Periodic Maintenance Of Parts; Precautions When Replacing The Control Board (1Pcb) - YASKAWA CIMR-ACA4011 Instruction Manual

Periodic Maintenance of Parts

The MxC is configured of various components, all of which must be operating properly in order to take full
advantage of the MxC functions.
Some electrical components will require maintenance depending on storage conditions and how the MxC is
used. In order to keep the MxC operating normally over a long period of time, it is necessary to perform period
inspections and replace parts according to their service life.
Periodic inspection standards will vary depending the installation environment and usage conditions. Recom-
mended maintenance periods are noted below. Keep them as reference.
To replace the cooling fan, follow the Cooling Fan Replacement on page 8-4. To replace other parts, contact
your Yaskawa representatives for technical maintenance.
