TOWER INSTALLATION
1. Turn the On/Off switch on the front of the unit OFF.
2. With load equipment switched OFF, plug it into the UPS output receptacles.
3. Plug UPS into a dedicated and grounded wall receptacle, properly protected by a
circuit breaker or fuse. Use a 15 amp rated device for 1000 or 1500 VA units, and a
20 amp device for 2100 VA units. Turn ON the UPS.
OPTIONAL BATTERY CABINETS
Connect up to two (2) optional battery cabinets to
the UPS for additional run time. DO NOT
connect more than two (2) battery cabinets to
UPS. Cabinets fit beside UPS towers and
underneath rackmount.
Unpack cabinet(s), carefully noting packing
method. Retain packaging. To return cabinet(s),
re-pack as originally shipped. Inspect them for
freight damage. Contact carrier and/or distributor
about freight damage or missing parts.
CAUTION: Battery cabinets are heavy. The
UGX48VBATT and UGX96VBATT weigh 139
Ibs; the UGX72VBATT weighs 111 lbs. Take
proper precautions when lifting or moving them.
Follow UPS installation procedures for your
application (tower or rackmount).
Each battery cabinet has a power cable in the rear. Once the cabinet(s) are in place, plug
the battery cabinet power cable into the UPS battery connector. For two battery cabinets,
plug the power cable of the second battery cabinet into the battery connector of the first
battery cabinet.
UPS OPERATION
Normal Mode
Normally, the utility supplies UPS power. The UPS filters and processes this power to
provide computer grade power to the loads. The UPS also ”float-charges” the batteries and
displays the % UPS output load on the LOAD bar.
Battery Mode
If the UPS senses low voltage or a power outage, the battery instantly supplies UPS power.
In battery mode, the UPS sounds an alarm, turns OFF the AC indicator, and lights the
BATTERY indicator. In this mode, the CAPACITY bar displays battery power remaining
before depletion. Initially, the UPS sounds a 1 second tone every 4 seconds, but increases
to 4 tones every second when there is approximately 2 minutes of battery time remaining.
The UPS supplies internal battery power to a full load for 10 minutes before shutdown.
Increase this time by turning OFF non-critical equipment. Do not turn OFF UPS in battery
mode while supporting a critical load.
Battery Recharge
Upon return of utility power, the UPS automatically reverts to normal operation and
recharges the battery. Significant battery discharge causes the CAPACITY bar to flash 1,
2, or 3 left most segments. As the battery charges, the segments stop flashing one by one
until all light steadily, indicating full charge.
