NOTES:
①
Selection of circuit breaker and power cord in the above table is based upon unit’s maximum
power (maximum current).
②
Specification of power cord is based on the working condition where ambient temperature is
40°C and multi-core copper cable (working temperature is 90°C, e.g. power cable with YJV
cross-linked copper, insulated PE and PVC sheath) is lying on the surface of slot. If working
condition changes, please adjust the specification according to national standard.
③
Specification of circuit breaker is based on the working condition where ambient temperature
of circuit breaker is 40°C. If working condition changes, please adjust the specification
according to national standard.
④
The communication wire between the indoor unit and the outdoor unit should wind with a
magnetic ring (packed in the packing accessories). The communication wire should wind the
magnetic ring for 4 circles, and the use the tie line to fix the magnetic ring at the meta sheet.
Please refer to the diagrammatic sketch as Fig.4.23(Only for the models whose packing
materials include magnetic ring):

4.5.3 Engineering Wiring of Power Supply and Communication Cable
(1) Please refer Fig.4.24 and 4.25for engineering wiring. If there is the hole for cable tie in wiring
route, please fix the wire with cable tie. Connect the power cord and communication cable to
the corresponding terminal board and grounding screw according to the wiring diagram.
(2) Please be noted that engineering wiring cannot touch the pipe and appliance.
(3) This figure is only applicable for engineering wiring reference of power supply and
communication cable. If there are differences between the figure structure and actual unit,
please refer to the actual unit.
(4) For engineering wiring, please refer to the wiring diagram provided with the unit.
