1. Turn OFF the power supply.
2. Measure the resistance between phases of U, V, W at the motor side connectors (3-core wire)
to check that the values are balanced and there is no short circuiting, while connector or relay
connector is disconnected.
FXSQ54TB, FXMQ15-54PB, FXMQ30-54TB
Remove the X1A connector from the fan PCB (A2P) and measure the resistance between the U
and V, V and W, and W and U phases of the motor connector (with five conductors) and check that
each phase are balanced (within a permissible dispersion range of ±20%).
