out any required operations and who are able to recognize and avoid any possible dangers.

To reduce risk of electric shock or damage to the attached CTs, always open or disconnect
all voltage circuits and apply the shorting bar connections to the current inputs before
installing or servicing the connections to the Terminal Assembly.
Never disconnect the GRID 1 or GRID 2 field wiring while power is present. Personal injury or
equipment damage may result. Finger guards must be installed on the Terminal Assembly
