WARNING
• A high voltage is generated in the FSD output and AUX output terminals, so
before beginning the replacement work, turn off the power to the SL-C Series
and SL-R11 as well as the power of the devices connected to the FSD output
and AUX output terminals. Leaving the power on could result in electric shock.
• When the relay needs to be replaced, replace it with the replacement relay circuit
board (OP-42372) provided by KEYENCE. Do not use parts from another manu-
facturer. Using other parts could cause the SL-C to malfunction, and a serious
accident causing a serious injury or death.
