NOTE 1
IBC1 is closest to the UPS.
NOTE 2
The IBC shunt trip is wired in parallel. The IBC battery detect is wired in series.
NOTE 3
TB2 and TB3 terminals are wired together and are identical. TB2 is located at the bottom
of the IBC and TB3 is located at the top of the IBC. Use TB2 for line-up-and-match shunt
trip, and for standalone bottom entry shunt trip and battery detect connections to the
UPS. Use TB3 for connections between multiple IBCs, for line-up-and-match battery
detect, and for standalone top entry shunt trip and battery detect connections to the
UPS.
NOTE 4
If less than four IBCs are installed, the last IBC TB3-5 connection returns to UPS Battery
Detect Building Alarm terminal.
NOTE 5
TB2-3 and TB3-3 terminals in IBC1 can be used to route the return wire to the UPS.
NOTE 6
The Thermal Sensor is optional. If not installed, terminals TB2-11, TB2-12, TB3-11, and
TB3-12 are not present.
