3.3 CAUTIONS ON COMPRESSOR DRIVE REPLACEMENT
(1) Disconnect the power supply of the system. Set a multimeter to the AC voltage gear and
measure voltage between two of the lines (L1, L2, L3, and N). The measuring result should be 0 V
(sometimes, multimeters may be faulty and read false values). Set a mark beside the power supply for
warning.
(2) Measure compressor drive DC bus voltage between two wire terminals of P, U, V, W and N. Set
the multimeter to the DC voltage gear and measure the voltage between P and N. The voltage should be
lower than 36 V. If no multimeter is available, wait for 20 minutes before performing the steps below.
