    Maintenance 8 Maintenance 8.1 Routine maintenance When you use this series you must assemble and operate it according to demand listed in this “service manual” strictly. During run state, temperature, humidity, vibration and aging parts will affect it, which may cause failure of the inverter. To void this, it is recommended to perform routine inspections and maintenance.

    Maintenance a. If did not use the inverter according to service manual strictly or did not use it under ambient demanded in service manual, which cause failure. b. Failure caused by applying the inverter to non-normal function; c. Failure caused by self-repair, refit which is not already allowed; d.

    Modbus communication protocol Appendix A Modbus Communication Protocol A.1 Summary We provide general RS485 communication interface in our inverters for the user. Through this communication interface upper device (such as HMI, PC, PLC controller and etc.) can perform centralized monitor to the inverter (such as to set inverter parameter, control run of inverter, read work state of the inverter).
