Chapter 2 Preparing for Installation
Site Preparation Checklist
DC-Powered Systems
Basic guidelines include the following:
•
Each chassis power supply should have its own dedicated input power source.
•
The circuit must be protected by a dedicated two-pole circuit breaker. The
circuit breaker should be sized according to the power supply input rating and
local or national code requirements.
•
The circuit breaker is considered the disconnect device and should be easily
accessible.
•
The power supply ground should connect to protective earth ground even
though the system ground connection is provided.
•
The DC return is to remain isolated from the system frame and chassis
(DC-I).
