Connecting Remote Controller, Indoor And Outdoor Transmission Cables - Mitsubishi Electric CITY MULTI PEFY-P06NMAU-E4 Manuel D'installation

~ 208/230 V
Indoor
unit 1
• V1 and V2
V1 and V2 are breaker coefficient.
V1: Breaker coefficient of rated current
V2: Breaker coefficient of current sensitivity
The values V1 and V2 differ from depending on the model. Therefore, please refer to IM of each model.
• C: Multiple of tripping current at tripping time 0.01 s
Please pick up "C" from the tripping characteristic of the breaker.
<Example of "F2" calculation>
*Condition PEFY-P·NMAU-E4 × 6, C = 8 (refer to right sample chart)
F2 = 18.6 × 6/8
= 13.95
➞ 15 A breaker (Tripping current = 8 × 15 A at 0.01 s)
*3 Current sensitivity is calculated using the following formula.
G1 = V2 × (Quantity of indoor unit 1) + V2 × (Quantity of indoor unit 2) + V2 × (Quantity of indoor unit 3)
+ ... + V3 × (Wire length [km])
<Example of "G1" calculation>
*Condition: PEFY-P·NMAU-E4 × 5
V2 of PEFY-P·NMAU-E4 = 3.0, Wire thickness and length: 1.5 mm
G1 = 3.0 × 5 + 48 × 0.2
= 24.6
As a result, current sensitivity is 30 mA 0.1 sec or less.
G1 Current sensitivity
30 or less 30 mA 0.1 sec or less
100 or less 100 mA 0.1 sec or less
Warning:
• Be sure to use specified wires for connections and ensure no external force is imparted to terminal connections. If connections are not fixed firmly, heating or
fire may result.
• Be sure to use the appropriate type of overcurrent protection switch. Note that generated overcurrent may include some amount of direct current.
Caution:
• Some installation sites may require attachment of an earth leakage breaker for the inverter. If no earth leakage breaker is installed, there is a danger of electric
shock.
• Do not use anything other than the correct capacity breaker and fuse. Using fuse, wire or copper wire with too large capacity may cause a risk of malfunction
or fire.
Notes:
• This device is intended for the connection to a power supply system with a maximum permissible system impedance (Refer to IEC61000-3-3.) at the interface
point (power service box) of the user's supply.
• The user must ensure that this device is connected only to a power supply system which fulfils the requirement above.
If necessary, the user can ask the public power supply company for the system impedance at the interface point.
• Backup operation
Even when the electrical work has not been completed, the fan and the drain pump can be operated by connecting the jumper (SWE) on the control board to the ON-side
and energizing the terminal block.

Reconnect the SWE on the control board to the OFF-side upon completion of all work.
9.2. Connecting remote controller, indoor
and outdoor transmission cables
• Connect indoor unit TB5 and outdoor unit TB3. (Non-polarized 2-wire)
The "S" on indoor unit TB5 is a shielding wire connection. For specifications
about the connecting cables, refer to the outdoor unit installation manual.
• Install a remote controller following the manual supplied with the remote
controller.
• Connect the "1" and "2" on indoor unit TB15 to a MA remote controller.
(Non-polarized 2-wire)
• Connect the "M1" and "M2" on indoor unit TB5 to a M-NET remote controller.
(Non-polarized 2-wire)
• Connect the remote controller's transmission cable within 10 m [32 ft] using a
0.75 mm [AWG 18] core cable. If the distance is more than 10 m [32 ft], use a
2
1.25 mm [AWG 16] junction cable.
