4.1 Installation Preparations
4.1.1 Site Planning
Installation Environment
● Do not install the UPS in a high-temperature, low-temperature, or damp place
that is beyond the technical specications.
● Install the UPS away from water sources, heat sources, and ammable or
explosive materials. 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.
Clearances
Reserve sucient clearances around the cabinet to facilitate operations and
ventilation:
● Reserve a clearance of at least 800 mm from the front of the cabinets for
ventilation and operations.
● Reserve a clearance of at least 300 mm from the top of the cabinets for
operations.
● Reserve a clearance of at least 300 mm from the rear of the cabinets for
ventilation. Reserve a clearance of at least 800 mm if you need to perform
operations at the rear of the cabinet.
