Chapter V Maintenance
5.1 Daily Inspection and Maintenance
Affected by environment temperature, humidity, vibration, and inverter internal component
aging, the inverter may suffer some potential problems during operation. In order to stably operate
the inverter for a long term, conduct periodical inspection once each year.
5.1.1 Requirements of Inspection and Maintenance
1. The inspection shall be conducted by professional technician. When necessary, cut off the
power supply of inverter.
2. Avoid leaving metal components and parts in inverter, or else it may damage the equipment.
3. The inverter has conducted electrical insulation experiment before leaving factory, so the
user needn’t conduct high-voltage insulation test.
4. If you intend to conduct insulation test on inverter, all input and output terminals must be
short circuit reliably. It is forbidden to conduct insulation test on single terminate. Please
use 500V megameter during test.
5. It is forbidden to use megameter to measure control loop.
6. When conducting insulation test on motor, remove the connecting line between motor and
inverter.
5.1.2 Key Points of Inspection and Maintenance
Please use the inverter under the environment recommended in the manual and conduct
inspection and maintenance according to the following table.
