Electrical Installation
•
Installation of the EPM6000 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 EPM6000 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 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 protection. 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.
If the equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
