Condition of range
from which E2 can be taken
R2 can be determined in the same way by substituting
E2 and E3 into the above equation in place of E1 and
E2, respectively. That is, slave unit 1 becomes the
master unit while slave unit 2 becomes slave unit 1.
Select the shortest and heaviest-gauge wires practical for
this wiring.
Connect any one of the output terminals to the GND
(chassis ground) using a shorting bar.
