Keep the UPS far away from water, heat sources, and flammable 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 valve-regulated lead-acid (VRLA)
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.
Ensure that the floor or installation support can bear the weight of the UPS,
batteries, and battery racks.
If the UPS is equipped with a top air-flow cabinet, do not install devices that
are easy to swing on the top of the UPS. Otherwise, the devices may fall off.
Reserve a clearance of at least 950 mm from the front of the cabinet for
ventilation and operations.
Reserve a clearance of at least 500 mm from the top of the cabinet for
operations.
Reserve a clearance of at least 500 mm from the rear of the cabinet for
ventilation.
– Reserve a clearance of at least 800 mm if you need to perform operations
at the rear of the cabinet.
– If the top air-flow cabinet is configured, no space needs to be reserved at
the rear.
