Maintenance Access
Ensure either through on-site measurement or through review of site A&E, survey, or building
drawings that the outdoor cabinet, as placed at the final site location, will permit:
• Unrestricted access to all points of access to the cabinet interior.
• All cabinet doors to fully open and latch (if equipped). In inclement weather conditions,
unrestrained access doors are a potential hazard to maintenance personnel and equipment
located between the cabinet frame and the door.
• Required separation from certain electrical equipment and panels in compliance with the
latest edition of the National Electrical Code (NFPA 70).
Conduit & Cable Access
Placement of the cabinet should take into consideration the routing, size, bend radius, and
maintenance access of all required power, signal, RF, or other cables and conduits that must
enter and exit the cabinet. Care should be taken in the routing of all conduits placed at ground
level that may restrict access to maintenance battery compartments or that may create a potential
personnel hazard when placed in access routes used by maintenance personnel.
Penetrations
General
Numerous penetrations into an outdoor cabinet may be required, and the total quantity and
location are dependent upon the cabinet design, installed equipment, unique site requirements,
and customer preference. For an environmentally controlled cabinet that is designed to maintain
a weather tight seal, all penetrations - whether utilized or not - should be sealed with an
appropriate and durable seal, gasket, plate, or other material that will maintain the weather-tight
integrity of the outdoor cabinet.
Failure to maintain an adequate seal may allow the entry of moisture, insects, small animals, or
battery gases into the outdoor cabinet. An inadequate seal may also negatively impact the ability
of the environmental equipment to maintain the installed equipment within the designed
operating range, or to incur greater energy utilization.
