NOTE 1
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 2
TB2 and TB3 connector pin 1 is located at the front of the cabinet.
NOTE 3
The Thermal Sensor is optional. If not installed, terminals TB2-11, TB2-12, TB3-11, and
TB3-12 are not present.
