Grounding
DANGER
EXPLOSION HAZARD: Ensure the area in which you perform this operation is non-hazardous.
Performing this operation in a hazardous area could result in an explosion.
The flow computer includes a ground lug on the terminal plate.
1 Ground Lug
• Once you have installed the unit, run a ground wire between the ground lug and a
known good earth ground. You route the ground wire through one of the conduit
fittings.
• Use stranded copper wire 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, tin the wire ends with solder before you insert
them into the chassis ground lug.
• Run the ground wire so that any routing bend in the cable has a minimum radius of
30.48 cm (12 inches) below ground and 20.32 cm (8 inches) above ground.
