Installation Guidelines
Review the following guidelines before starting installation activities.
General Guidelines
Follow these general guidelines and practices:
Read this document completely before starting any installation activities.
Only qualified personnel should perform the procedures described in this document.
Follow standard safety precautions when performing installation and maintenance tasks.
Always wear standard safety gear when performing installation and maintenance tasks
(hardhats/safety headgear, eye protection, insulated gloves).
For safety, keep bystanders and other unauthorized personnel away from work
operations at all times.
Do not perform installation activities during thunderstorms or when the threat of
lightning is present.
Site Selection
The location of a cabinet installation site should be carefully planned in advance. Consider
the following factors when selecting an installation site:
1.
Functional requirements:
Suitable terrain.
Whenever possible, the cabinet should be located in an area with a
firm flat soil surface that does not require extensive earth work. The location should
not be constantly damp or prone to flooding. Check soil maps of potential sites for
subsurface conditions.
Grounding properties.
The earth at the cabinet location should have a low ground
impedance to provide an effective grounding system for lightning protection and
safety. Perform ground testing to determine the
grounding requirements
Safety.
Whenever possible, the cabinet should be located on vacant property away
from motor traffic to reduce injury risks to maintenance personnel or damage to
equipment. On streets and highways, avoid locations near busy intersections or
curves in the road. Erecting guard rails or concrete pillars can provide additional
safety barriers against motor traffic.
Solar exposure.
Whenever possible in hot or warm climates, avoid locations with
heavy exposure to direct afternoon sun, so as to maximize the life of electronics
equipment in the cabinet. High outdoor temperatures and heavy solar exposure raise
temperatures inside cabinets, a condition that can reduce the life span of equipment.
Conversely, wind exposure improves thermal conditions in a cabinet, so locations
that do not block wind are desirable.
