10.5 Common

● 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 1 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.
● Pay attention to the following items while the system is running.
(A) Do not touch any of the parts by hand at the discharge gas side, since the compressor
chamber and the pipes at the discharge side are heated higher than 90℃.
(B) DO NOT PUSH THE BUTTON OF THE MAGNETIC SWITCH(ES). It will cause a serious
Accident.
NOTES:
1) Follow local codes and regulations when selecting field wires.
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 tough rubber
sheathed flexible cord (code designation H05RN-F) or 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.
*in the case that current exceeds 63A, do not connect cables in series.
