Function of the connector pins for logic signal interface and remote control interface:
Pin 1: Voltage input from remote control (max. voltage +15V, same effect as pressing the on/off
switch on the front panel)
Pin 2: +15V (Impedance 100Ω)
1 2 3 4 5
Pin 3: Reserve logic output 0/15V (Impedance 2.2 kΩ)
Pin 4: Battery logic output 0/15V (Impedance 2.2 kΩ)
Pin 5: GND (Common)
Pin 6: Buzzer output at 7.5 kHz (Open collector)
6 7 8 9
Pin 7: Reserve output (Open collector active low)
Pin 8: GND (Common)
Pin 9: Battery output (Open collector active low)
All the pins are galvanically insulated from the circuits of the UPS.
