Take note of all of the data of the converter manufacturer for said fault condition.
Motors with brake
The mains line in the version with incorporated brake is connected in the motor terminal box and in the version with
the built-on brake in the separate brake terminal box. Observe the supplied connection diagram and the rated volt-
age visible on the rating plate. In the presence of an AC connection the brake coil is energized by means of a silicon
rectifier accommodated inside the explosion-proof encapsulation.
>
The temperature sensors applied both in the motor and brake are to be connected as envisaged in
Section "Motors with temperature monitoring", page 13.
Motors with brake or tachometer mounted under the ventilator hood
In order to connect brakes or tachometers mounted under the motor ventilator hood, the latter must be disassem-
bled.
Unscrew any shock pulse sensors or regreasing devices. Loosen the fastening screws on the hood and remove the
hood from the motor.
Connect the brake of tachometer as per the attached circuit diagram and pass the cable along the shortest route
through the motor fins towards the main terminal box. It is recommended to insert a protective tube over the connec-
tion cable in the fin area to prevent wearing.
Fit the ventilator hood back on the motor and check the position of the boreholes for any shock pulse sensors and
regreasing devices. In the case of motors with an axial fan running into a nozzle, make sure that there is a uniform
air gap all around between the fan and nozzle. Secure the hood with the fastening hoods.
Check manually that the fan runs freely once the mounting is completely.
Motors with backstop
Motors with built-in backstop must be operated at a minimum rpm higher than the value specified on the rating plate
– e.g. FXM 850 min
–1
– to prevent excessively high temperatures.
