3.1.1.2 Installation Environment 
 
Do not install the UPS in high temperature, low temperature, or damp environments. 
 
Install the UPS away from water sources, heat sources, and flammable or explosive 
materials. Keep the UPS away from direct sunlight, dust, volatile gases, corrosive 
materials, and air dense with salt particles. 
 
Do not install the UPS in environments with conductive metal scraps in the air. 
 
The optimal operating temperatures for valve-regulated lead-acid batteries (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. 
3.1.1.3 Installation Clearances 
Reserve the following clearances around the cabinet to facilitate operations and ventilation: 
 
Reserve at least 800 mm from the front and rear of the cabinet. 
 
Reserve at least 500 mm from the top of the cabinet. 
 
If a top air-flow cabinet is deployed, the UPS can be installed against a wall and no space 
needs to be reserved at the rear. If no top air-flow cabinet is deployed, at least 500 mm 
space should be reserved at the rear for ventilation. If the UPS will be operated from the 
rear, at least 800 mm space should be reserved for operations.
