Operating Precautions

1)Install the unit in a well ventilated location; allow at least 4 inches (10 cm) on all sides and 8 inches (20 cm) on back for air ventilation and for maintenance.

2)Install the unit in a stable, level, and upright position that is free of vibration.

3)Install the unit where the ambient temperature is between 32° and 104°F (0° and 40°C).

4)Do not install the UPS in areas that are subject to high humidity.

5)Do not install the UPS in a location that will cause direct sunlight to shine on the unit.

6)Do not install the UPS in areas that are subject to contamination such as high levels of airborne dust, metal particles, or flammable gas.

7)Avoid installation near sources of electrical noise. 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.

Caution

1)The UPS should not be powered up until this entire manual has been reviewed.

2)The input power source voltage and frequency must be within the allowable range specified in Appendix A. Voltages and frequencies outside of the specified tolerance range may cause internal protection devices to activate.
