Note: Be sure to ground the common Electrode E3 (the
longest Electrode).
• Connect terminal 2 to the contactor’s coil terminal.
Note: The power supply depends on the specifications of the
model.
• With 2-wire connections, only two wires are required between
the 61F-GP-N8R and Electrode Holder, but three wires are
required for the Electrodes.
• The Electrode Holder must be specified for 2-wire connections.
(Resistance R is built into Electrode Holders for 2-Wire
Connections.)
