2.2 Installation Environment
1.
The UPS is designed for indoor use only and should be located in a clean environment with adequate ventila
-
tion to keep the environmental parameters within the required specification.
2.
Make sure that transportation routes (e.g. corridor, door gate, elevator, etc.) and installation area can accom
-
modate and bear the weight of the UPS, the external battery cabinet and handling equipment.
3.
The UPS uses forced convection cooling by internal fans. Cooling air enters the module through ventilation
grills located at the front of the cabinet and exhausted through grills located in the rear part of the cabinet.
Please do not block the ventilation holes.
4.
Ensure that the installation area is adequate for maintenance and ventilation.
5.
Operating temperature range is 0–40°C (32–104°F) and humidity up to 95%. Reference M90U altitude and
temperature derating chart for specific applications. Lead Acid battery life is reduced above 25°C (77F).
6. If necessary, install a system of ventilation fans to avoid excessive room temperature or humidity. Air filters are
necessary if the UPS is operated in a dusty environment.
7.
It is recommended that you parallel the external battery cabinets to the UPS. The following instructions of
