E
Diagnosis LED (yellow)
Helps troubleshooting and indicates the following:
- Current Overload:
output voltage below 20Vdc
due to a too high output current,
ready contact is open
- High Temperature:
signal for too high capacitor
temperature (>65˚C), charging and buffering is
still possible, ready contact is open
- Buffer Time Expired:
buffering stopped due to discharged capacitors
- Inhibit Active:
buffering is blocked by the inhibit
signal

F “Warning” LED (red)
- Check Input Voltage:
Indicates a too low or too high input voltage.
The input voltage must be between 23Vdc and
30Vdc to turn-on the output and to start
charging of the capacitors.
- PC-Mode Activated
Indicates, that the PC-Mode (see also section 9) is
activated.

AUU Input Terminals (quick-connect spring-clamp terminal)
UUBUU Output Terminals (quick-connect spring-clamp terminal)
The minus-pole has the same reference as the minus-pole
of the input terminals
C
UU Signal Connector (plug connector)
- Ready:
contact is closed when status LED indicates ready
- Buffering:
contact is closed during buffering
- Inhibit:
a voltage applied on this input signal disables
buffering (e.g. during service)
- PC-Mode:
To activate the PC-mode connect the two pins of
the signal connector together; see also section 9.
D Status LED (green)
- Ready
: capacitors are fully charged, no failures detected
- Charging: capacitors are being charged
- Buffering:
capacitors are being discharged
