Installation
1. Connect the power cord to a verifi ed grounded 3-wire receptacle.
2. Turn on the power switch of EBPU, the green and yellow LED will be lit indicating AC utility voltage
is present.
3. Charge the batteries for 10hours before use. You may use the EBPU immediately without recharging,
but the backup time may be less than the rating.
4. Connect your computer to the output receptacles of the UPS.
5. To Test backup function, you may disconnect the power cord of the EBPU from wall outlets. The red
LED will fl ash, and buzzer will beep every 5 seconds.
6. When the battery approaches low level, buzzer will beep twice per second until unit shuts down.
7. 4 conditions that cause the EBPU to shut down automatically:
• Battery Low
• Short Circuit
• Overload
• EBPU Fault
Caution
• The EBPU contains voltage that is potentially hazardous. All repairs should be performed by
qualifi ed service personnel.
• The EBPU has its own internal energy source (battery). The output receptacles may be alive when
the EBPU is not connected to an AC supply.
• The EBPU is designed for electronic supply for applications such as electronic patient equipment
and hospital beds containing a substantial rectifi er or capacitive load. It is not suitable for signifi cant
inductive loads.
• Be sure to operate within the power rating of the EBPU. Below 1/2 or 1/3 of the rated power is
recommended for longer backup time and battery life.
• Do not place the EBPU near excessive humidity, direct sunshine, or close to heat-emitting sources.
If the EBPU is out of order, detach power cord and consult your supplier right away. Do not remove
the cover, there are no serviceable parts inside.
• The unit should be supplied by a grounded source. Do not operate the unit without a ground source.
• Do not plug the EBPU’s power cord into itself. That will result in a safety hazard.
