Observed
Safety
Practices
Familiarize yourself with all required safety practices of the local utility company, or other owner
of the plant before entering an access area, or connecting a Metrotech transmitter.
Repair and
maintenance
Repairs and service must only be done by Metrotech Corporation or authorized service depart-
ments of Metrotech Corporation. Ensure that the line is de-energized and out of service, before
connecting the transmitter directly to any conductor. NEVER make a direct connection to a live
power cable.
Follow the appropriate safety procedures to avoid the risk of injury if using a clamp on energized
electrical or control lines.
Pay special attention when using a locator in high trafc areas.
Intended
application
Safe operation is only realized when using the equipment for its intended purpose. Using the
equipment for other purposes may lead to human danger and equipment damage.
The limits described under the technical data section may not be exceeded.
Malfunction-
ing Behavior
The equipment may only be used when working properly. When irregularities or malfunctions
appear that cannot be solved consulting this manual, the equipment must immediately be put
out of operation and marked as not functional. Metrotech Corporation must be contacted for
technical support and/or service. The instrument may only be operated when the malfunction is
resolved.
FIVE SAFETY RULES
The ve safety rules must always be followed when working with High Voltage (HV):
De-energize
Protect against re-energizing
Conrm absence of voltage
Ground and short-circuit
Cover up or bar-off neighboring energized parts
Fire ghting in electrical installations:
Recommended extinguishing agent: carbon dioxide (CO2)
Carbon dioxide is electrically non conductive and does not leave residue. It is
safe to use in energized facilities as long as the minimum distances are
observed.
It is essential to observe the safety instruction on the extinguishing agent.
WARNING
Dangers when operating with HV:
Special safety attention is needed when operating HV facilities, especially non-stationary equip-
ment. The regulations VDE 0104 about setting up and operation of electric test equipment, i.e.
the corresponding EN 50191 as well as country-specic regulations and standards must be
observed.
Safety installations may not be by-passed nor deactivated.
Operation requires a minimum two people whereas the second person must be able to activate
the emergency switch in case of danger. To avoid hazardous electric charges of metallic parts
in the vicinity, all metallic parts must be grounded. To avoid drawing dangerous arcs, switching
should only be done in a de-energized condition.
The equipment and all accessories must be connected according to applicable standards VDE,
EN or DIN as well as country-specic regulations.
