Interfaces 8.2 Electrical connections

The cables for the power connection are brought out at the front of the stator (B side). The open cable ends must be connected in a terminal box, which must be provided by the machine manufacturer. Sufficient installation space must be provided in the axes construction. Standard MOTION–CONNECT cables, which are available with the standard range of accessories for the drive system, can be used from this EMC-compliant terminal box (minimum degree of protection: IP54).

For information on connecting the power, please also refer to the figures relating to system integration in the section titled "System requirements". The rotor rotates clockwise if the torque motor is connected to phase sequence U, V, W. Also refer to "Direction of rotation" in Chapter "Technical features".

8.2.2Signal connection

The temperature monitoring circuits must not be connected without a protection module.

DANGER

Electrical shock hazard!

The circuits of Temp–S and Temp–F do not have safety isolation with respect to the power circuits according to the specifications for safety isolation in compliance with EN 61800-5-1 (previously, safety isolation according to EN 50178 (VDE 0160)).

Connecting the temperature monitoring circuits to the SMC20 Sensor Module does not fulfill the requirements of protective separation to EN 61800-5-1. The temperature monitoring circuits must be connected via the SME12x.
