Use the ELECTRODE SENSE LEAD KEY to select
either the - output terminal or the electrode sense (67)
lead for the positive voltage reference.
The work sense (21) lead is used only in rare circum-
stances. For most installations, use the WORK
SENSE LEAD KEY to select the + output terminal for
the negative voltage reference. Consult the factory if
use of the work sense (21) lead is desired.
The two wire feeders can only be connected in the
same manner, either by the Positive Polarity or the
Negative Polarity setup.
