●
Use an ELB (Electric Leakage Breaker). If not used, it will cause an electric shock or a
fire.
● Do not operate the system until all the check points have been cleared.
(A) Check to ensure that the insulation resistance is more than 2 megohm, by measuring the
resistance between ground and the terminal of the electrical parts. If not, do not operate the
system until the electrical leakage is found and repaired.
(B) Check to ensure that the stop valves of the outdoor unit are fully opened and then start the
system.

NOTES:
1) Follow local codes and regulations when selecting field wires, and all the above are the minimum size.
2) The wire sizes marked in the table are selected at the maximus 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 H07RN-F) .
When connecting the terminal block using flexible cord, make sure to use the round crimp-style terminal
for connection to the power supply terminal block.
Place the round crimp-style terminals on the wires up to the covered
part and secure in place.
When connecting the terminal block using a single core
wire, be sure to perform curing.
3) When transmitting cable length is more than 15 meters, a larger wire size should be selected.
4) Use a shielded cable for the transmitting circuit and connect it to ground .
5) In the case that power cables are connected in series, add each unit maximum current and select
wires below.
*In the case that current exceeds 63A, do not connect cables in series.
