PM856K01 Relay input module

 Disconnect the AC input power of the frequency converter when the equipment is stopped normally

When the equipment shuts down normally, many users are accustomed to disconnecting the AC input power switch of the frequency converter, believing that it is safer and can also save energy.

Disadvantage: This approach seems to have the effect of protecting the frequency converter from power failure on the surface. In fact, if the frequency converter is not charged for a long time, combined with the influence of on-site environmental humidity, it will cause the internal circuit board to become damp and slowly oxidize, gradually leading to short circuits. This is the reason why soft faults are frequently reported when the frequency converter is powered off and shut down for a period of time before being powered on again.

Response strategy: In addition to equipment maintenance, the frequency converter should be kept in a live state for a long time. In addition, the upper and lower fans of the variable frequency control cabinet should be turned on, desiccants should be placed inside the cabinet, or automatic temperature and humidity control heaters should be installed to maintain ventilation and a dry environment.
