Grounding With a DC Source (Battery)
If you are using an external DC power source, such as the optional battery, while
inspecting potentially energized equipment, safe use of the XLG3 system requires
verifying a protective earth ground path.
To Provide DC Earth Ground Path
1. Connect an external ground wire to the base unit’s ground lug.
A ground wire (part number XLG3AGROUND) is available from GE Inspection
Technologies.
2. Connect the wire to earth ground or to the equipment being inspected.
Special Grounding Situations
Contact GE Inspection Technologies Technical Support for guidance prior to using the
XLG3 system in any situation where the probe may come into contact with energized
wires or parts.
For example, inspecting buried pipes that are electrically energized to prevent galvanic
corrosion may require special grounding techniques.

shock to the operator may result.
