Figure 2-2 Installation Clearances (Top view of rack installation)
1.The UPS should be installed only on the concrete surface or other non-flammable surfaces.
2.As shown in Figure 2-5, 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.
When the UPS uses an external battery, you must install a battery protective device (such as fuse or circuit breaker) in
areas near the battery and use the shortest wiring distance for the connection between the protective device and the
battery.
Storage Environment
When the UPS does not need to be installed immediately, the UPS must be stored indoors to be protected from the
excessive moisture or over-temperature environment. The battery requires dry and low temperature, well-ventilated
environment for storage, and the most suitable storage temperature is 20°C ~ 25°C.
During the battery storage, the battery must be periodically charged according to the battery
instructions. When charging the battery, you can connect the UPS to the mains temporarily to charge
and activate the battery.
