Install the disconnect device with a contact gap of at least 3mm in all poles nearby the units (Both indoor unit and outdoor unit).The appliance must be positioned so that the plug is accessible.

The specifications of the breaker and power cable listed in the table above are determined based on the maximum power (maximum amps) of the unit.

The specifications of the power cable listed in the table above are applied to the conduit-guarded multi-wire copper cable (like, YJV copper cable, consisting of PE insulated wires and a PVC cable jacket) used at 40°С and resistible to 90°С (see IEC 60364-5-52). If the working condition changes, they should be modified according to the related national standard.
