Caution:
•
•
•
•
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.
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.
Be sure to use the appropriate type of overcurrent protection switch. Note that generated overcurrent may include some amount of direct current.
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.
Notes:
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.
•
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.
10.2. 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 con-
troller.
•
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 ME remote controller.
