instrument

  from the signal source, provided the source remains within the limits  of the chosen auxiliary voltage.

8.5   Fusing

It is recommended that all voltage lines are tted with 1 amp HRC fuses.

8.6   Earth/Ground Connections

For safety reasons, CT secondary connections should be grounded in accordance with local 
regulations.
