P1—Remote Emergency Power Off (EPO) (See Section 11-4.)

P2—Auxiliary Dry Contact Inputs (2 sets) (Input Contact A: Pin 1,2 Rated for 12V DC minimum 0.1A (nominal); Input Contact B: Pin 3,4 Rated for 12V DC minimum 0.1A (nominal). See Section 11-5.)

P3—External Battery Cabinet Temperature 1 (Temperature Sensor Inputs from external battery cabinets. See Section 11-6.) P4—External Battery Cabinet Temperature 2 (Temperature Sensor Inputs from external battery cabinets. See Section 11-6.) P5—External Battery Cabinet Temperature 3 (Temperature Sensor Inputs from external battery cabinets. See Section 11-6.) P6—External Battery Cabinet Temperature 4 (Temperature Sensor Inputs from external battery cabinets. See Section 11-6.)

P7—External Battery Status (For use with battery status cable supplied with external battery cabinets-BP480V26B or BP480V40C.)

Note: Do not apply voltages to the REPO contacts or auxiliary dry contacts. Damage to the UPS may result. For the REPO, the switch must be latching in order to keep output power OFF from the UPS output.
