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.
5 MA R/C transmission cable (0.3-1.25mm
2
) must be less than 200m in length, while ME
R/C transmission cable (0.3-1.25mm
2
) must be less than 10m in length. But transmission
cable to the ME R/C can be extend using a M-NET cable (>=1.25mm
2
) when the length
is counted in the M-Net length. Both Compact MA and ME R/C transmission cables size
0.75~1.25mm
2
in thickness.
6 MA remote controller and ME remote controller should not be grouped together.
7 If using 1 or 2 (main/sub) MA remote controller to control more than 1 Indoor unit, use MA
transmission cable to connect all the TB15 terminals of the Indoor units. It is called
"Grouping".
If using 1 or 2 (main/sub) ME remote controller control more than 1 indoor unit, set
address to Indoor unit and ME remote controller. For the method, refer to 2-4. "Address
setting".
8 Indoor board consumes power from TB3. The power balance should be considered
according to System Design 2-3 "System configuration restrictions".
9 If Transmission booster is needed, be sure to connect the shield wires to the both sides
to the booster.
10 The critical current for choosing power source equipment is approximate
1.4 times of total rated current of the Outdoor unit(s) or Indoor unit(s).
11 Numbers shown with ( ) indicates a diameter of the compact remote controller.
12 When System controller (SC) is connected to the system, turn the SW5-1 on.
13 The phases of electricity power must be confirmed to be right used. Phase-reverse, or
phase-missing could break the controllers.
When a PAR-31MAA is connected to a group, no other MA remote controllers can be
connected to the same group.

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-SC51KUA should be used.
The transmission cable (above 1.25mm
2
,
shielded, CVVS/CPEVS/MVVS) among Outdoor units and system controllers is called
central control transmission cable. The shield wire of the central control transmission
cable must be grounded at the Outdoor unit whose CN41 is changed to CN40.
When the power supplying unit PAC-SC51KUA is used, connect the shielded cable to the
ground terminal on the PAC-SC51KUA.

*4 If a large electric current flows due to malfunction or faulty wiring, earth-leakage breakers on the unit side and on the centralized controller side
may both operate.
Depending on the importance of the system, separate the power supply system or take protective coordination of breakers.
*1 The Ground-fault interrupter should support Inverter circuit. (e.g. Mitsubishi Electric's NV-S series or equivalent).
