X. Care & Maintenance, Fault Information and
Troubleshooting
Periodical maintenances and inspections will keep your inverter in its normal
state for long time.
1. Precautions about Inspection and Maintenance
● Be sure to turn off the power supply to the inverter (R.S.T) first before the
inspection and maintenance.
● Af ter confirming the main circuit power supply has been turned off and
the display has disappeared, wait until the internal indicator lamp for high
voltage goes out before performing the inspection and maintenance.
● During the inspection, do not pull out or wrongly distribute the internal
power supply, wires and cables. Otherwise it will cause malf unction or
damage to the inverter.
● Do not leave any screw or other part inside the inverter during the
installation, or it will result in the short circuit of circuit board.
● Keep the inverter clean, f ree f rom dust, oil mist and moisture af ter the
installation.
2. Periodical Inspection and Maintenance items
● Check whether the power supply voltage conforms to the rated voltage of
the inverter.
(Pay special attention to that whether there is any damage on the power
supply wires and the motor.)
● Check whether the wiring terminals and the connectors are tight
(Check whether the power supply wires and terminal connection wires have
any broken strand).
● Check whether there is dust, iron filings or corrosive fluid in the inverter.
● Measuring the insulation impedance of the inverter is forbidden.
● Examine the output voltage, output current and output f requency of the
inverter.
(The measuring results should not have too big difference.)
● Check whether the ambient temperature of the inverter is between -5 ℃ and
40 ℃ and whether the installation environment has good ventilation.
● Check whether the humidity is kept below 90% (without condensation).
● Check whether the motor makes unusual noises or abnormal vibration in
running.
(The inverter should not be installed in a place with high vibration.)
● Please make periodical cleaning of vent holes.
