Replacing components

5.2.1

Replacing the fan assembly

The fan assembly consists of:
• the fan housing
• a fan
• the starting capacitor,
The fan is mounted for
♦ between the capacitors and the motor connection for types
of construction E to G
♦ below the line supply- and DC link circuit connection for
type of construction H.
• Remove connector X20
• Remove the cable ties
• Release the screw connections
• Remove the fan assembly towards the front
• Install the new fan assembly in the inverse sequence
• Before commissioning the drive check that the fan can run freely and check the airflow direction. The air
must be blown upwards out of the unit.
5.2.2

Replacing the fan transformer

The fan transformer is mounted behind the motor connection.
• Mark the transformer connecting cables and disconnect them.
• Release the screw connections at the bottom on the transformer mounting panel and remove the transformer.
• Install a new fan transformer in the inverse sequence
5.2.3

Replacing the starting capacitor

The starting capacitor is mounted next to the fan connection.
• Remove the plug connections from the starting capacitor
• Unbolt the starting capacitor
• Install a new starting capacitor in the inverse sequence
5-2
The fan may only replaced by qualified personnel.
The drive converters are still at hazardous voltage levels up to 5 min. after the
unit has been powered-down as a result of the DC link capacitors.
If these warnings are not observed, death, severe bodily injury or considerable
material damage could occur.
