Operating Precautions

1) The UPS should not be powered up until the entire operation manual has been reviewed,
and understood.
2) The input power source voltage must be within +10% to -15% of the rated input voltage.
The input frequency must be within the rated input frequency range. Voltages and
frequencies outside of the permissible range may cause internal protection devices to
activate.
3) The UPS should not be used with a load whose rated input is greater than the rated UPS
output.
4) Do not use the UPS to provide power to motors that require high starting current or a long
starting time such as vacuum cleaners and machine tools.
5) Do not insert metal objects or combustible materials in the unit's ventilation slots.
6) Do not place, hang, or paste any objects on the top or on the exterior surfaces of the UPS.
