WARNING
Read the instructions in this manual before performing installation,
and take note of the following precautions:
Ensure that all incoming AC power and other power sources
are turned OFF before performing any work on the instrument.
Failure to do so may result in serious or even fatal injury
and/or equipment damage.
Before connecting the instrument to the power source, check
the labels on the back of the instrument to ensure that your
instrument is equipped with the appropriate power supply
voltage, input voltages and currents.
Under no circumstances should the instrument be
connected to a power source if it is damaged.
To prevent potential fire or shock hazard, do not expose the
instrument to rain or moisture.
The secondary of an external current transformer must never
be allowed to be 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 secured using an
external strain relief to reduce mechanical strain on the screw
terminals, if necessary.
Only qualified personnel familiar with the instrument and its
associated electrical equipment must perform setup
procedures.
Do not open the instrument under any circumstances when it is
connected to a power source.
