6.2 Operation of the motor with low voltage release (only MA II)
Motors of type MA II are optionally equipped with low voltage release and do not start automatically again
after interruption of power supply. On networks with large voltage fluctuations, the low voltage release
can prevent the motor from being switched on.

The on/off switch must be actuated again in order to restart the motor.
6.3 Operation of the motor without low voltage release
!
WARNING
Danger of injury due to uncontrolled restarting of the motor after interruption in the power
supply!
►
On/off switch must be set to "0".

Restart the motor again.
6.4 Operation of the motor with electronic speed controller
(only MI 4-230 E, MI 4-120 E, MI 4-100 E)
!
WARNING
Danger of injury due to uncontrolled restarting of the motor!
►
Do not stop the motor by using the speed controller.
Motors of type MI 4 are available with an electronic speed controller with which the flow rate can be
adjusted as required. The flow rate at minimum speed depends on the respective mains supply. At a free
discharge it corresponds to approx. 40% of the maximum flow rate.
►
Flow rate can be adjusted as required by turning the rotary handle (
