Back-UPS® - APC Media

3.0 Installation
3.6 Connecting your equipment to the UPS - continued
3.6.7 Once you have determined that your equipment and the UPS are compatible,
plug your equipment into the UPS’s rear panel output receptacles.
Note: Do not plug laser printers into this UPS! The power requirements of a typical laser
printer are much larger than the requirements of other computer peripherals and may trip
the UPS’s rear panel circuit breaker. Plug laser printers into a quality surge suppressor.
Remember that print jobs can be re-queued when the power is restored!
3.7 Test for proper operation
After the UPS has had a chance to recharge its battery, turn on the UPS’s power
I/0 control and switch on your computer equipment. The indicator within the
switch should be illuminated and your equipment should operate normally.
To test the operation of the UPS, simply unplug its input cord or press and hold
the Test switch (on units so equipped) to simulate a utility blackout. The lamp
within the power I/0 switch will flash and UPS will immediately transfer your
equipment to power derived from the UPS’s internal battery. During this time,
the UPS will emit a series of four beeps once every 30 seconds to remind you that
your equipment is operating from a source of power that is limited in duration.
Restore normal operation by releasing the Test control or by plugging in the line
