Disconnect the power sources and en-
sure continuous disconnection during
maintenance of the drive and load.
If the variant has heatsinks attached, they must be
maintained for proper functionality. If the heatsinks
are covered in dust or any other materials, such as a
spider's web, the heatsink does not dissipate the heat
sufficiently.
To prevent this issue, frequently inspect the heatsinks
and clean or remove any material preventing airflow
from going through the fins of the heatsink.
