ATTENTION: Solid-state devices can be susceptible to radio frequency interference (RFI) depending on the power
and the frequency of the transmitting source. If RF transmitting equipment is to be used in the vicinity
of the solid state devices, thorough testing should be performed to assure that transmitter operation is
restricted to a safe operating distance from the control equipment and its wiring.
If a hazardous condition can result from unintended operation of this device, access to the hazardous
area should be guarded.
Wiring
All external wiring should conform to the National Electric
Code and applicable local codes. Connect the proximity
switch to the power supply and load as shown in the wiring
diagrams below. If the positive (+) and negative (–) wires on
DC switches are reversed, the switch will not operate properly.
