UPS IST7 (10KVA-40KVA)

User Manual



Put the UPS in the flat floor without vibration and the vertical gradient is less than 5°. Keep

good ventilation around the UPS. The clearance between the rear or the side of UPS and

adjacent devices or wall should be at least 300mm~500mm. Poor ventilation will rise

temperature inside UPS, which will reduce the service life of inner components and even

affect the life span of the UPS.



The UPS must be used below 2000m. If the altitude exceeds 2000m, it needs to decrease

the rated power according to IEC62040-3: 2011 to use.
