9) Service beyond the rated voltage
The frequency converter shall not be beyond the allowable working voltage, the components of the
frequency converter may be damaged. If necessary, the related boost device or dropping device shall be
used for the voltage transformation of power supply before input into the frequency converter.
10) Change three-phase input into two-phase input
It is not allowed to change three-phase frequency converter into two-phase service, or else, the failure
or any damage to the frequency converter may occur.
11) Lightning impulse protection
The lightning overcurrent protection device is set in the frequency converter so that the frequency
converter has certain self-lightning proection capability, but the user shall set a lightning protection
device in front of the frequency converter at the point with much lightning.
12)Altitude and derating
In a region with altitude more than 1,000m, the frequency converter will have bad heat dissipation
effect resulting from thin air. The derating will be required if necessary. Please contact use for technical
consultation in respect of this situation.
13) Some special purposes
If the user has to use the method beyond the wiring diagram as specified in this manual, e.g. DC bus,
please contact us for consulting.
14) Notes in the scrapping of frequency converter
Electrolytic capacitor in the main loop and electrolytic capacitor on the printed board may result in
explosion in case of burning. The plastic parts in burning may generate poisonous gas. Please dispose
the plastic parts as industrial reuse.
15)About adaptive motor
● The standard adaptive motor is four-pole cage asynchronous induction motor. If it is not the said
motor, please select the frequency converter according to the rated current of the motor.
● For non-variable frequency motor, cooling fan and rotor spindle are in coaxial connection. The
cooling effect of fan will be weakened as the rotating speed is reduced, as a result, the exhaust fan
