o
Ensure the colour of wires of outdoor unit and the terminal Nos. are the same to the indoor unit’s
respectively.
o
Earth wire shall be longer than the other wires as shown in the figure for the electrical safety in case of
the slipping out of the cord from the Holder (Clamper).
2 Cable connection to the power supply through isolating device (Disconnecting means).
o
Isolating device (Disconnecting means) should have minimum 3.0 mm contact gap.
o
Connect the approved polychloroprene sheathed power supply 1 cord (5 x min 1.5 mm
2
