Caution!

■To reduce the risk of electric shock, disconnect the Uninterruptible Power Source from the mains before installing a 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 re- ceptacle. The receptacle must be connected to appropriate branch protection (fuse or cir- cuit 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 de-energize the Uninterruptible Power Source in an emergency, move the 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 ex- cessive 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.

■The Protective Earth conductor of this UPS carries the Leakage Current from the load de- vices (computer equipment). This UPS generates approximately 0.75 mA of leakage cur- rent. To ensure a safe limit of 3.5 mA, the total leakage current of the load devices should be limited to 2.75 mA. If you are unsure of the leakage current from the load devices, en- sure that this product is plugged into a 3-wire receptacle that has a reliable (low impedance) Protective Earth connection to provide a safe path for the leakage current, and replace the powercord to the UPS with one that has a locking type plug (IEC 309) rated a minimum of 10 A. This powercord may require the services of a professional electrician for the installa- tion of the matching wall receptacle.
