Safety

Precautions

The test set and the specimen to which it is connected are a possible source of

high-voltage electrical energy and all persons making or assisting in tests must

use all practical safety precautions to prevent contact with energized parts of the

test equipment and related circuits. Also follow all local and company safety

requirements. Persons actually engaged in the test must stand clear of all parts of

the complete high-voltage circuit, including all connections, unless the test set is

de-energized and all parts of the test circuit are grounded. Persons not directly

involved with the work must be kept away from test activities by suitable

barriers, barricades, or warnings.

Treat all terminals of high-voltage power equipment as a potential electric shock

hazard. There is always the potential of voltages being induced at these terminals

because of proximity to energized high-voltage lines or equipment. Always use a

safety ground stick to ground the high-voltage conductor. A safety ground

jumper must then be installed between all terminals of apparatus under test and

ground. Always disconnect test leads from test specimen before attempting to

disconnect them at the test set. The ground connection on the test set must be

the first made and the last removed. Any interruption of the grounding

connection can create an electric shock hazard.

This instrument operates from a single-phase power source. It has a three-wire

power cord and requires a two-pole, three-terminal, live, neutral, and ground type

connector. The voltage to ground from the live and neutral poles of the power

source must be within the following rated operating voltage:

100-240 V ± 10 %, 50/60 Hz, 16A

Before making connection to the power source, determine that the instrument

rating matches the voltage of the power source and has a suitable two-pole,

three-terminal grounding connector.

The power input plug must be inserted only into a mating receptacle with a

ground contact. Do not bypass the grounding connection. Any interruption of

the grounding connection can create an electric shock hazard. Determine that the

receptacle is properly wired before inserting the plug.
