MIDA WARNING The degree of protection of the device is only ensured if, at the end of the installation, the cover screws and the cable glands have been properly tightened. Close the holes of unused cable glands with the appropriate plugs. Protect the device from direct exposure to weather and sunlight. - Page 15 MIDA In size 2 devices, the ground connection between the base and the power is made by means of four metal pins on the power side that engage into four special holes on the base with spring contacts. At the same time, these metal pins serve as a guide for a correct coupling between the base and the heat sink.
-
Page 16: Assembly On-Board The Motor
MIDA DANGER Be careful not to damage or remove the four metal pins, as this will not only compromise the mechanical coupling between the base and the power, but also the ground connection. 6.4. Assembly on-board the motor The device may be installed in place of the motor terminal box cover both horizontally and vertically. It is necessary to check with the motor manufacturer whether the base of the device can be fastened to the motor casing. - Page 17 MIDA On-board motor installation for size 1 devices P.E.

The pump is restarted only after the measured value has dropped below the maximum alarm value for more than 5 seconds.
- Page 35 MIDA Parameter Default Description Control ramp Time in which the device decreases the motor power frequen- cy from the minimum control frequency (Frequency min con- t = XX [s] trol) to the minimum motor frequency (Min motor frequency). If during this time the measured value falls below Set value - Delta control, the device restarts the motor.
