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 made
through shorting switches and is secured using an external strain relief to
reduce mechanical strain on the screw terminals, if necessary.
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.
