2.2.3 Grounding the Housing
Caution
Do not install any modules in the base or expansion housings until you
have mounted and grounded those housings at the designated
installation site.
Base housings have a ground lug (see Figure 2-2 through Figure 2-7)
that accommodates up to a #4 AWG wire size. Once you have installed
the base and any expansion housings, you must run a ground wire
between the base housing ground lug and a known good earth ground.
Note: After you install the PSSM in the base housing, as an added
precaution we recommend that you run a #14 AWG wire from
the TB1-3 power connection (Ground) to the same known good
earth ground.
Additional grounding guidelines include:
 Use stranded copper wire (#4 AWG) for the base housing to earth
ground, and keep the length as short as possible.
 Clamp or braze the ground wire to the ground bed conductor
(typically a stranded copper AWG 0000 cable installed vertically or
horizontally).
 Tin the wire ends with solder (using a high-wattage soldering iron)
prior to inserting the wire into the base housing ground lug.
 Run the ground wire so that any routing bend in the cable has a
minimum radius of 12-inches below ground and 8-inches above
ground.
