4.1: Considerations When Installing Meters
Installation of the IQ 150S/250S meter must be performed only by qualified per-
sonnel 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 150S/250S meter, dangerous voltages flow through many parts
of the meter, including: Terminals and any connected CTs (Current Transformers) and PTs (Poten-
tial Transformers), all I/O Modules (Inputs and Outputs) and their circuits. All Primary and Second-
ary 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-limit-
ing 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 volt-
ages.
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 hazardous voltage conditions or damage to CTs, if the meter needs to be removed from
service. CT grounding is optional.
