CAUTION !
To reduce the risk of electric shock, disconnect the Uninterruptible Power Source from
the mains before installing computer interface signal cable (when used). Reconnect the
power cord only after all signalling interconnections have been made.
Connect the Uninterruptible Power Source to a two-pole, three-wire grounding mains
receptacle. The receptacle must be connected to appropriate branch protection (fuse or
circuit breaker). Connection to any other type of receptacle may result in a shock hazard
and may violate local electrical codes.
This Uninterruptible Power Source has an internal energy source (the battery) that
cannot be de-energized by the user. The output may be energized when the unit is not
connected to a mains supply.
To properly deenergize the Uninterruptible Power Source in an emergency, move the
rear panel I/O switch to the O (off) position and disconnect the power cord from the
mains.
Avoid installing the Uninterruptible Power Source in locations where there is water or
excessive humidity.
Do not allow water or any foreign object to get inside the Uninterruptible Power
Source. Do not put objects containing liquid on or near the unit.
To reduce the risk of overheating the Uninterruptible Power Source, avoid exposing the
unit to the direct rays of the sun. Avoid installing the unit near heat emitting appliances
such as a room heater or stove.
