2 SAFETY
ence in earth potential between the instru-
ment and the device to be tested. Check the
continuity of the protective ground wire
before each use.
6] Do not attempt to service the instrument
yourself. Opening or removing covers may
expose you to dangerous voltage. If you at-
tempt to service the instrument yourself the
warranty is no longer valid.
7] Do not use any accessories that are not in-
tended for use together with the instrument.
8] Do not use the instrument for any purpose
other than indicated by the manufacturer.
9] Never connect the test set to energized
equipment.
10] Operation is prohibited in rain or snow.
11] Do not use the test set in an explosive atmo-
sphere.
12] Disconnect the instrument from the mains
before cleaning. Use a damp cloth for clean-
ing. Do not use liquid cleaners or aerosol
cleaners.
Important
1] 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.
2] Always disconnect test leads from power
equipment before attempting to disconnect
them at the test set. The ground connection
must be the first made and the last removed.
Any interruption of the grounding connec-
tion can create an electric shock hazard.
3] 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.
4] The power input plug must be inserted only
into a mating receptacle with a ground con-
tact. Do not bypass the grounding connec-
tion. Any interruption of the grounding con-
nection can create an electric shock hazard.
Determine that the receptacle is properly
wired before inserting the plug.
5] Routine maintenance is all that is required
for these test sets. The cables and connector
panel should be inspected frequently to be
sure all connections are tight and all ground
connections intact.
6] A qualified operator should be in attendance
at all times while the test equipment is in
operation.
7] Refer to IEEE 510-1983, “IEEE Recommended
Practices for Safety in High-Voltage and
High-Power Testing,” for information.
8] Make sure that air intake and fan exhausts
are not blocked
9] Avoid dusty environments and locations be-
cause the accuracy can be affected by long-
term exposure to dust
10] The VAX020 is designed for indoor and
outdoor use. Although a rugged instrument,
it should be well protected when moved or
shipped.
11] The Protective Earth/Ground (PE) of the
VAX020 is connected to the earth/ground pin
of the inlet, making it grounded when the
mains cord is connected.
12] Connect VAX020 to ground using the ground
wing nut on the front panel to ensure pro-
tective grounding independent of the mains
cord being connected or not.
