For solid core wiring

(1)  To connect the electrical terminal, follow the below diagram and connect after looping 

it around the end of the cable.

(2)  Use the speci

fi

 ed cables, connect them securely, and fasten them so that there is no 

stress placed on the terminals.

(3)  Use an appropriate screwdriver to tighten the terminal screws.
 

 Do not use a screwdriver that is too small, otherwise, the screw heads may be 
damaged and prevent the screws from being properly tightened.

(4) Do not tighten the terminal screws too much, otherwise, the screws may break.
(5) See the table for the terminal screw tightening torques.
(6) Please do not

 WARNING

When using solid core cables, do not use the attached ring terminal. If you use the 
solid core cables with the ring terminal, the ring terminal's pressure bonding may 
malfunction and cause the cables to abnormally heat up.

B.  For strand wiring

(1) Use ring terminals with insulating sleeves as shown in the 

fi

 gure below to connect to 

the terminal block.

(2) Securely clamp the ring terminals to the cables using an appropriate tool so that the 

cables do not come loose.

(3) Use the speci

fi

 ed cables, connect them securely, and fasten them so that there is no 

stress placed on the terminals.

(4) Use an appropriate screwdriver to tighten the terminal screws.
 

 Do not use a screwdriver that is too small, otherwise, the screw heads may be 
damaged and prevent the screws from being properly tightened.

(5) Do not tighten the terminal screws too much, otherwise, the screws may break.
(6) See the table for the terminal screw tightening torques.

conductor cable.

When installing a screw on the terminal block, do not cut the cable by overtightening 
the screw. On the other hand, an under tightened screw can cause faulty contact, 
which will lead to a communication failure.

Remove it with the following sequence in case of the state with the grille.

(1)  Use a tool to cut off the terminal on the end of the remote controller cable, and then 

remove the insulation from the cut end of the cable.

(2)  Connect the remote control cable with connecting wire with solder.

Important :  Be sure to insulate the connection between the cables.
