Wiring
CAUTION
• When connecting the wires to the terminal block using a single core
wire, be sure to perform curling.
Problems with the work may cause heat and fires.
Strip wire end
to this point.
• If the stranded wires must be used, make sure to use the round
crimp-style terminal for connection to the power supply terminal
block. Place the round crimp-style terminals on the wires up to the
covered part and secure in place.
3) Pull the wire and make sure that it does not disconnect. Then fix the wire in place with a wire stop.
