▪ Close additional open cable entries, using O-rings or suitable gaskets.
▪ Observe prescribed tightening torques for cable glands and other screws/bolts.
▪ When retrofitting cable glands to safeguard the required level of enclosure
protection, ensure that the gasket is seated properly on the outside of the
terminal box.
Connecting the motor
1. Check the electrical voltage of the available power supply network against the
data on the motor name plate.
2. Connect the earth conductor (PE).
3. Knock out any knock-out openings in the terminal box. While doing this, avoid
causing damage to the terminal board, cable connections, etc. inside the
terminal box.
4. Connect the motor in star configuration or delta configuration in accordance
with the rated voltage (see name plate) and the available power supply
network. Alternatively, the 6-core connection of the three windings can be
connected to an external switchgear for automatic switchover.
