Observe the notes mentioned below when wiring to the power supply
terminal board.
Precautions to be taken for power supply wiring.
(Use a round crimp-style terminal for connection to the power supply
terminal board. In case it cannot be used due to unavoidable reasons,
be sure to observe the following instruction.)
When connecting the connection wires to the terminal board using a single core wire, be sure to perform curling.
Problems with the work may cause heat and fires.
• Pull the wire and make sure that it does not disconnect. Then fix the wire in place with a wire stop.
