Electrical Installation
Considerations When Installing Meters
Installation of the IQ 250/260 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 IQ 250/260 Meter, dangerous voltages flow through many parts of the meter, includ-
ing: 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.
Eaton recommends the use of Shorting Blocks and Fuses for voltage leads and power supply to prevent hazard-
ous voltage conditions or damage to CTs, if the meter needs to be removed from service. CT grounding is optional.
NOTES:
• IF THE EQUIPMENT IS USED IN A MANNER NOT SPECIFIED BY THE MANUFACTURER, THE
PROTECTION PROVIDED BY THE EQUIPMENT MAY BE IMPAIRED.
• THERE IS NO REQUIRED PREVENTIVE MAINTENANCE OR INSPECTION NECESSARY FOR
SAFETY. HOWEVER, ANY REPAIR OR MAINTENANCE SHOULD BE PERFORMED BY THE
FACTORY.
DISCONNECT DEVICE
: The following part is considered the equipment disconnect device.
A SWITCH OR CIRCUIT-BREAKER SHALL BE INCLUDED IN THE END-USE
EQUIPMENT OR BUILDING INSTALLATION. THE SWITCH SHALL BE IN CLOSE
PROXIMITY TO THE EQUIPMENT AND WITHIN EASY REACH OF THE OPERATOR. THE
SWITCH SHALL BE MARKED AS THE DISCONNECTING DEVICE FOR THE EQUIPMENT.
