1. Use dedicated power supplies for the unit. Ensure each units are wired individually.2. Bear in mind ambient conditions (ambient temperature,direct sunlight, rain water,etc.) when proceeding with
the wiring and connections.3. The wire size is the minimum value for metal conduit wiring. If the voltage drops, use a wire that is one rank
thickerindiameter. Make sure the power-supply voltage does not drop more than 10%.4. Specific wiring requirements should adhere to the wiring regulations of the region.5. Power supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene sheathed
flexible cord (design 60245 IEC57). 6. A switch with at least 3 mm contact separation in each pole shall be provided by the Air Conditioner installer.7. Do not install a phase advancing capacitor on the motor. Doing so may damage the capacitor and result in fire. The figure in the parentheses indicates the capacity necessary when the "Maximum capacity operation"
settingisselected.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 includesomeamountofdirectcurrent.
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 a breaker and fuse with the correct capacity. Using a fuse or wire of too large
capacitymaycausemalfunctionorfire. Note:
• This device is intended for the connection to a power supply system with a maximum permissible system impedance shown in the above table 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.
• This equipment complies with IEC 61000-3-12 provided that the short-circuit power SSC is greater than or equal to SSC (*2) at the interface point between the user’s supply and the public system. It is the responsibility of the installer or user of the equipment to ensure, by consultation with the distribution network operator if necessary, that the equipment is connected only to a supply with a short-circuit power SSC greater than or equal to SSC (*2).
