Chapter 1 Safety Information and Precautions
- 11 -
10. Altitude and de-rating
In places where the altitude is above 1000 m, the cooling effect reduces due to thin air, and it is necessary to
de-rate the AC drive. You can contact Inovance for the de-rating details.
11. Some special usages
If your installation requires special cabling that this user manual does not describe, for example to support a
common DC bus, contact Inovance for technical support and advice.
12. Disposal
If it becomes necessary to dispose of any part of the AC drive system, DO NOT attempt to burn the parts on
a re. If you do, the electrolytic capacitors might explode, and the plastic components will create poisonous
gases. Treat any parts for disposal as ordinary industrial waste.
13. Adaptable motor
•
The standard adaptable motor is an adaptable four-pole squirrel cage asynchronous induction motor. For
other types of motor, select the correct AC drive according to the rated motor current.
•
The cooling fan and rotor shaft of non-variable-frequency motors are coaxial, which results in reduced
cooling effect when the motor speed reduces. Therefore, add a more powerful fan or fit a variable-
frequency motor in applications where the motor overheats easily.
•
The standard parameters of the adaptable motor have already been configured inside the AC drive.
However, it is still necessary to perform motor auto-tuning or to modify the default values based on actual
conditions. Otherwise, the running result and protection performance will be adversely affected
•
The AC drive might cause an alarm or might be damaged when a short-circuit exists on cables or inside
the motor. Therefore, perform insulation short-circuit test when the motor and cables are newly installed
or during routine maintenance. During the test, disconnect the drive from the tested parts.
