ELECTRICAL WIRING
27
NOTES
:
1. Follow local codes and regulations when selecting
field wires.
2. The above wire sizes marked with
n
are selected
at the maximum current of the unit according to the
European Standard, EN60 335-1. Use the wires
which are not lighter than the ordinary
polychloroprene sheathed flexible cord (code
designation H05RN-F).
3. The above wire sizes marked with
o
are selected
at the maximum current of the unit according to the
wire, MLFC (Flame Retardant Polyflex Wire)
manufactured by HITACHI Cable Ltd. Japan.
4. Use a shielded cable for the transmitting circuit
and connect it to the ground.
5. In the case that the power cables are connected in
series, add each unit maximum current and select
wires below.
6. The earth cable size complied with local code: IEC
245, No. 571.

CAUTION:
Use shielded wires for transmission wires between
the indoor and the outdoor units, and connect the
shielded part to the earth screw in the electrical box
of the indoor unit as shown below.
