Connect the Signal Cables from Switchgear and Third-Party Auxiliary Products

Install the optional battery temperature sensor in the battery solution. In battery cabinets, install the battery temperature sensor in the top corner of the battery cabinet.

WARNING
Hazard of fire Position the battery temperature sensor as described to ensure correct temperature measurements. Failure to follow these instructions can result in death, serious injury, or equipment damage.

Route the battery temperature sensor cables from the battery solution to the UPS and connect as shown.

NOTE: Battery temperature sensors (SP3OPT006) are available as an optional kit.

NOTE: The battery temperature sensor cables are considered Class 2/SELV. Class 2/SELV circuits must be isolated from the primary circuitry.

Connect the signal cables from the battery breaker(s) in your battery solution for shunt trip or undervoltage (UV) trip connection to the UPS. Follow the illustration for connection with internal 24 VDC supply. The UPS can connect to and monitor up to three (if J8301-10 is used for backfeed) or four battery breakers.

Connect battery breaker 1 to terminal J8301 in the UPS.
Connect battery breaker 2 to terminal J8301 in the UPS.
Connect battery breaker 3 to terminal J8301 in the UPS.
Connect battery breaker 4 to terminal J8301 in the UPS.
For battery breaker trip 4, connect trip unit negative to pin 1 or 4 or 7 of terminal J8301.

NOTE: The following diagram and table demonstrate the battery breaker trip connection with internal 24 VDC supply and pin connections.
