Warning: This inspection should only be performed by qualified and well-trained personnel. Ensure that the machine has stopped and is disconnected from the power supply, including accessory devices such as space heaters and brakes, before any servicing is undertaken.

Visual inspection of the motor and coupling. Check for abnormal noises, vibrations, excessive heating, wear signs, misalignment, or damaged parts.

Measure the insulation resistance according to item 5.4.

Clean the motor enclosure. Remove oil spills and dust accumulation from the motor frame surface to ensure better heat transfer to the surrounding ambient.

Check cooling fan condition and clean the air inlet and outlet openings to ensure free airflow over the motor.

Investigate the seal condition and replace them if required.

Drain the condensed water from inside the motor. After draining, reinstall the drain plugs to ensure the degree of protection as indicated on the motor nameplate.

Check the connections of the power supply cables, ensuring the correct clearance distance between live and grounded parts, as specified in Table 6.3.
