Safety Precautions

• Turn off power to the XA series emergency stop switch

before starting installation, removal, wiring, maintenance,

and inspection of the relays. Failure to turn power off may

cause electrical shock or fire hazard.

• Use the LED unit removal tool when replacing the LED

unit to avoid burn on your hands.

• Use wires of the proper size to meet the voltage and

current requirements, and solder the wires correctly. If

soldering is incomplete, the wire may heat during opera-

tion, causing fire hazard.
