1. Only supervised and qualified personnel
trained in the usage, installation, operation,
and maintenance of the ground and test
device shall be allowed to work on this
equipment. It is mandatory that this
instruction bulletin, any supplements, and
service advisories be studied, understood,
and followed.
2. Maintenance programs must be consistent
with both customer experience and
manufacturer’s recommendations,
including service advisories and instruction
bulletin(s). A well planned and executed
routine maintenance program is essential
for ground and test devices’ reliability and
safety.
3. Service conditions and ground and test
device applications shall also be considered
in the development of safety programs.
Variables include ambient temperature;
humidity; actual continuous current;
thermal cycling; number of operations;
and any adverse local conditions including
excessive dust, ash, corrosive atmosphere,
vermin and insect infestations.

pecIfIc
When operating the ground and test device
safety precautions must be observed.
Improper use can result in death, serious
personal injury, or damage to the equipment.
!
WARNING
It is important for the user to develop specific
and safe operating procedures to be observed
when using the ground and test device.
The following specific safety precautions must
be observed:
1. Do not close the grounding switch on
an energized circuit. The circuit to be
grounded should always be treated as
energized until proven otherwise.
2. Use great care when opening the test
port shutters to gain access to the test
receptacles. The test receptacles should
always be treated as energized circuits until
proven otherwise.
3. Any test device plugged into the test
receptacles must be properly rated for
the circuit voltage being tested and all
connections must be properly insulated.
4. Use only the test probes (Figure 7) furnished
with the device to plug anything into the
test ports.
Use of other plugs may damage the test port
or may result in a poor connection which
could be dangerous to the operator and/or
damaging to the equipment.
!
CAUTION
5. Even though insulated, the test probes
must not be inserted or extracted from
energized test ports. The test probe
insulation is only one part of a complete
line-to-ground insulation system and the
surface of the test probe may be energized
at a voltage above ground potential when
connection to an energized test port.
