*1 The ground-fault interrupter should support an inverter circuit. (e.g. Mitsubishi Electric's NV-S series or equivalent).
*2 The ground-fault interrupter should combine using of local switch or wiring breaker.
*3 Data for B-type fuse of the breaker for current leakage is shown.
*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.
SYSTEM DESIGN
Note:
1 The transmission cable is a non-polarity double wire.
2 Symbol
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-SC51KUA should be used. The transmission cable (above 1.25mm
shielded, CVVS/CPEVS/MVVS) among outdoor units and system controllers is called
centralized control transmission cable. The shield wire of the centralized 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.
5 MA R/C transmission cable (0.3-1.25mm
R/C transmission cable (0.3-1.25mm
cable to the ME R/C can be extended using a M-NET cable (>=1.25mm
length is counted in the M-Net length. Both Compact MA and ME R/C transmission
cables size 0.75~1.25mm
6 MA remote controller and ME remote controller should not be grouped together.
When a PAR-31MAA is connected to a group, no other MA remote controllers can be
connected to the same group.
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 approximately
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 SW2-1 on.
13 Ensure that the phases of electricity are connected correctly. Phase-reverse, or
unconnected phases could break the controllers.
