This equipment must be grounded to reduce the
risk of static sparking and electric shock. Electric
or static sparking can cause fumes to ignite or
explode. Improper grounding can cause electric
shock. Grounding provides an escape wire for the
electric current.
Follow these steps to ground the Radar Level
Sensors (M, T):
1.
Loosen the ground screw and attach a ground
wire. A ground wire and clamp, part number
223547, is available from Graco.
2.
Tighten the ground screw securely.
3.
Connect the other end of the ground wire to a
true earth ground.
