MDS-EX-CVP Series Specifications and Instruction Manual

11. Appx.1: Maintenance

Periodic inspection of the following items is recommended.

[1] Are any of the screws on the terminal block loose? If loose, tighten them.

[2] Are any of the cables damaged or cracked? If the cables move with the machine, periodically inspect the cables

according to the working conditions.

A guide to the part replacement cycle is shown below. Note that these will differ according to the working conditions or

environmental conditions, so replace the parts if any abnormality is found. Contact Mitsubishi branch or your dealer for

repairs or part replacements.

Part name

MDS-EX-CVP

[1] Power smoothing capacitor:

The characteristics of the power smoothing capacitor will deteriorate due to the effect of ripple currents, etc. The

capacitor life is greatly affected by the ambient temperature and working conditions. However, when used

continuously in a normal air-conditioned environment (ambient temperature is an average of 40 °C or less), the

service life will be ten years.

[2] Relays:

Contact faults will occur due to contact wear caused by the switching current. The service life will be reached

after 100,000 cumulative switches (switching life) although this will differ according to the power capacity.
