Minuteman UPS ALLIANCE SERIES - Manual (Page 4)

2


These UPS units are intended for use in a temperature-controlled, indoor area free of
conductive contaminants. Select a location, which will provide good air circulation for the
UPS at all, times. Avoid locations near heating devices, water or excessive humidity, or
where unit is exposed to direct sunlight. Route power cords so they cannot be walked on
or damaged.

CAUTION -- The UPS uses batteries for generating AC voltages, so output receptacles
may be electrically hot even when the UPS is not connected to commercial power. Trained
service personnel should perform all repairs, since an electrical shock hazard exists.


CAUTION -- Do not remove the cover -- there are no user-serviceable parts inside.


CAUTION -- To prevent electrical shock, the 3-wire plug provides earth ground for the UPS
chassis. Plug the UPS into a 3-wire grounding type, commercial receptacle with the
grounding conductor connected to earth ground at the service equipment. Removal of the
ground pin from the plug or use of a 3-wire-to-2-wire adapter will defeat this safety feature
and may result in a shock hazard. Additionally, if the plug is removed to simulate a power
failure (not recommended), do not touch the plug conductors or the chassis while the plug
is removed. On 120-volt models, improperly connected power will indicate a Site Wiring
Fault.


CAUTION -- Do not allow water or any foreign object to enter the UPS. In case this occurs,
immediately turn the unit power switch off and unplug the MINUTEMAN from the
commercial receptacle.


Servicing of batteries should be performed or supervised by personnel knowledgeable of
batteries and the required precautions. Keep unauthorized personnel away from the
batteries.


When replacing UPS batteries, use the same number of sealed lead-calcium rechargeable
batteries with the same voltage and ampere-hour ratings as those in the UPS. These
batteries have pressure operated safety vents.

CAUTION -- Do not dispose of batteries in a fire. They may explode.


CAUTION -- Do not open or mutilate batteries. Release electrolyte is harmful to the skin
and eyes and may be toxic.

CAUTION -- Although battery system voltages are only 12 VDC, 24 VDC and 36 VDC, the
battery system can still present a risk. The current capability of a battery is sufficient to
burn wire or tools very rapidly, producing molten metal. Observe these precautions when
working on batteries:
1. Turn the UPS off and disconnect it form the wall outlet prior to connecting or
disconnecting battery terminals;
2. Remove watches, rings or other metal objects;
3. Use tools with insulated handles;
4. Wear protective gloves and eyewear;
5. Do not lay tools or other metal parts on top of batteries.
