7.4 List of Periodic Replacement Parts
Each part of the inverter has its own service life that will vary according to the environmental and operating
conditions. It is recommended that the following parts be replaced at the specified intervals indicated in Table 7.4-1.
When the replacement is necessary, consult your Fuji Electric representative.

Check “7.4.1 Judgment on service life” for
details.
(Note 1) The estimated life expectancy is calculated based on the following conditions for each inverter
specification. In environments with an ambient temperature above 40 °C or a large amount of dust or dirt,
the standard replacement interval may be shorter.
HHD specification: Inverter ambient temperature: 40°C, load factor: 100%
HND specification: Inverter ambient temperature: 40°C, load factor: 80%
Pay attention to the following items.
(1) The replacement intervals listed above are a guide for almost preventing parts from failure if those parts are
replaced with new ones at the intervals. They do not guarantee the completely fault-free operation.
(2) Table 7.4-1 does not apply to unused spare parts being kept in storage.
It applies only when they are stored under the temporary and long-term storage conditions given in Chapter 1
“1.3.2 Storage environment” and energized approximately once a year.
(3) Cooling fans and waterproof gaskets can be replaced by users. For details, refer to the maintenance related
documents. As for other parts, only the persons who have finished the Fuji Electric training course can
replace them. For the purchase of spare cooling fans and the request for replacement of other parts, contact
the sales agent where you purchased the product or your nearest Fuji Electric representative.
