CAUTION
For a 3-phase cooling fan, when the phase sequence of the 3-phase power supply is connected reversely, its cooling
capacity degrades due to the reversed rotation direction. Make sure the air blowoff direction.
When the fan rotates reversely, reconnect BU and BW reversely, and then check the blowoff direction.
