•
Stand clear of all parts of the high-voltage circuit, including all connections,
unless the device under test is de-energized.
•
Keep other people away from test activities with barricades or warnings.
•
Treat all terminals of high-voltage power equipment as potential electric shock
hazards. Voltages may be induced at these terminals because of proximity to
energized high-voltage lines or equipment.
•
Maintenance must be performed by qualified personnel who is familiar with
the construction and operation of the test set and the hazards involved.
•
Do not expose the NDB-DOC-3 to liquids.
