DANGER
Failure to observe the following instructions may result in severe injury or death
and/or equipment damage.
➢
Installation, operation and maintenance of the meter should only be performed by
qualified, competent personnel that have the appropriate training and experience
with high voltage and current devices. The meter must be installed in accordance
with all local and national electrical codes.
➢
Ensure that all incoming AC power and other power sources are turned OFF before
performing any work on the meter.
➢
Before connecting the meter to the power source, check the label on top of the
meter to ensure that it is equipped with the appropriate power supply, and the
correct voltage and current input specifications for your application.
➢
During normal operation of the meter, hazardous voltages are present on its
terminal strips and throughout the connected potential transformers (PT) and
current transformers (CT). PT and CT secondary circuits are capable of generating
lethal voltages and currents with their primary circuits energized. Follow standard
safety precautions while performing any installation or service work (i.e. removing
PT fuses, shorting CT secondaries, …etc).
➢
Do not use the meter for primary protection functions where failure of the device
can cause fire, injury or death. The meter should only be used for shadow protection
if needed.
➢
Under no circumstances should the meter be connected to a power source if it is
damaged.
➢
To prevent potential fire or shock hazard, do not expose the meter to rain or
moisture.
➢
Setup procedures must be performed only by qualified personnel familiar with the
instrument and its associated electrical equipment.
➢
DO NOT open the instrument under any circumstances.
