Checking Resistance Between
the Control Assembly and the
True Earth Ground
FIRE, EXPLOSION, AND ELECTRIC SHOCK
HAZARD
To reduce the risk of fire, explosion, or electric shock,
the resistance between the supply unit components
and true earth ground must be less than 0.25 ohms.
Have a qualified electrician check the resistance
between each system component and the true earth
ground. The resistance must be less than 0.25 ohms. If
the resistance is greater than 0.25 ohms, a different
ground site may be required. Do not operate the Preci-
sionSwirl module until the problem is corrected.
