NN43021-310 Standard 02.02 October 2008
To eliminate potential of system problems and ensure the best grounding
method possible is used, obtain the services of a certified power contractor or
auditor prior to system installation or cutover.
Note: Refer to Communication Server 1000M and Meridian 1:
Large System Planning and Engineering (NN43021-220) for a complete
description of approved ground sources and methods. Insulated ground
wire must be used for system grounding.
Cabling and connecting the grounding leads
This section covers cabling and connecting the grounding leads for the
Candeo power system. The Candeo’s two grounding leads are:
• the frame or safety ground leads for the frames
• the battery return reference ground lead for the system
CAUTION
Follow local requirements and electrical code
The grounding methods described in this section are
generic. Specific local, provincial, state or federal
electrical codes and grounding requirements, as well as
specific Customer or communication equipment
requirements shall prevail.
CAUTION
Maintain the integrity of the frame or safety ground
The frame or safety ground shall not be confused with the
reference ground lead, nor with the battery return leads.
The frame or safety ground shall be wired in such a way
as not to be carrying any AC or DC current at any time.
