Connection method for the power supply cable and indoor/outdoor unit connections
Follow the installation instruction manual provided with the indoor unit to set up the indoor unit wiring and the
indoor/outdoor connections. Provide separate power supplies for the indoor and outdoor units.
This equipment complies with EN/IEC 31000-3-12 provided that the short-circuit power Ssc is greater than or equals
to U-4LA:1850kVA, U-5LA:2200kVA, U-6LA:2200kVA 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 consulting with the distribution
network operator if necessary that the equipment is connected only to supply with a short-circuit power Ssc greater
than or equals to U-4LA:1850kVA, U-5LA:2200kVA, U-6LA:2200kVA.

NOTE
Use the standard power supply cables for Europe (such as H05RN-F or H07RN-F which conforms to CENELEC
(HAR) rating specifications) or use the cables based on IEC standard. (245 IEC57, 245 IEC66)
Urban Network Method
Connect all devices to one bus line irrelevant of the refrigerant system.
Use less than 128 for the total number of connecting devices.
Recommend
If the number of connecting devices is big and since the units have to be connected to each
refrigerant system, it is recommended to connect between each outdoor unit.
(Refer to the diagram on the right).
Should the device malfunction and cause abnormal communications to the other devices due
to multiple connections, disconnect the outdoor units. It is easy to identify the faulty device and
the system can be restored by disconnecting that device.
Warning
When using the urban network method for wiring, only switch the power ON for the outdoor unit No. 1.
Turning other units ON besides unit No. 1 damages the control board.
