1. Connect the indoor unit transmission line to transmission terminal block (TB3), or
connect the wiring between outdoor units or the wiring with the centralized control
system to the centralized control terminal block (TB7).
When using shielded wiring, connect shield ground of the indoor unit transmission
line to the earth screw (
C
or
D
) and connect shield ground of the line between
outdoor units and the central control system transmission line to the shield (S)
terminal of the centralized control terminal block (TB7) shield (S) terminal. In

supply and transmission wires through the appropriate knock-out holes, then remove
the knock-out piece from the bottom of the terminal box and connect the wires.
3. Fix power source wiring to terminal box by using buffer bushing for tensile force
(PG connection or the like).
