Note 1 Measurement conditions are as follows.
Outside air temperature: 32°C, evaporation temperature: -10°C, suction superheat: 10 K
Inverter compressor operating frequency: 66 Hz (ECOV-X37VA), 95 Hz (ECOV-X55VA)
Note 2 The figures in the angle brackets in the "Electric wire size" row indicate the maximum wire length where the voltage drop is 2 V
or less.
Note 3 Specific wiring requirements should adhere to the wiring regulations of the region.
Power supply cords of appliances shall not be lighter than polychloroprene sheathed flexible cord (design 60245
Note 4
IEC57).
Note 5 An earth leakage breaker with at least 3 mm contact separation in each pole shall be provided by the installer.
Leaked current varies depending on wire length, wire routing, and/or presence of devices that emit high frequency.
Select high-harmonic-type earth leakage breakers.
Note 6 Do not use a phase-advancing capacitor with inverter compressor.
®
If MODBUS is used, follow the instructions below.
• Do not connect a power supply to the terminal block for transmission lines. If connected, the electronic parts will burn out.
• Use shielded cables for transmission wiring.
Wiring using a multi-core cable with different types of transmission wires compromises correct transmission of signals and
results in a malfunction.
• When splicing transmission wires, make sure to splice the shielded cables as well.
For details, refer to section 10-6.
