box from the top of the cabinet using appropriate method in accordance with applicable safety standards.
5.3
Positioning of the UPS and Battery Cabinet
The UPS is designed for location in a restricted access location only and should be located where:
The relative humidity does not exceed 95% (non-condensing) and the temperature remains always between 0°C and +40°C. Note:
an optimal temperature for the UPS and especially for VRLA batteries is 20°C- 25°C. The UPS room shall have temperature control
(air-cooling)
Location should be free of dust/debris sources and/or corrosive/explosive gases
All local and national fire protections standards shall be followed.
The location should be free of regular exposure to shock and/or vibration.
The floor material should be non-flammable and strong enough to support the heavy load.
The locations should be convenient for all cabling operations.
The location should afford a front panel access of 36 inches from front of the unit for maintenance or service
If the UPS will be installed in bayed enclosures, partition walls have to be installed as well
Follow all clearance requirements (refer to Tables 5 and 6 and Figures 3 and 4 below) to allow proper airflow to the UPS cabinet.
