1.0 Introduction
1.1 Overview
Your PowerCell is a high performance standby uninterruptible power system
designed to protect computers and peripheral devices such as monitors, mo-
dems, tape drives, etc. from utility line failures which could result in the loss or
corruption of valuable data. In the event of a utility failure such as a blackout,
brownout or sag, the PowerCell rapidly transfers loads (computer equipment) to
an alternative power source. This alternative power is derived from a battery
within the PowerCell and provides the user with ample time to save files and
properly close operations. A chart in section 9.0 shows how much time your
equipment can remain operating during a utility failure before your PowerCell’s
batteries are drained. Under normal conditions when the utility voltage is within
limits which are safe for your equipment, your PowerCell maintains the battery
in a charged condition and serves to isolate your equipment from surges and high
frequency electrical noise.
After following the installation procedures and reading all the safety instruc-
tions, you’re ready to enjoy computing free from the worry of power problems
and the time consuming process of constantly saving your files!
1.2 User replaceable battery
Your PowerCell provides user-safe access to the batteries for quick, easy replace-
ment. When it has been determined that the UPS's battery is weak and requires
replacement, a new battery kit can be obtained from the factory - simply call the
Customer Service number on the cover of this manual. Your PowerCell's old,
worn battery can be returned to the factory for recycling in the new battery kit's
packaging.
1.3 Site wiring fault indicator
A site wiring fault indicator warns you of hot-neutral reversal, open ground and
overloaded neutral faults. Faulty wiring prevents the safety features and surge
protection circuits built into this UPS from operating properly. Check this
indicator during installation or whenever your building's wiring has been
serviced - call a qualified electrician if the indicator is illuminated.
