4.1: Considerations When Installing Meters
During normal operation of the Shark® 100S meter, dangerous voltages flow through
many parts of the meter, including: Terminals and any connected CTs (Current Trans-
formers) and PTs (Potential Transformers), all I/O Modules (Inputs and Outputs) and
their circuits. All Primary and Secondary circuits can, at times, produce lethal voltages
and currents. Avoid contact with any current-carrying surfaces.
Do not use the meter or any I/O Output Device for primary protection or in
an energy-limiting capacity. The meter can only be used as secondary pro-
tection.
Do not use the meter for applications where failure of the meter may cause harm or
death.
Do not use the meter for any application where there may be a risk of fire.
All meter terminals should be inaccessible after installation.
Do not apply more than the maximum voltage the meter or any attached device can
withstand. Refer to meter and/or device labels and to the Specifications for all devices
before applying voltages.
Do not HIPOT/Dielectric test any Outputs, Inputs or Communications terminals.
EIG recommends the use of Shorting Blocks and Fuses for voltage leads and power
supply to prevent hazardous voltage conditions or damage to CTs, if the meter needs
to be removed from service. CT grounding is optional.

Installation of the Shark® 100S meter must be performed only by
qualified personnel who follow standard safety precautions during all
procedures. Those personnel should have appropriate training and
experience with high voltage devices. Appropriate safety gloves,
safety glasses and protective clothing is recommended.
