to avoid personal injury, damage to the
equipment, or both. Installing power cables that are already connected at one end to a
voltage source can result in an electrical accident.
1 Verify that the office-battery ends of the power cables are not connected to the office batteries.
These connections are the last to be made after the CBP has been installed. If necessary, follow
local procedures to disconnect office power from these cables or remove circuit breakers from
the rack CBP. Use a DMM to ensure that the voltage is 0 V DC (with reference to the battery
ground) at the equipment-rack end of the cables.
Note: For FLASHWAVE 7500 equipment, circuit breakers (or fuses) should be sized to ensure that the
maximum input current does not exceed 80 percent of the circuit breaker (or fuse) size. Use 30 A circuit
breakers (or fuses) to ensure that this requirement is met for all configurations of the FLASHWAVE
7500 equipment.
2 Remove the protective covers that protect the A/B battery terminals at both ends on the rear
panel of the CBP. See Figure 5-5 [p. 5-14] for the CBP.
3 Remove the top nuts and washers from the threaded studs for all BATT and RTN
connections being installed.
