equipment (see Figure 2-1), to avoid obstructing the UPS ventilation and heat dissipation. Otherwise, the UPS
internal temperature will rise, which will shorten the UPS life.
If necessary, an indoor exhaust fan should be installed to keep the indoor temperature from rising. An air filter should
be used in a dusty environment where the UPS is to be operated.
1. The UPS should be installed only on the concrete surface or other non-flammable surfaces.
2. As shown in Figure 2-1 (top view), the demonstration of the clearance between the rear panel of the cabinet and the wall is
500mm. The clearance should not be less than 200mm, it needs to be considered according to the actaul situation for the sake of
maintenance convenience.
Battery room
A small amount of hydrogen and oxygen will be generated at the end of battery charging, therefore, you must ensure
that the fresh air ventilation of battery installation environment meets the EN50272-2001 requirements.
The battery ambient temperature should keep constant, for the ambient temperature is the main factor to affect the
battery capacity and life. The battery standard operating temperature is 20°C, operation above this temperature will
shorten the battery life, and operation below this temperature will reduce the battery capacity. If the battery average
temperature in operation rises from 20°C to 30°C, the battery life will be reduced by 50%; if the battery temperature in
operation exceeds 40°C, the battery life will be decreased exponentially. In general, the allowed ambient temperature
of the battery is 15°C ~ 25°C. The battery should be kept away from heat and ventilation holes.
