Safety precautions
Do not connect devices such as dryers, which have a half-wave rectifier
where only half-cycles of the AC power flows.
● Overcurrent may damage the UPS.
Connect the unit to a wall outlet (commercial power) with a current capacity
of 12A or more.
● Otherwise, the power cord may be heated.
● When equipment with the maximum output capacity is connected, a maximum current of 12A
flows.
Provide secure grounding.
● For a 3P wall outlet, directly connect the AC input plug of the unit to it. Not doing so may cause
an electric shock in the case of unit failure or electric leakage.
● When you use a 3P-2P conversion plug for AC input plug, be sure to perform grounding
before connecting the AC input plug into a wall outlet (commercial power).
Do not disconnect the grounding before disconnecting the AC input plug from a wall outlet
(commercial power).
● Grounding is necessary to enable its surge protection function.
Do not disassemble, repair, or modify the unit.
● Doing so may cause an electric shock or a fire.
Do not install the unit in other than specified orientations.
● Dropping or toppling the unit may cause injury.
● If you install the unit in an orientation other than specified, the unit cannot be protected from a
battery fluid leakage.
Donot put any object on the unit whenever installing it vertically or
horizontally.
● Doing so may cause distortion of/damage to the case, which may cause a fire.
Do not use the unit where the maximum temperature exceeds 40°C.
● The battery becomes week rapidly, which may cause a fire.
● Doing so may cause a failure or malfunction of the unit.
Do not install or store the unit in the places listed below.
● The humidity is lower than 25%. The humidity is higher than 85%. A closed place such as in a
cabinet without clearance. There is flammable gas or corrosive gas. A place subject to vibra-
tion or shock. Outdoors.
● Installation or storing the unit in such a place may cause a fire.
Do not use the unit in a closed place or do not cover the unit.
● Doing so may cause abnormal heating or a fire.
Do not connect equipment that exceeds the output capacity of the unit.
● Overcurrent may damage the UPS or cause it to malfunction.
● Even when connected to the input side, the UPS may fail or malfunction. Make sure to check
the operation before use.
Do not use it in a condition listed below.
- Blocking the ventilating hole
- Placing objects on the unit
- Stacking units (vertically or alongside)
● Doing so may cause abnormal heating, which may cause burns or damage the unit.
