Check that the main power is switched off.

When installing a new unit, disconnect the motor (U / T1, V /

T2, W / T3) cables to prevent damage to the frequency

converter.

Measure the insulation resistance of the motor windings

(each phase to ground). Insulation resistance requirement for

new motor:

Cold motor (10..40 °C): ≥ 5 MΩ

Warm motor (40 °C or more): ≥ 1 MΩ

If insulation resistance is less that requirement the motor

shall be dried.

Reconnect the motor cables and check the thightness of the

other cables.

Check that the external connections and selected control

parameters (switches) are set according to the application.
