BULLETIN 875C, 875CP, 875L CAPACITIVE PROXIMITY SENSOR
IMPORTANT: SAVE THESE INSTRUCTIONS FOR FUTURE USE.
!
ATTENTION: Solid-state devices can be susceptible to radio frequency (RF) interference 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.
!
ATTENTION: If a hazardous condition can result from unintended operation of this device, access to the sensing
area should be guarded.
