CAUTION
● Please select power source for indoor unit and outdoor unit
respectively.
● The power supply has specified branch circuit with leakage
protector and manual switch.
● Outdoor unit and indoor unit conncet with required power
supply which is 220-240V~ 50Hz or 380-415V 3N~ 50Hz.
● Use 3-core screened wire as indoor and outdoor control wire.
● The installation should comply with relevant national electric
standard.
● Power wiring should be engaged by specialized electrician.
CAUTION
CEquipment complying with IEC 61000-3-12.
● A disconnection device having an air gap contact separation in
all active conductors should be incorporated in the fixed wiring
according to the National Wiring Regulation.
●
The reserved function is indicated in broken line table, users
can select it when necessary.
To prevent interference with communication, increase a magnetic
ring inside and outside communication line (around 1 lap).

CAUTION
● When power cord is parallel with signal wire, please put them
into separate wire distribution pipes, and leave a proper
distance.
● (Reference distance: It is 300mm when current capacity of
power cord is less than 10A, or 500mm when 50A).
2) Indoor/Outdoor Unit Signal Wire
Wrong connection may cause malfunction.
3) Wiring Connection
Seal the wiring connection with the insulation material , or
the condensing dew will be caused.
