7.3 Replacement of Vulnerable Parts
The cooling fan of the braking unit is a vulnerable component part. Its service life is closely
related to the usage environment and maintenance.
You can determine whether to replace the cooling fan based on its running conditions.
The service life of the two components is shown as follows:
Bearing worn
Blade aging
Check whether there is crack on the
blade.
Check whether there is abnormal
vibration noise upon startup.
7.4 Storage of the Braking Unit
For storage of the braking unit, pay attention to the following two aspects:
Pack the braking unit with the original packing box provided by Inovance.
Long-term storage will degrade the electrolytic capacitor. Thus, the braking unit must be
energized once every 2 years, each time lasting at least 5 hours. The input voltage must
be increased slowly to the rated value with the regulator.
