*1 The Ground-fault interrupter should support Inverter circuit. (e.g. Mitsubishi Electric's NV-C series or equivalent).
*2 Ground-fault interrupter should combine using of local switch or wiring breaker.
*3 It shows data for B-type fuse of the breaker for current leakage.
Note:
1 The transmission cable is not-polarity double-wire.
2 Symbol means a screw terminal for wiring.

3 The shield wire of transmission cable should be connected to the grounding terminal at
Outdoor unit. All shield wire of M-Net transmission cable among Indoor units should be
connected to the S terminal at Indoor unit or all shield wire should be connected together.
The broken line at the scheme means shield wire.
4 When the Outdoor unit connected with system controller, power-supply to TB7 of the
outdoor unit(s) is needed. The connector change from CN41 to CN40 at one of the
outdoor units will enable the outdoor unit to supply power to TB7, or an extra power
supplying unit PAC-SC50KUA should be used. The transmission cable (above 1.25mm
shielded, CVVS/CPEVS/MVVS) among Outdoor units and system controllers is called

central control transmission cable. The shield wire of the central control transmission
3-phase 4-wire
cable must be grounded at the Outdoor unit whose CN41 is changed to CN40.
