DL100 Series Universal Low-Power Inverter
2.2 Wiring
1. Wire diameter shall be selected according to applicable electric code, and
wiring shall be done by qualified technicians.
2. Wiring shall not be started unless the power supply of the inverter is
completely disconnected.
3. The grounding terminal of the inverter must be reliably grounded; otherwise,
there can be a danger of electric shock.
4. Before wiring, make sure the power supply has been disconnected for over 10minutes;
otherwise,theremay be a danger ofelectric shock.
5. The electronic elements in the inverter is quite sensitive to static electricity,
hence no foreign articles shall be placed into the inverter or contact the main
board.
2.3 Maintenance
3．Precautions of use
In this manual, the wordings of “Tip” and “Attention” are defined as below:
1. The inverter shall be installed in the place with good ventilation.
2. The motor’s temperature can be a little higher than that of industrial frequency
power during operation of the inverter, which is abnormal.
3. With long-term operation at low speed, the operation life of motor can be
affected due to the poorer heat dissipation effect. In this case,special frequency
converter shall be selected or the motor’s load shall be decreased.
4. When the altitude is over 1000m, the inverter shall be derated. Increase of
altitude for every 1500 m shall be ground for derating by 10%.
Tip: To give some useful information.
Attention: To indicate any precautions during operation.
Wiring, inspection and other maintenance work shall not be
done until the power supply is disconnected for 10 minutes.
No alternating current power supply is allowed to be connected
onto the U, V, and W of the inverter.
