6.3 Regular Replacement for Some Components
Items
The corresponding
period for
replacement
Description
Cooling fan
2 years
For the axle of a fan, the standard lifetime is about 10~35
thousand hours. With reference to the time of 24 hours one day,
it is sure that the fan should be replaced every 2 years.
Filter
capacitor
5 years
The filter capacitor is an electrolytic capacitor, and will
deteriorate with time. The deterioration speed is contingent on
the ambient conditions. Generally, it shall be replaced every 5
years.
Relay
---
If bad contact occurs, please replace it immediately.
Note: Please send the inverters to the factory when replacement of the parts is necessary.
6.4 Inverter Insulation Resistance Measurement
1. Before measurement, first dismount the ‘wiring of the main-circuit
Terminals’ and the ‘control board’. Then execute wiring in the way as
the right figure.
2. The measurement is only suitable for the main circuit. Such
measurement is prohibited for control board terminals.
3. The value of the insulation resistance shall be greater than 5MΩ.
Note: Please do not carry out a high-voltage test, because the built-in semiconductor components will be
damaged by such a test.
6.5 Motor insulation resistance measurement
1.
Before measurement, please dismount the motor, and demonstrate
wiring as
the right figure.
2.
The insulation resistance shall be greater than 5MΩ.
