1.5 Enclosure Safety Issues
The enclosure and the power supply must be installed by qualified technicians or installers only, using appropriate
mounting hardware in accordance with local codes and construction practices.
The power supply must be installed within a grounded metal enclosure suitable for accommodating broadband
power supplies. If installed outdoors, the cabinet must have a suitable weatherproof rating as a minimum
requirement.
The outer enclosure housing the power supply must be of adequate strength to support the power supply and its
associated batteries. Additionally, the enclosure must afford adequate ventilation for the power supply such that a
minimum free air space of 52 mm (2 inches) remains around all sides and the top of the power supply.
Temperature of the air flowing around the power supply must not exceed 60° C (140° F). Air intake and exhaust
openings within the enclosure must not be less than what is required to maintain this temperature requirement. If
these temperature limits are routinely exceeded or ventilation requirements cannot be attained, a suitable forced-
air cooling system may be required within the enclosure.
