15. FRONT SIDE USER ELEMENTS
A Power Port
Quick-connect spring-clamp terminals, connection for input voltage,
output voltage and battery
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 14.
C
Green Status LED
Ready: Battery is charged > 85%, no wiring failure is 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.

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 soon.
Inhibit active: Indicates that buffering is disabled due to an active inhibit
signal.

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 Battery Temperature Selector
A: Same than this unit Temperature compensated end-of-charge voltage
B: 10°C lower than this unit Temperature compensated end-of-charge voltage with an offset
conditional upon the temperature
C: 20°C lower than this unit Temperature compensated end-of-charge voltage with an offset
conditional upon the temperature
D: Battery temperature is 30°C Fixed end of charge voltage for 30°C battery temperature
E: Battery temperature is 20°C Fixed end of charge voltage for 20°C battery temperature
F: Battery temperature is 10°C Fixed end of charge voltage for 10°C battery temperature
Oct. 2009 / Rev. 1.0 DS-UB10.242-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.
