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.
