Hazard Operation Methods
1. Do not touch the testing area when this scanner is outputting voltage or you
may get electric shock and it may cause death. Be sure to obey the following:
y The earth wire must be connected exactly and use a standard power
cord.
y Do not touch the output terminal.
y Do not touch the test wire that connected to the terminal in test.
y Do not touch any unit under test.
y Do not touch any component that connected to output terminal for
charge.
y Do not touch the test unit right after the test is ended or when the output
is just turned off.
2. The electric shock incident may occur when:
y The earth terminal of EST Scanner is not connected properly.
y The insulating gloves are not in use during test.
y Users touch the test unit right after the test is done.
3. Remote controlling the Tester: The Hipot Tester can be remote controlled
generally for high voltage output via external control signal. When
performing it, it is necessary to follow the control guidelines below for safety
and precautions.
y Do not allow any accidental high voltage output that may cause hazard.
y When there is high voltage output from the Tester, do not allow any
operator or other personnel to touch the UUT, test cable or probe output
and etc.
y Remote control is generally controlled by the high voltage test bar;
however, other control circuits can also be used to control it instead. The
test bar is the switch for controlling high voltage output, so the
connected control wire should not near the high voltage site and test
cable to avoid causing any hazard.
WARNING
Do not tie up the high voltage cable with RS232, Handler and
GPIB control cables or other low voltage side wires. If so, it
could cause the product or PC to be down or damaged.
For detail information of precautions and hazard operations,
please see the chapter 2 Precautions before Use.
