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 the battery installation environment meets the EN50272-2001 requirements.
The battery ambient temperature should keep constant, because 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 allowable
environmental 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 a fuse or a circuit
breaker) in areas near the battery, and use the shortest wiring distance for the connection between the protective
device and the battery.
