2
or 6.0 mm flexible cord, type designation 60245 IEC 57 or heavier cord.
Ensure the colour of wires of outdoor unit and the terminal no. are the same to the indoor unit's
o
respectively.
Earth wire shall be longer than the other wires as shown in the figure for the electrical safety in case of
o
the slipping out of the cord from the Holder (Clamper).
2 An isolating device must be connected to the power supply cable.
Isolating device (Disconnecting means) should have minimum 3.0 mm contact gap.
o
Connect the approved polychloroprene sheathed power supply 1 cord (3 x 4.0 or 6.0 mm
o
supply 2 cord (3 x 4.0 mm
and to the other end of the cord to isolating device (Disconnecting means).
3 To avoid the cable and cord being damaged by sharp edges, the cable and cord must be passed through a
bushing (located at the bottom of indoor unit) before being connected to the terminal block. The bushing must
be used and must not be removed.
