To determine whether the MINUTEMAN unit purchased is large enough to
handle your existing equipment, in case the equipment does not have power
requirements labeled, go through the INSTALLATION AND TEST
PROCEDURE. While running in the inverter mode (battery operation), be sure
that maximum power is being utilized by your system. For example, if your load is
a computer with a floppy disc drive, monitor and printer, run the
monitor, printer
and floppy disc drive while the unit is in the inverter mode. Repeat this procedure
several times (5-10). If no operation problems are found, then the MINUTEMAN
is sufficient to handle this load.
INSTALLATION AND TEST PROCEDURE
1.
If your MINUTEMAN Uninterruptible Power Supply uses an external battery pack,
refer to the External Battery Pack Owner's Manual. Complete the
INSTALLATION AND TEST PROCEDURE contained in that manual before
proceeding.
2.
Most MINUTEMAN models have a D.C. breaker switch located on the back, left,
bottom of the unit with a red / green polarity light above the rear access panel
cover. MM250XL does not have the polarity light, since it is not normally used
with external battery packs. Earlier models of the products have an external D.C.
fuse or the D.C. breaker switch inside the control unit and have no polarity light. If
you have no external battery pack connected to your MINUTEMAN, turn on the
D.C. breaker (up position) and the polarity light (if your model has one) will turn
green. If the light doesn't turn green, the internal batteries have become
disconnected in shipment, and you should contact Para Systems, Inc. for
assistance. For units with external battery packs, the polarity light must come on
green when the external battery pack is turned on. Turn on the control unit D.C.
breaker only if this is the case. To turn on an internal D.C. breaker switch, you
must either remove the access panel cover in the rear or remove the unit cover
and push the breaker switch to the forward position.
3.
Plug the unit's power plug into a standard 120VAC receptacle (230VAC
receptacle for 230-volt units) and turn the power switch "on". If commercial power
is acceptable, the "AC Normal" (green) light will come on after a short delay (1.2
seconds). If commercial voltage is not available or is out of range, the unit will go
