Connect the UPS’s Internal batteries (Figure 1):
NOTE: Battery Disconnect/Connector may vary or be
omitted on some models. Figure 1 illustrates some of the
variations in connectors. Please follow the illustration
which best resembles your UPS.
Procedure for Figure 1: (1, 2)
1.1 Remove the two screws holding the battery door.
1.2 Lay the UPS on its side and open the door
1.3 Gently pull the battery out.
1.4 Connect the two wires to the battery
NOTE: Make sure to observe the polarity (Red-to-Red, Black-to-Black)
NOTE: Small sparks at the battery connections are normal.
1.5 Insert the battery in the UPS. Carefully avoid pinching the wires.
1.6 Close the battery compartment door and replace the screws.
OR
Procedure for Figure 1: (A)
1.1 Locate the ‘Battery Disconnect’ on the rear panel of the UPS. It is typically
a Yellow connector.
1.2 If the Battery Disconnect has a metal cover, remove the fastening screws
and move the cover
1.3 Press the yellow connector into the Battery Jack. A snap will be felt as the
connector partially engages the jack. A second snap will be felt as the
connector securely seats in the Battery Jack.
Connect wiring & charge UPS (Figure 2):
NOTE: Ensure equipment is turned off.
2.1 Connect equipment to UPS
2.2 Connect UPS Power Cord to a suitable power receptacle
2.3 Reset the UPS Circuit Breaker by pushing-in the button
(Circuit breakers may differ on some models)
2.4 Power-up the UPS by pressing the button or
Switch.
2.5 Wait for the Self-Test to complete, then Power-up equipment.

exceeded the capacity of the UPS. A sustained alarm
tone is also emitted.
TEST SWITCH - When operating on Utility
power, the top part of the switch will cause the UPS
to simulate a power outage.
ALARM DISABLE SWITCH - When operating
on battery, the bottom part of the switch will disable

UPS troubleshooting:
NOTE: Troubleshooting procedures may differ depending on UPS model.
Back-UPS troubleshooting
UPS will not turn on
(lamp within power I/O switch is not illuminated), but beeps when power I/O switch
is on
Line cord plug is loose. Check fitting of line cord plug.
Rear panel circuit breaker is tripped. Circuit breaker is tripped when button is extended. Unplug excessive loads
and reset breaker (press button).
Dead wall socket. Check wall socket with a table lamp.
UPS
operates normally, but I/O switch not illuminated)
Lamp inside the I/O switch is blown. You may continue to usethe UPS. It is recommended that the UPS is
serviced.
The UPS operates normally, but the site wiring fault indicator is lit
Building wiring error such as missing ground, hot and neutral polarity
reversal, or overloaded neutral wiring.
A qualified electrician should be summoned to correct the building wiring.
The UPS will not provide rated noise and surge suppression with incorrect
building wiring.
"Cheater" plug or adapter installed onto line cord plug (ground not
connected). Plug the UPS into 2 pole, 3 wire grounding outlet only.
UPS
occasionally emits
a
beep, compu
ter equipment operates normally
The UPS is briefly transferring your equipment to its alternate power
source due to utility voltage sags or spikes.
This operation is normal. The UPS is protecting your computer equipment
from abnormal utility voltages. If the audible alarm becomes annoying, refer
to Option Switch ‘AUDIO SETTING’ section to mute the beeping sound.
UPS
emits
a
beep very often, more
than once or twice and hour. Compu
ter equipment operates normally
Utility voltage is distorted or branch circuits are heavily loaded.
Have your line voltage checked by an electrician. Operating your UPS from
an outlet which is wired to a different branch fuse or circuit breaker may
help. Refer to Option Switch ‘UTILITY TRANSFER VOLTAGE’ section and
lower the transfer voltage if it is known that your equipment will operate
normally at that voltage.
UPS emits loud tone. Power I/O switch is on but computer equipment is not powered.
UPS’s rear panel circuit breaker is tripped (button is extended). Normal utility voltages are known to be present
UPS has shut down due to severe overload. Turn off UPS and unplug excessive loads. Laser printers will overload the
UPS and should be plugged into a quality surge suppressor. Once overload
is removed, reset the circuit breaker (press the button).

Normal UPS operation. None. The UPS is protecting the load.
UPS
does no
t provide expected back up time
The UPS’s battery is weak due to recent outage or it is near the end of
its service life.
Charge the battery. The UPS’s batteries require recharging after an
extended outage. Batteries age faster when put into service often and when
operated at elevated temperatures. If the battery is near the end of its
service life, consider replacing the battery even if the replace battery
indicator is not yet lit.

e wiring fault indicator is lit
Building wiring error such as missing ground, hot and neutral polarity
reversal, or overloaded neutral wiring.
A qualified electrician should be summoned to correct the building wiring.
The UPS will not provide rated noise and surge suppression with incorrect
building wiring.
All indicators are off and the UPS is not operating
The UPS is shutdown and the battery is discharged from an extended
power outage. None. The UPS will return to normal operation when the power is
restored and the battery has a sufficient charge.
The replace battery light is illuminated
Weak batteries. Allow the batteries to rechargefor at least 4 hours. If the problem persists
after recharging, replace the batteries.
Batteries Disconnect or internal battery lugs not connected properly. Confirm the battery connections and battery Disconnect are firmly installed.
