*1 Refer to the NOTES for selection of the power source cable size.
NOTES:
1) Follow local codes and regulations when selecting field wires.
2)
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).
3)
Use a shielded cable for the transmitting circuit and connect it to ground.
4) In the case that power cables are connected in series, add each unit maximum current and select wires below.
Selection According to EN60335-1
5) Run through the cables using conduit tube,and Completely seal the end of conduit tube with sealing materials.
*2 : In the case that current exceeds 63A,Don't series connection
Keep a distance between
each wiring terminal and
attach insulation tape or
sleeve as shown in the figure.
Correct
Insulation Tape or Sleeve
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.

Wiring Method with Clamp
1. Insert the wires by into the
cord clamp and clamp them
as shown in the figure.
2. Perform wiring so that wires
do not touch the compressor,
refrigerant pipes or edge of
the covers.
Make a loop of the wires so that disconnecting
the wirings for replacing parts is not required.
CAUTION:
When using conduit, do NOT lead it in the outdoor
unit. If the conduit wiring touches the compressor
and refrigerant cycle in the outdoor unit, it may
cause to damage them.
