OPERATION

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.
