Total operating current of the indoor unit
F0 = 15A or less *2
F0 = 20A or less *2
F0 = 30A or less *2
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}

6.1. Electric wiring
 TPKFYP·HM142 (Fig. 6-1)
Connection can be made without removing the front panel.
1. Open the front grille, remove the screw (1 piece), and remove the electrical
parts cover.
A
* Electrical work can be conducted more effectively with the panel removed.
When attaching the panel, check that the hooks M at five locations on the air
B
outlet side are connected securely.
2. Securely connect each wire to the terminal board.
* In consideration of servicing, provide extra length for each of the wires.
* Take care when using strand wires, because beards may cause the wiring to
short out.
3. Install the parts that were removed back to their original condition.
4. Fasten each of the wires with the clamp under the electrical parts box.

6.2. Power supply wiring
• Install an earth line longer than other cables.
• Power supply codes of appliance shall not be lighter than design 245IEC57 or
227IEC57, 245 IEC 53 or 227 IEC 53.
• A switch with at least 3 mm, 1/8 inch contact separation in each pole shall be
provided by the air conditioner installation.
