General instructions
•
All wiring components, parts which will be obtained locally and materials must comply with the applicable standards of the country and the region.
•
Use copper conductors only.
•
Follow the schematic attached to the unit for details on wiring.
•
The electrical work must be executed entirely by the authorized electricians.
•
The attached gist of wiring gives only an outline and does not refer to any further details on the actual installation work.
•
Install the main switch that can interrupt all the power sources in an integrated manner because this system consists of the equipment utilizing the
multiple power sources.
•
Be sure to install the switch and the fuse to the power line of each equipment.
•
Connect the wires tightly and with no force upon the terminals. Dress the wires so that the covers and other related parts do not get loose. If poorly
connected or loosely placed, an overheat, electric shock or fire may result.

NOTES
1
Up to 3 units can be connected by crossover power supply wiring between outdoor units. However, units of smaller capacity must be connected
downstream.
2
Be sure to connect the power supply wire to the power supply terminal block (X1M) and clamp it as shown in the below hand figure.
3
As this unit is equipped with an inverter, installing a phase advancing capacitor not only will deteriorate power factor improvement effect, but also
may cause a capacitor abnormal heating accident due to high-frequency waves. Therefore never install a phase advancing capacitor.
4
Keep power imbalance to within 2% of the supply rating.
- Large imbalance will shorten the life of the smoothing capacitor
- As a protective measure, the product will stop operating and an error indication will be made when power imbalance exceeds 4% of the supply rating.
