7-2 About Recommended Replacement Parts
For a longer use of the power supply, we recommend periodical overhauls.
See Table 7-1 which shows the recommended replacement parts.
For an overhaul, be sure to contact us.
If you or a manufacturer other than us replaces the parts without our permission, the repair cost shall be
borne by you based on our free-of-charge repair terms and conditions (P.V.) regardless of the remaining
warranty period.

1. The recommended replacement years do not guarantee parts life. The deterioration rate of these
parts greatly depends on the frequency in use and environment of the unit at your site.
2. Especially the life of a power semiconductor depends on the difference in the operating condition.
A high working environment temperature, frequent ON/OFF cycles, and operation around the
rating shortens the life.
3. The life of an electrolytic capacitor is shortened if the working environment temperature is high.
4. The life of a mechanically operating part (such as a contactor) is decided by the number of times
how many it is operated and, if it is frequently operated, the life is shortened.
5. The periodical maintenance parts assume a general case. Since even other parts may need to be
maintained and replaced depending on the state of your working environment and input equipment,
contact us.
6. If the product is stored without energization for a long time, the internal elements may deteriorate for
a shorter period of time than the recommended replacement terms above.
