4.1 Installation Preparations
Floor Loading Capacity
The oor must be able to bear the weight of the UPS and its optional
components. In the case of rack-mounted installation, ensure that the oor can
also bear the weight of the rack.
Installation Environment
● Do not install the UPS in a high-temperature, low-temperature, or damp place
that is beyond the technical specications.
● Keep the UPS far away from water, heat sources, and ammable and
explosive substances. Install the UPS in an environment free of dust, volatile
gas, salt, and corrosive materials. Avoid direct sunlight.
● Do not install the UPS in environments with conductive metal scraps in the
air.
● The optimal operating temperatures for batteries are 20–30°C. Operating
temperatures higher than 30°C shorten the battery lifespan, and operating
temperatures lower than 20°C reduce the battery backup time.
Installation Clearances
● Reserve a clearance of about 100 mm based on the UPS installation
dimensions for the input and output plugs on the rear backplane of the UPS.
● Reserve a clearance of at least 500 mm from the front and rear of the chassis.
