Overview of Safe Powering and Grounding
Safe powering and grounding practices are the responsibility of the user.
In most cases, as described in this chapter, you must connect the system to a low-
impedance earth ground before using it. With that connection, any stray voltage or static
electrical charge on the equipment being inspected will be conducted safely to ground and
will bypass the operator.
WARNING
ELECTRICAL SHOCK HAZARD — PROPER GROUNDING
REQUIRED.
In most cases, safe use of this product requires the presence of a protective earth
ground path at the A/C power source. Use of two-conductor extension cords or
any other action that may result in the loss of this ground path are in violation of
the product's safe operating requirements.
WARNING
INSPECTION OF ENERGIZED EQUIPMENT. If the equipment
being inspected could be energized relative to earth ground, connect both the
system and the equipment being inspected to earth ground. If that is not possible,
connect the system either to earth ground or to the equipment being inspected,
whichever the user needs to touch. The user should maintain personal electrical
isolation from the other so as to avoid becoming a path to earth ground.
WARNING
Before attempting any of the procedures in this chapter, carefully
review all guidelines under
“Safety Information”
on page 17.
