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 The connector change from CN41 to CN40 at one of the outdoor units will enable the
outdoor unit to supply power to TB7 . The transmission cable (above 1.25mm
OU 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
TB1
(L1,L2,L3) supply unit PAC-SC51KUA is used, connect the shielded cable to the ground terminal on
the PAC-SC51KUA.

6 To wire PAR-CT01MAU, PAR-40MAAU, and PAC-YT53CRAU, use a wire with a diameter

of 0.3mm

7 MA remote controller and ME remote controller should not be grouped together.
When a PAR-CT01MAU or PAR-40MAAU is connected to a group, no other MA remote
controllers can be connected to the same group.
8 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 11-4. "Address
setting".
9 Indoor board consumes power from TB3. The power balance should be considered
according to System Design 11-3. "System configuration restrictions".
10 If Transmission booster is needed, be sure to connect the shield wires to the both sides
to the booster.
11 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).
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.
