Supply voltage terminals (screw terminals)
Designation (A) Description
+ Positive supply voltage terminal (1x)
- Negative (back) supply voltage terminal (2x)
Chassis ground terminal (ring terminal)
Designation (B) Description
chassis ground Connection to device upper side with a ring terminal, suitable for an M4 screw.
The connection of the chassis to the ground (earth) is optional and is only necessary for certain applications.
Signal connection (4-pin connector with screw connection)
Designation (C) Description

Status LED
Designation (D) Description
LED green This green LED shows the following information:
- OFF: capacitors are discharged or the supply voltage is lower than 22 V.
- ON: capacitors are fully charged
- Slow flashing (1.25 Hz): capacitors are being charged.
- Fast flashing (10 Hz): the capacitors are discharging.
Backup threshold value jumper
Designation (E) Description
Backup
threshold - Option 1: Fixed mode (jumper in position 2-3): the device switches to buffer mode as soon as the voltage drops
below 22.5 V.
- Option 2: Variable mode (jumper in position 1-2): the device switches to buffer mode when the input voltage
drops by 1 V. Voltage changes slower than 0.54 V/s are ignored if the voltage is above 22.5 V. Buffering begins
immediately below 22.5 V.
