C HECKING T HE S ITE W IRING F AULT (120Vac models only)
After plugging in the UPS, check the Site Wiring Fault (SWF) LED on the front panel of the
unit. If the LED is illuminated the UPS is plugged into an improperly wired AC outlet.
C HARGING T HE B ATTERY
The Enterprise Series UPS will charge the internal batteries whenever the unit is connected
to an AC source and the circuit breaker on the back panel is in the "On" position. It is
recommended that the UPS's batteries be charged for a minimum of 4 hours before use. The
UPS may be used immediately, however, the “on battery” run time may be less than normally
expected.
CAUTION! IF THE UPS INDICATES A SITE WIRING FAULT, HAVE A
QUALIFIED ELECTRICIAN CORRECT THE PROBLEM.
C ONNECTING Y OUR E QUIPMENT
CAUTION! DO NOT CONNECT A LASER PRINTER TO THE BATTERY BACKUP
RECEPTACLES ON THE UPS UNLESS THE UPS IS RATED 2000VA OR
GREATER. A LASER PRINTER DRAWS SIGNIFICANTLY MORE POWER
WHEN PRINTING THAN AT IDLE, AND MAY OVERLOAD THE UPS.
Plug the equipment into the output receptacles on the back panel of the unit. Insure that you
do not exceed the maximum output rating of the UPS (refer to the UPS's back panel or the
Electrical Specifications in this manual).

ON / OFF / Test Switch
The self test feature is useful to verify the correct operation of the UPS and the condition of
the batteries. With the UPS plugged into normal AC press and hold the ON/OFF/TEST SWITCH
for 4 seconds (two beeps) then release the switch. The UPS will perform a five second self
test. Note: The UPS will automatically perform a self test on startup and every
t w o weeks. During the self test the UPS will switch to battery power and the On-Line LED
will blink and the audible alarm will sound as well. The length of the test that is automatically
performed every two weeks is longer than the start-up or user invoked test. This test will
run for approximately fifteen seconds to measure the battery’s capability to provide an
acceptable amount of runtime. If the UPS fails a self test one of the LEDs will remain
illuminated indicating the type of problem. (see section 5 Troubleshooting)
