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.
Service Considerations
Servicing the ION 7700 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 serviced 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 7700
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 per-
forming 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
7700
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 7700
meter for the maximum voltage level the device can
withstand.
C
AUTION
Observe the following instructions, or permanent damage to the meter may occur.
The
ION 7700
meter offers a range of hardware options that affect input ratings. The
ION 7700
meter’s
serial number label lists all equipped options. Applying current levels incompatible with the current inputs
will permanently damage the meter.
The
ION 7700
meter’s chassis ground must be properly connected to the switchgear earth ground for the
noise and surge protection circuitry to function correctly. Failure to do so will void the warranty.
Terminal screw torque: Barrier-type (current, voltage, and relay terminal screws:
1.35 Nm (1.00 ft-lbf)
max. Captured-wire type (digital inputs/outputs, communications, power supply: 0.90 Nm
(0.66 ft.lbf) max.
FCC Notice
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15
of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his own expense.
