E Red Check Wiring LED
This LED indicates a failure in the installation (e.g. too low input voltage), wiring, battery or battery fuse.
F
Buffer-time Limiter:
User accessible dial which limits the maximum buffer time in a buffer event to save battery energy. When the
battery begins to recharge after a discharging event, the process is completed much faster since only the energy
which was taken out of the battery needs to be "refilled". The following times can be selected: 10 seconds, 30
seconds, 1 minute, 3 minutes, 10 minutes or infinity (until battery is discharged) which allows buffering until the
deep discharge protection stops buffering.
May. 2008 / Rev. 1.1 DS-UBC10.241-EN
All parameters are specified at an input voltage of 24V, 10A output load, 25°C ambient and after a 5 minutes run-in time
unless otherwise noted. It is assumed that the input power source can deliver a sufficient output current.

A Power Port
Quick-connect spring-clamp terminals, connection for input voltage and
output voltage.
B
Signal Port
Plug connector with screw terminals, inserted from the bottom.
Connections for the Ready, Buffering, Replace Battery relay contacts and
for the Inhibit input. See details in chapter 13.

Green Status LED
Ready: Battery is charged > 85%, no wiring failures are recognized, input
voltage is sufficient and inhibit signal is not active.
Charging: Battery is charging and the battery capacity is below 85%.
Buffering: Unit is in buffer mode.
Flashing pattern of the green status LED:
D Yellow Diagnosis LED
Overload: Output has switched off due to long overload in buffer mode
or due to high temperatures.
Replace battery: Indicates a battery which failed the battery quality test
(SoH test). Battery should be replaced as soon as possible.
Buffer-time expired: Output has switched off due to settings of Buffer-
timer Limiter. This signal will be displayed for 15 minutes.
Inhibit active: Indicates that buffering is disabled due to an active inhibit
signal.
