WARNING
Danger from automatic
startup of fan following a
power failure.
The MVE 10 reacts to over-
heating, e.g. caused by
over-voltage.
In the case of work including
installation, cleaning,
maintenance and repair work
in the danger area of the fan,
the fan should additionally be
separated from the mains
power supply.
7. Function/Operation
The MVE 10 protects the fan motor against
over-voltage/overheating. If the permitted
temperature in the motor winding (TK thermal
contact control circuit) is exceeded, the
MVE motor winding drops out and separates
the motor from the mains power supply.
Procedure in the case of a triggered main
contactor
After the motor winding has cooled down,
which can take up to 30 minutes depending
on the fan, a restart interlock in the MVE10
prevents the automatic switch-on of the
motor.
In order to trigger a restart, first press the red
button “0” and then the black button “1” so
that button “1” locks into place.
If the fan is switched back on before the
motor has cooled down, the MVE 10 is
triggered again within 60 seconds.

11.1 Mounting instructions
●
Only install unit on a dry, level surface. Any
installation position can be selected.
●
Only operate the unit when it is completely
installed.
●
Only connect unit to a permanently wired
electrical installation.
●
The unit may only be operated using the
voltage and frequency shown on the rating
