3.6 Installation of sensor alternative 3

Note! Resistive current measurement may not always be possible with 
this special application.

Assemble the EXCOUNT-II sensor to either the pre-assembled coupling, 
figure 3.6.1, or to the pre-assembled terminal, figure 3.6.2, as appropriate 
to the type of PEXLINK transmission line arrester.
