Are the humidity and temperature within the specified ranges?
⇒ See §6.1.1 "Checking Installation Environment."
⑥ Has the specified amount of space been provided at the front and back of the UPS?
If the air intake or exhaust vent is blocked, the internal temperature of the UPS will rise, which

the number of discharge cycles.
Ambient temperature has a particularly strong influence as indicated in the following table.
Average Ambient
Operating Temperature
25 C (77 F)
30 C (86 F)
35 C (95 F)
40 C (104 F)
