 CAUTION

When switching the DIP switch (SW1), be sure to turn off the power supply to the 
indoor unit. Otherwise, the PC board of the indoor unit may be damaged.

 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 dam-
aged 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.
(7) Please do not

CAUTION

To peel the

 lm from the lead cable, use a dedicated tool that will not damage the 

conductor cable.

When installing a screw on the terminal block, do not cut the cable by overtightening 
the screw. On the other hand, an undertightened 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.
