the plug is removed to simulate a power failure (not recommended), do not touch the plug
conductors or the chassis while the lug is removed.
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 sealed lead-calcium rechargeable batteries with the
same voltage and ampere-hour rating as those contained in the units. These batteries
have pressure operated safety vents.
CAUTION
1. Do not dispose of batteries in a fire. They may explode.
2. Do not open or mutilate batteries. Released electrolyte is harmful to the skin and
eyes, and may be toxic.
3. Battery systems can present a risk of electrical shock and high short circuit current.
The current capability of each battery system is sufficient to burn large wire or tools
very rapidly, producing molten metal. The following precautions should be observed
when working on batteries:
a. Disconnect charging source prior to connecting or disconnecting battery
terminals.
b. Remove watches, rings or other metal objects.
c. Use tools with insulated handles.
d. Do not lay tools or any metal parts on top of batteries.
e. Wear protective gloves, eyewear, and boots.
f. Determine if the battery is inadvertently grounded. If inadvertently grounded,
remove source of ground. Contact with any part of a grounded battery can
result in an electrical shock. The likelihood of such shock will be reduced if
such grounds are removed during installation and maintenance.
SELECTION OF UPS LOCATION
Select a location that will provide good air circulation for the UPS. Do not cover the unit air vent
holes or restrict airflow in any way. The unit must have good air circulation at all times.
Avoid locations near heating devices.
Avoid locations near water or excessive humidity.
Avoid locations where the unit is exposed to direct sunlight.
