Airflow through the UPS
It is important that the cooling air can freely flow
through the air inlets and outlets of the UPS.
NOTE !
Insufficient distances on both sides of the
UPS could increase the temperature inside
the UPS.
Do not put any object on the top of the
cabinet: it might obstruct the air flow.
Heat evacuation from UPS

The heat must be evacuated
from the environment with a
proper cooling / ventilation
