Rules
Operators should be thoroughly trained to follow all of the aforementioned rules, in addition to
any other applicable safety rules and procedures. Defeating any safety system should be
considered a serious offense with severe penalties such as removal from the Hipot testing job.
Allowing unauthorized personnel in the area during a test should also be dealt with as a serious
offense.
Dress
Operators should not wear jewelry that could accidentally complete a circuit.
Medical Restrictions
Personnel with heart ailments or devices such as pacemakers should be informed that the voltages
and currents generated by the instrument are very dangerous. If contacted it may cause heart-
related problems that a person of good health may not experience. Please have the test operator
consult their physician for recommendations.
1.3.4 Instrument Connections
Never perform a hipot test on energized circuitry or equipment.
The instrument is equipped with a safety ground connection, be sure that this is connected
to a good earth ground.
Always connect the return lead first, regardless of whether the item under test is a sample of
insulating material, a component tested with the high voltage test lead, or a cord-connected
device with a two or three prong plug. The return lead should be connected first for any type of
hipot testing.
Plug in the high voltage test lead only when it is being used. Handle its clip only by the insulator---
never touch the clip directly. Be certain that the operator has control over any remote test
switches connected to the Hipot. Double check the return and high voltage connections from the
Hipot and the Line, Neutral, Ground and Case connections from the Line Leakage tester to be
certain that they are proper and secure.
1.3.5 Device Under Test
Never touch the Device Under Test (DUT) or anything connected to it while
high voltage is being applied by the hipot.
