UBC10.241, UBC10.241-N1 Installation Manual
Functional Description
The output is electronically protected against no-load, overload and short circuit and can supply any
kind of loads, including unlimited inductive loads and capacitive loads.
Do not apply return voltages from the load to the output terminals higher than 35V.
Green Status LED
This LED is on solid, when the battery is charged more than 85%. During battery charging, the LED is
flashing with a slow frequency and rapid flashing is an indication of a buffer event.
Yellow Diagnoses LED
This LED reports an overload situation, an expired buffer time (flashes for 15 minutes), an activated
inhibit input or when the battery should be replaced.
Red Check Wiring LED
This LED indicates a failure in the installation such as too low input or battery voltage, incorrect wiring,
blown or missing battery fuse.
Buffer-time Limiter
The buffer time during a buffer event can be set to 10s, 30s, 1min, 3min, 10min or infinity with the dial
on the front. This can save battery energy for faster recharge and expand the lifetime of the battery.
When dial is set to infinity, buffering continues until stopped by the battery deep-discharge protection.
Inhibit Input
The inhibit input disables or stops buffering. In power supply mode, a continuous input of 10-30V is
required. During buffering, a short input of 10-30V for at least 250ms is required to stop buffering. The
current of the inhibit input is limited to 6mA by the DC-UPS control unit.
Ready, Buffering and Replace Battery Relay Contacts
The Ready contact is closed when the battery is 85% charged and the unit is ready to buffer.
The Buffering contact is closed when the unit is in buffer mode.
The Replace Battery contact is closed when a battery replacement is necessary.
Contact ratings: 60Vdc 0.3A, 30Vdc 1A, 30Vac 0.5A for resistive loads.
