During the installation of this equipment it should be assured
that the sum of the leakage currents of the UPS and the
connected loads does not exceed 3.5mA.
Connection to any other type of receptacle other than a
single-pole, three-wire grounded receptacle may result in shock
hazard as well as violate local electrical codes.

Do not dispose of batteries in a fire as they may explode.
A battery can present a risk of electrical shock and high short
circuit current. The following precautions should be observed
when working on batteries:
1) Remove watches, rings, or other metal objects from the hands.
2) Use tools with insulated handles.
3) Wear rubber gloves and boots.
4) Do not lay tools or metal parts on top of batteries.
