Fig. 6.3 Wiring Connection of Outdoor Unit
Keep a distance between
each wiring terminal and
attach insulation tape or
sleeve as shown in the figure.
Insulation Tape or Sleeve
Correct
Incorrect
Do not use a solderless
terminal when
a single wire is used.
If used it causes
abnormal heating at
the caulking portion
of the terminal.
If a single wire is used
connect the
wire direct as shown
in the figure.
Make a loop of the wires so that disconnecting
the wirings for replacing parts is not required.
CAUTION:
Piping Cover
Conduit
Power Supply Cable
When using conduit, do NOT lead it in the outdoor

NOTES:
1) Follow local codes and regulations when selecting field wires.
2)
3)
4) In the case that power cables are connected in series, add each unit maximum current and select wires below.
*2 : In the case that current exceeds 63A,Don't series connection
The wire sizes marked with *1 in the above table are selected at the maximum current of the unit according to
the European Standard, EN60335-1.Use the wires which are not lighter than the ordinary polychloroprene sheathed
flexible cord (code designation H05RN-F).
5) Run through the cables using conduit tube,and Completely seal the end of conduit tube with sealing materials.
