4: Electrical Installation
4.1: Considerations When Installing Meters
Installation of the Shark® 100/50 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.
During normal operation of the Shark® 100/50 meter, dangerous voltages flow
through many parts of the meter, including: Terminals and any connected CTs
(current transformers) 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 cur-
rents. 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 requires the use of Fuses for voltage leads and power supply and Shorting Blocks
to prevent hazardous voltage conditions or damage to CTs, if the meter needs to be
removed from service. CT grounding is optional, but recommended.
NOTE:
The current inputs are only to be connected to external current transformers
provided by the installer. The CT's shall be Listed or Approved and rated for the
current of the meter used.
