Transmission cable specifications
Type of cable
Cable diameter
Maximum length of transmission lines for centralized control and indoor/
outdoor transmission lines (Maximum length via indoor units):
Remarks
The maximum length of the wiring between power supply unit for
transmission lines (on the transmission lines for centralized control) and
each outdoor unit and system controller is 200 m [656 ft].
*1 Connected with simple remote controller.
9.1. Power supply wiring
• Use dedicated power supplies for the indoor unit.
• Bear in mind ambient conditions (ambient temperature, direct sunlight, rain water, etc.) when proceeding with the wiring and connections.
• The wire size is the minimum value for metal conduit wiring. If the voltage drops, use a wire that is one rank thicker in diameter. Make sure the power-supply voltage
does not drop more than 10%.
• �����������������������������������������
• Power supply cords of appliances shall not be lighter than design 245 IEC 57, 227 IEC 57, 245 IEC 53 or 227 IEC 53.
• A switch with at least 3 mm [1/8 in] contact separation in each pole shall be provided by the Air conditioner installation.

Apply to IEC61000-3-3 about Max. Permissive System Impedance.
*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}

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 TPEFYP***MS140C × 4 + TPEFYP***MA143A × 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) + (V2 × Quantity of Type2) + (V2 × Quantity of Type3) + (V2 × Quantity of Others) + (V3 × Wire length [km])
G1 Current sensitivity
30 or less 30 mA 0.1 sec or less
