1.Unscrew and remove the service lid.
2.Connect the power supply wiring to the power supply
terminal block.
3.When doing this,press the power supply wiring under the
wire clip tightly.
1.Use the correct screwdriver for tightening the terminal screws.If the blade of screwdriver is too small, the head of the screw might be damaged, and the
