it is damaged.
4. Do not expose the instrument to rain or moisture.
5. The secondary of an external current transformer
must never be allowed to be an open circuit when the
primary is energized. An open circuit can cause high
voltages, possibly resulting in equipment damage, fire
and even serious or fatal injury
. Ensure that the current
transformer wiring is made through shorting switches
and is secured using an external strain relief to reduce
mechanical strain on the screw terminals, if necessary.
6. Setup procedures must be performed only by
qualified personnel familiar with the instrument and its
associated electrical equipment.
7. DO NOT open the instrument under any
circumstances.
) Read this manual thoroughly before connecting the meter
to the current carrying circuits. During operation of the
meter, hazardous voltages are present on input terminals.
Failure to observe precautions can result in serious or
even fatal injury or damage to equipment.
