Precautions
Installation Precautions
1) Install the unit in a well-ventilated location; allow at least 10 cm (4 inches) on all sides
for air ventilation and for maintenance.
2) Install the unit in a stable, level, and upright position which is free of vibration.
3) Install the unit where the ambient temperature is within the correct operating range
(see UPS Specifications pages 18 - 21).
4) Do not install the UPS in areas that are subject to high humidity.
5) Do not allow direct sunlight to shine on the unit.
6) Do not install the UPS in areas which are subject to contamination such as high levels
of airborne dust, metal particles, or inflammable gas.
7) Avoid installation near sources of electrical noise, and always make sure that the unit earth
ground is intact to prevent electrical shock and to help reduce electrical noise.
8) Do not install where water or any foreign object may get inside the UPS.
9) This UPS generates and can radiate radio-frequency energy during operation. Although RFI
noise filters are installed inside the unit there is no guarantee that the UPS will not influence
some sensitive devices which are operating close by. If such interference is experienced,
the UPS should be installed farther away from the affected equipment and/or powered from
a different source than that of the affected equipment.
10) User should provide output over current protection for hardwired UPS versions.
See Safety Instructions on page 8 for the correct device rating.
Operating Precautions
1) The UPS should not be powered up until the entire operation manual has been reviewed.
2) The input power source voltage must be within +10% to -30% of the rated input voltage. The
input frequency must be within the rated input frequency range. Voltages and frequencies
outside of the permissible tolerance 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 (over sizing for lock rotor current
required).
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.
