CAUTION
To avoid possible equipment damage or personal injury, assume that AC voltage is present at the
FERRUPS terminals or receptacles any time AC input voltage or DC battery voltage is supplied.
FERRUPS can provide output voltage from its batteries even when there is no AC input voltage.
Whenever AC input voltage is present, FERRUPS can provide output voltage even when its batteries are
disconnected. Always disconnect the AC input source to make sure there will be no UPS output voltage; if
you have a separate battery cabinet, you must also shut off the DC switch or disconnect the battery cabinet
from the UPS.
To reduce the risk of electric shock, install the UPS in a temperature-controlled indoor area free of
conductive contaminants.

Turn off the equipment you want the FERRUPS to protect.

FE Plug-in Models:
Plug in the UPS. Once you have done this, the AC LINE light
should light
. If the plug does not match your outlet (receptacle),
ask your electrician to install the outlet you need.
QFE Plug-in Models:
Do not use the cord you received to plug in the UPS; this cord is
for plugging your equipment into the UPS. The computer (or
other equipment) that you want to protect should have a power
cord that you can disconnect or “unplug.” Disconnect this cord
from your equipment and use it to plug in the UPS. If you
need to order a UPS power cord, please call the nearest
Best Power office. Once you have plugged in the UPS, the
AC LINE light should light.
Hardwired Models (models that are not plug-in):
Your electrician should have followed the instructions in the Installation Manual to install your UPS
and connect your protected equipment. Turn the AC Disconnect Switch on. The UPS’ AC LINE light
should light
.
The AC LINE light will not light for models FE 1.8, FE 2.1, and FE 3.1 with serial numbers 25000 and up.
NOTE: If you have a separate battery cabinet with a DC switch on the front, turn the switch on now.

Turn the On/Off (
I/O
) switch to the On (
I
) position. (The On/Off switch is shown in step 2.) After a short
startup test, the green READY light should light (on earlier models the light will blink for a few seconds
before remaining lit).
The CHARGING light may be on at this point; this means FERRUPS’ batteries are not fully charged, and
FERRUPS is charging them now. FERRUPS automatically charges the batteries whenever the AC LINE
light is on and the BATTERY POWER light is off. The CHARGING light will turn off when the batteries
have been fully charged; this may take 24 hours. FERRUPS’ runtime (battery backup time) will be shorter
until the batteries have been charged.
