6.1 Outline
CAUTION
Neither disconnect and reconnect each cable while the pump is running.
Particularly for unplugging the control cable from the receptacle, check complete shutdown of
the pump by ROTATION lamp goes out and, thereafter, turn off the POWER switch.
CAUTION
Do not turn the power off while the pump is running. The touch-down bearing may need to be
replaced if the power is turned off repeatedly during operation.
If the power is turned off during rotation, power from regenerative braking will keep the rotor
levitated. After slowing down, levitation stops and the rotor is supported by the touchdown
bearing. Therefore, repeated touchdowns will reduce the life of the bearing.
6.1.1 Introduction
Please operate by the Power Supply Unit. For more information regarding an operation, please
refer to the Power Supply Unit Instruction Manual.
