SECTION 5
CIRCUIT BREAKER INTERFACE
NOTE: Disregard this section if tripping the battery cabinet breakers via REPO
activation is not required.
Figure 5
shows the location of the Battery Breaker Interface terminal block on the
battery cabinet.
NOTE: Wires to the Battery Breaker Interface terminal block TB4 must not enter
the UPS or battery cabinet through the same port as the input/output or battery
power wires.
Figure 6 – Circuit Breaker Interface Connections
To trip the battery circuit breakers via the REPO of the UPS, connect the battery cabinet
interface connector (TB4) to the UPS per
Figure 6
. If any additional battery cabinets
are –N versions, no other connections are needed.
CAUTION:
The Battery Breaker Interface Board is an electrostatic sensitive
device. The user should be grounded when connecting to this assembly.
CAUTION:
If the battery cabinet circuit breakers trip or are opened, the internal
batteries of the UPS are still connected and providing power to the UPS. They
also cause the terminals of the TB1 and TB2 to be energized with hazardous
voltage.
