â– 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.
14. 2. 3 How to replace the battery
1 Remove the operation panel from the inverter. Refer to [10.
3. 8]
2 Open the slot cover at bottom (left side) of operation panel
3 Eject the battery by using insulated tool (to avoid short-circuit
by remaining charge)
For disposal of battery, see [16]
4 Insert new battery, at that time take care the polarity.
5 Close the slot cover
Then, clock setting is needed, because the clock is not kept by replacing the battery
Refer to E6582110 for setting.
Part name
Standard replacement cycle
*1
*1 The replacement cycles greatly vary depending on the operating environment.
Replacement method
Relays - To be determined by inspection
Aluminum electrolytic capacitor on
the printed circuit board
10 years
*2
*2 It is based on the case where the inverter output current is 80% of the inverter rated current.
Replace with a new one. (To be
determined by inspection)
Battery CR2032
*3
(used in the
operation panel)
*3 Use CR2032EC (Toshiba).
The remaining capacity of the
battery is indicated into the LCD
screen with icons (see 3. 1. 2)
Replace with a new one.
