*1 The Ground-fault interrupter should support Inverter circuit.
The Ground-fault interrupter should combine using of local switch or wiring breaker.
*2 Please take the larger of F1 or F2 as the value for F0.
F1 = Total operating maximum current of the indoor units 1.2
F2 = {V1 (Quantity of Type1)/C} + {V1 (Quantity of Type2)/C} + {V1 (Quantity of Type3)/C} + {V1 (Quantity of Others)/C}

PEFY-VMS, PFFY-VCM, PFFY-VEM
Type2

C : Multiple of tripping current at tripping time 0.01s
Please pick up "C" from the tripping characteristic of the breaker.
<Example of "F2" calculation>
*Condition PEFY-VMS 4 + PEFY-VMA × 1, C = 8 (refer to right sample chart)
F2 = 18.6 × 4/8 + 38 × 1/8
= 14.05
16 A breaker (Tripping current = 8 16 A at 0.01s)
*3 Current sensitivity is calculated using the following formula.
G1 = (V2 Quantity of Type1) + (V3 Wire length [km])
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.
7.2. Connecting remote controller, indoor and out-
door 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 control-
ler.
•
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 using a 0.75 mm
core cable. If the distance is more than 10 m, use a 1.25 mm

The MA remote controller and the M-NET remote controller cannot be used at
the same time or interchangeably.
Caution:
Install wiring so that it is not tight and under tension. Wiring under tension
may break, or overheat and burn.

7.3. How to mount remote controller
1. Dismount the upper part of remote controller, and fasten the base of the controller
at the indicated positions with screws provided. (Be careful not to cut the wiring
inside the controller.)
[Fig. 7.3.1] (P.8)
2. Connect the transmission terminal bed inside the control box and the terminal
bed of the remote controller through the notch.

A Notch for transmission line
3. After completing the work of the above items 1 and 2, insert the upper part of
remote controller into its original position.
Note:
•
Unscrew the two screws holding the base of the controller to remove the
2
remote controller.
