Notices
Danger
This symbol indicates the presence of dangerous voltage within and
outside the product enclosure that may constitute a risk of electric
shock, serious injury or death to persons if proper precautions are not
followed.
Caution
This symbol alerts the user to the presence of hazards that may cause
minor or moderate injury to persons, damage to property or damage
to the device itself, if proper precautions are not followed.
Note
This symbol directs the user’s attention to important installation,
operating and maintenance instructions.
Installation Considerations
Installation and maintenance of the ION 7500 / ION 7600 meter should only be
performed by qualified, competent personnel that have appropriate training and
experience with high voltage and current devices. The meter must be installed in
accordance with all Local and National Electrical Codes.
D ANGER
Failure to observe the following instructions may result in severe injury or death.
During normal operation of the ION 7500 / ION 7600 meter, hazardous voltages
are present on its terminal strips, and throughout the connected potential
transformer (PT), current transformer (CT), digital (status) input, control power
and external I/O circuits. PT and CT secondary circuits are capable of generating
lethal voltages and currents with their primary circuit energized. Follow
standard safety precautions while performing any installation or service work
(i.e. removing PT fuses, shorting CT secondaries, etc).
The terminal strips on the meter base should not be user-accessible after
installation.
Do not use digital output devices for primary protection functions. These
include applications where the devices perform energy limiting functions or
provide protection of people from injury. Do not use the ION 7500 / ION 7600 in
situations where failure of the devices can cause injury or death, or cause
sufficient energy to be released that can start a fire. The meter can be used for
secondary protection functions.
Do not HIPOT/Dielectric test the digital (status) inputs, digital outputs, or
communications terminals. Refer to the label on the ION 7500 / ION 7600 meter
for the maximum voltage level the device can withstand.
