Preparation for installation.
1. Avoid extremes of ambient temperature; excessive dust, moisture or vibration; flammable
gases; and corrosive or explosive atmospheres.
2.Altitude for normal UPS function should not exceed 1000m.
3.The battery cabinet should work within a temperature range from15℃ to 25℃ .
4.The maximum ambient temperature for normal UPS performance should not exceed
40℃ .
The equipment must be installed in upright position. The equipment requires space to front
and back to enable cooling airflow. Service and maintenance require more than 40cm clear-
ance on right hand side. All cooling air enters at front and exits at unit rear. The required
minimum clearance from unit rear to an obstruction is 50cm. Because the service and user
access is in the front there should be reserved enough space (min 60cm).
