● the DC supply and motor cables comply with the requirements given in Chapter 3.

● the control cables are located as far as possible from the power cables (see

Chapter 2) and the shields of the shielded cables are connected to protective ground.

The wires may not touch the electrical components of the inverter.

● the common inputs of digital input groups are connected to +24V or ground of the

I/O terminal or the external supply.

3. Check the quality and quantity of cooling air. (See Chapter 2, Mounting Space

Dimensions.)

4. Check the inside of the inverter for condensation.

● motor nominal voltage

● motor nominal frequency

● motor nominal speed

● motor nominal current

You will ﬁnd the values needed for the parameters on the motor rating plate.

8. Perform run test without motor

Perform either Test A or Test B:

Test A — Controls from the I/O terminals:
