Check to ensure that the voltage of power supply is within 10% of nominal voltage and earth phase is
•
contained in the power supply wires. If not, electrical parts will be damaged.
•
Check to ensure that the capacity of power supply is enough. If not, the compressor will not be able to
operate because of abnormal voltage drop at starting.
•
Check to ensure that the earth wire is connected.
•
Install a main switch, multi-pole main switch with a space of 1.38 inch (3.5mm) or more, single phase
main switch with a space of 1.18 inch (3.0mm) or more between phases.
Check to ensure that the electrical resistance is more than 2MΩ, 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.

Max Running Current (A): REFER TO NAMEPLATE
NOTES:
•
The ground wire must be longer than the current-carrying conductor when installing the power cord.
•
The wiring specifications of the weak current communication loop should not be less than RVV(S)P
shielded wire or equivalent, the shielding layer needs to be grounded.
•
Using the air conditioner power terminal to transfer the power cord is strictly prohibited
•
Follow local codes and regulations when selecting field wires, and all the above are the minimum wire
size.
•
Power cord selection shall not be lighter than polychloroprene sheathed flexible cord (code
designation 60245 IEC 57), and the power cord should be copper wire.
•
The wire sizes marked with *1 in the above table are selected at the maximum current of the unit
according to IEC60335-1 Standard.
•
When transmission cable is longer than 49.2ft (15m), a larger wire size should be selected.
•
Install main switch and ELB for each system separately. Select the high response type ELB that is
acted within 0.1 second.
•
In the case that power cables are connected in series, add each unit maximum current and select
wires below.
