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 or battery pack.
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. Released electrolyte is harmful to the skin
and eyes and may be toxic.
CAUTION -- Although battery system voltages are only 24 or 48 volts, battery systems 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 from 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.
SELECTION OF UPS LOCATION
Select a location that will provide air circulation for the UPS at all times. Do not restrict
airflow in any way.
Avoid locations near heating devices.
Avoid locations near water or excessive humidity.
Avoid locations where the unit is exposed to direct sunlight.
Route power cords so they can not be walked on or damaged.
