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 (hard hats/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 when the threat of lightning is present.
• Warning ! - Seal all cable entry locations immediately after the cabinet is installed to prevent ground moisture
from condensing inside the cabinet and damaging equipment.
Site Selection
The location of a cabinet installation site should be carefully planned in advance. Consider the following factors when select-
ing 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 intersec-
tions 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.
