When the power crossover wiring is done, make
it so that the total of the MCA of the connected
RB units and indoor units does not exceed the 15
A. For RB unit MCA, refer to the RB unit instal-
lation manual.
If the capacity of connected RB units and indoor
units exceeds the upper limit, either add breakers
or use a breaker with a greater capacity.
*1: Heat pump type: indoor units,

and RB units.
*2: If the total number of units con-
nected to the breaker exceeds 44,
either add a 30mA breaker, or use
breakers with a greater capacity.

A. 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 specified 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 screw-
driver 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 fix 2 power supply cables with 1 screw.

Cable
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 figure 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 specified 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 screw-
