In Case Of A Failure; Cautions For Storage; Standard Replacement Cycle Of The Other Principal Parts - Toshiba TOSVERT VF-AS3 Instruction Manual

For replacement of the smoothing aluminum electrolytic capacitor, contact your Toshiba distributor.
The inverter unit may need to be replaced depending on the capacity because the smoothing alumi-
num electrolytic capacitor is mounted on the printed circuit board.
Memo

■ Standard replacement cycle of the other principal parts

The estimated parts replacement cycles are shown in the following figure. They are based on the
assumption that they will be used under normal use conditions (average ambient temperature of
40°C, load factor of 80% or less, 24-hour operation per day, with no corrosive gas, oil mist, dust,
metal powder, etc. present). These replacement cycles are not the lives of the parts. They are based
on the assumption that more parts will become abnormal when they are used over these cycles.

*1 The replacement cycles greatly vary depending on the operating environment.
*2 It is based on the case where the inverter output current is 80% of the inverter rated current.

14. 3 In case of a failure

Should a failure occurs, contact your Toshiba distributor. Before contact, check the information on the
name plate attached on the right side of the inverter unit, and presence or absence of the optional parts to
inform the distributor of them as well as inverter problems.

14. 4 Cautions for storage

14. Maintenance and inspection
• You can check the parts replacement alarm and output signals in [Monitor mode].
• The design life expectancy of the smoothing aluminum electrolytic capacitor becomes shorter
at high ambient temperature, and becomes longer at low ambient temperature.
Part name
Storage location
Avoid a location with high temperature, high humidity, or lots of dust or metal powder for stor-
age. Store the inverter in a well-ventilated location (storage temperature: -25 to +70°C).
Periodical check
When you store the inverter for two years or more, refer to [14. 2. 2], and energize it for five
hours or more once every two years.
