Summer:
This type of frequency converter is a special frequency converter developed by our company.It keeps the advantages of the original series products, simplifies the function of the outer terminal, and makes it cheap, compact, easy to operate, practical and high reliability,when in use, it needs to cooperate with the special operation panel.
Matters needing attention:
1、The frequency converter except the empty terminal, the circuit board, the external operator and the connection are all with strong electricity, the power must be cut off before installation, operation and maintenance.
2、The host must be installed in a closed case out of reach.
3、The frequency converter is best installed on a metal plate to facilitate heat dissipation
4、This frequency converter is only used in industrial three-phase induction motors, otherwise there may be financial damage.
5、The power input terminal shall be connected with contactor or air switch with the same capacity or above,In order to cut off the power supply immediately in case of emergency, otherwise there is the possibility of financial damage or fire.
6、Power input R, S end and frequency converter output U, V, W end must not be connected wrong, otherwise it will damage the frequency converter or cause a fire;
7、The output end of the frequency converter (U, V, W) is not allowed to connect with relay and compensation capacitor, otherwise the frequency converter will be damaged.
8、Wiring or maintenance operations must be carried out by electrician qualified personnel.Before maintenance inspection, the power supply should be cut off first, and the STANDBY LED indicator light should be completely off before it can be carried out, otherwise there may be electric shock.
9、When using output frequency above 60Hz, please fully confirm the safety of motor and load in advance.
