To ensure long service life and smooth operation of the drive, carry out the following checks at regular
intervals. Always isolate the drive from the power supply and make certain the keypad is off before
proceeding.
1- Remove the dust that collects on the cooling fans and on the control circuit board, preferably by means
of compressed air or using a vacuum cleaner.
2- Check that there are no screws loose at the power or control terminals.
3- Check that inverter function is <<normal>> and there is no abnormal overheating.
7.1 MEGGER TEST
When performing insulation tests using a Megger tester
on the input/output cables or on the motor, remove all
the connections to all terminals of the drive and perform
the test only on the power circuit, in accordance with
the adjacent diagram.
Do not Megger test the control circuits.
