AM.8.1 POWER AND BRAKE CONNECTION

It is done through an internal terminal box.

* Power terminals.

* Internal thermal switch contacts (Klixon 150°C (302°F)).

* Brake contacts as an option.

There is internal thermal switch as a protection against overtemperature. It is a normally

closed contact that opens when the temperature exceeds 150°C (302°F). It has no polarity

and withstands up to 250V/2.5A. This contact should be included in the Emergency chain.

Make sure that the U, V, W and Ground terminals of the Drive Module are connected

to the U1, V1, W1 and Ground terminals of the Motor respectively. Otherwise, the motor

would not work properly.

For further information about the characteristics of the power supply cables for the

asynchronous motors as well as the selection criteria, see chapter IN.

To control the brake a single-phase mains (220 Vac) connection is needed.

The brake must be released when applying these 220 Vac. That way, in case of a power

outage, the motor will be braked.

The windings of the motor have a star connection (as shown here) and it

cannot be changed for any reason because it would make it run

improperly.
