IPM module
temperature of
the inverter
compressor
°C
●The IPM module temperature i
s lower
than 80°C, and the highest temperature
does not exceed 95°C.

Bus voltage of
the inverter
compressor
driver
V
●The normal bus voltage is 1.414 times
of the power voltage. For example, if
the voltage of a three-phase power is
390 V, the rectified bus voltage is: 390
V x 1.414 = 551 V. Difference between
the measured value and the above
calculated value within 15 V is normal.

°C
●Based on the ambient temperature,
the inlet pipe temperature of the same
indoor unit in cooling mode is 1°C to
7°C lower than the outlet pipe
temperature;
●In heating mode, the inlet pipe
temperature of the same indoor unit is
