• Install the UPS in a well-ventilated area, keep a minimum distance of 50 cm between the UPS and the wall.
• Keepaway from unstable ground or sources of excessive vibration.
• Keep away from windows, dust, moisture and cold places.
• Keepaway from fire and heat sources.
• Keepawayfromcorrosive gas or fluid.
• Operating temperature: -10*C-+40.C.
• Operating humidity: 10%-90%(non-condensing).

The expected operating altitude of this UPS is less than 1000m. If the installation site is above 1000m above sea level, the load capacity will be correspondingly lower, as shown in the table below.

Altitude
(m)| 1000| 1500| WOO| 2500| 3000| 3500| 4000| 4500| 5000

** Special Precautions:
When the UPS input comes from a generator:
a. Output power capacity must be higher than the UPS rating, otherwise the UPS and generator may not work properly.
b. Output frequency of generator must be in range from 45 to 65Hz, and wave form must be sine wave, otherwise the UPS and generator may not work properly.
