8. Configure communication and addressing parameters using DIP switches. The E31
requires two addresses, one for each set of 42 current sensors and four auxiliary
inputs. See the Configuration section for more information.
9. Wire RS-485 communications (see diagrams in Wiring section).
10. Connect 0.333VAC current transducers (CTs) to the main conductors by snapping
CTs around lines, observing local codes regarding bending radius (optional;
Figures 9, 10).
