† On some variants pin 1 in connector J1 is not connected. * OUT 3 RTN (–) and OUT 4 RTN (+) are shorted together, and serve as the return for OUT 3 (+) and OUT 4 (–) respectively. OUT 5 RTN (–) and OUT 6 RTN (+) are shorted together, and serve as the return for OUT 5 (+) and OUT 6 (–) respectively. * INHIBIT signal is floating from input and outputs. INHIBIT pin shorted to INHIBIT RTN: Unit is ON ; INHIBIT pin open: Unit is OFF **** BIT pin shorted through a 3.3kΩ resistor to BIT RTN when outputs are within normal range. Open when fault occurs. Note: All pins with identical function and/or designation shuold be connected together for best performance.
