Note: Be sure to ground the common Electrode E

3

 (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.)
