TYPE OF CHECK REQUIREMENT
VALUE /
VERIFICATION
Recommended: between +59 ° F and +77 ° F
(+15 °C and +25 °C)
1. Ambient temperature in the
immediate location of the equipment
Required: between +14 °F and +104 °F
(–10 °C and +40 °C)
2. Humidity and condensation
Verify that there is no water condensation or
dampness within the installation site
3. Ventilation
Verify that sufficient airflow or forced ventilation is
provided for battery cabinets location
4. Foundation and route to installation
site
Verification of adequate structure, space and
clearance for dimensions and weights of the UPS
units and their battery cabinets
5.
When planning the location of the
UPS units, room for access to battery
cabinets and electrical boards is
critical.
Verify 36 in. (91 cm) clearance at rear for access to
cable connections and fuses, and 39 in. (100 cm)
clearance at front for user access and service.
