Grounding Connections
Grounding - General
NOTE
:
The frame ground (ground ring) connection provided for each framework
serves two purposes:
a. A direct earth ground connection for lightning protection.
b. A common ground potential for electrostatic discharge (ESD) pro-
tection.
Therefore, it should be the first common wiring connection established
once the bay frame has been bolted in place.
NOTE
:
All ground connections to the frame shall be made in such a manner as to
ensure a low-resistance contact with the metal framework. Remove any
paint if necessary. Note that the bay frame has a ground wire attached
which can be removed and repositioned or replaced to conform with local
grounding codes. Whenever this ground strap is repositioned the frame's
paint must be removed as much as necessary to ensure a low-resistance
ground and apply an oxidation preventative such as NO-OX-ID

“A”.
Connections
Step 1:
All individual frames are provided with grounding wires. It will be neces-
sary to terminate or crimp this bay ground wire to the ground wire (or
ground ring) in the cable rack as shown in Figure 2-4.
NOTE
:
In locations where a building ground wire is not apparent, the
bay ground wire should be extended to the MDF framework
near the cable entrance. In all cases conform to local ground-
ing practices.
Step 2: In stations where there is more than one frame in a lineup, each frame
shall be connected to the ground wire.
