Do not install the UPS in high temperature, low temperature, and damp areas.
Install the UPS far away from water sources, heat sources, and inflammable or explosive
materials. Keep the UPS free from direct sunlight, dust, volatile gases, corrosive
materials, and salty air.
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.
Reserve a clearance of at least 800 mm on the front of the cabinet.
Reserve a clearance of at least 500 mm on the top of the cabinet.
Keep a clearance of at least 500 mm at the rear of the cabinet. If you need to perform
operations at the rear of the cabinet, keep a clearance of at least 800 mm.
