1.3.1 Pertaining to the inverter
1)
Capacitor or varistor used to improve power factor
Because of the PWM wave output, the capacitor used to improve power factor or the anti-thunder
varistor installed at the output side of the inverter would cause tripping fault or component damages.
Therefore, they must be removed. As shown in figure 1-2:
Figure 1-2 Capacitor prohibited at the output side of the inverter
2)
Use of switch devices such as contactor installed at the output side of the inverter
If switch devices such as contactor is to be installed between the inverter and the motor, make sure to
conduct on-off operation when the inverter has no output, otherwise the inverter may be damaged.
3)
Usage beyond the rated voltage range
The S610M series are not suitable for use beyond the permitted working voltage range. If required,
please use a corresponding step-up or step-down device for voltage transforming.
4)
Lightning surge protection
The inverter with a built-in lightning surge protection device has a certain ability of self-protection
against inductive lightning.
5)
The altitude and derating use
At the altitude of above 1,000 meters, the inverter needs derating use because thin air causes poor
cooling effect of inverter. The relation curve of altitude and rated current of the inverter is as shown in
figure 1-3.
