ControlWave Express Instruction Manual (CI-ControlWave Express)
2.2.3 Grounding the Housing
The ControlWave Express enclosure does not include a ground lug.
Instead, you must use one or more of the mounting screws to secure a
ground cable to the unit. Once you have installed the unit, run a ground
wire (#4 AWG max wire size) between one of the mounting screws for
the enclosure to a known good earth ground. For more information on
grounding see the
ControlWave Grounding Supplement
(S1400CW):
Additional grounding guidelines include:

Use stranded copper wire (#4 AWG) 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).
 Using a high-wattage soldering iron, crimp and solder the wire end
you will fasten to the ControlWave Express to a terminal ring/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.
