Notes for installation and use of Marine packaging equipment inverter
Notes for installation and use of Marine packaging equipment inverter vacuum packaging machine inverter installation
(1) seafood packaging equipment inverter installation and use notes; Vacuum packaging machine inverter in the handling process should be carefully put, do not collision; Use the button hole on the side of the frequency converter for handling.
(2) Marine packaging equipment inverter installation and use notes; For the packaging machine inverter should choose a clean, dry, vibration free installation place, avoid installation in direct sunlight and high temperature place, allow the ambient temperature of 50℃.
(3) installation and use of Marine packaging equipment inverter note, vacuum packaging machine inverter installation, should make the nameplate on the cover plate in the direction visible to the operator; The panel should be installed in a place that is easy to operate.
(4) Marine packaging equipment inverter installation and use of notes; Inverter power terminal R, S, T wiring can not consider the phase sequence problem; The correct wiring of the output terminals U, V and W should be: it is not allowed to add power voltage to the U, y and W terminals.
(5) installation and use of Marine packaging equipment inverter note; When connecting the control terminals of the frequency converter, the shielded wire or laminated wire should be used and the remote wire should be used.
6 seafood packaging equipment inverter installation and use notes; As the frequency setting signal is a small current signal, when it is needed to access the contact, in order to prevent bad contact, it should choose double parallel contact.
7) notes for installation and use of frequency converter of seafood packaging equipment; When using reactors that vary the power factor, the associated AC AC reactors should not be accessed.
8) seafood packaging equipment inverter installation and use of notes; Special crimping terminal head should be used on the wire end of the main circuit to ensure good contact.
9) matters needing attention for installation and use of inverter of Marine packaging equipment; Terminal P and N are special terminals for brake and discharge resistance. They can only access the resistance, but not any other components
Attending to prevent the occurrence of electric shock accident, wiring can not touch the shell, but to ensure that the grounding terminal reliable grounding.
2. Matters needing attention for installation and use of frequency converter of seafood packaging equipment; Notes on the use of inverter of automatic vacuum packaging machine
(1) seafood packaging equipment inverter installation and use notes; The inverter of the full-automatic packaging machine should be connected to the power supply according to the regulations. The voltage should not be too high or too low.
(2) Marine packaging equipment inverter installation and use notes; It is not allowed to input voltage or other external power voltage on inverter output terminal of vacuum packaging machine, otherwise the inverter will be damaged. Especially when the inverter and power grid conversion operation, must take interlocking measures.
(3) seafood packaging equipment inverter installation and use notes; The P, N(O) terminals of the inverter are the special terminals of the brake equipment, and are not allowed to be used for other purposes of dc power supply.
(4) Marine packaging equipment inverter installation and use of notes; When using the air-controlled vacuum packing machine and the frequency converter of the box packing machine, the ambient temperature should be guaranteed to meet the requirements, especially for the frequency converter installed in the power distribution cabinet, the heat dissipation conditions of the power distribution cabinet should be fully considered.
(5) installation and use of Marine packaging equipment inverter note; Do not use circuit breaker or ac contactor directly to start and stop the motor (motor with inverter), use the operation stop button switch on the inverter to control the start and stop of the motor.
6 seafood packaging equipment inverter installation and use notes; When in use, the ac reactance coil used to change the power factor should be connected to the input end of the frequency converter.
7) notes for installation and use of frequency converter of seafood packaging equipment; The output end of the converter should not be connected with a capacitor that changes the power factor. It is also not allowed to access the surge absorption circuit, radio interference absorption circuit and so on.
8) seafood packaging equipment inverter installation and use of notes; When using the insulation resistance meter test, should be according to the requirements of the inverter manual.
9) matters needing attention for installation and use of inverter of Marine packaging equipment; Inverter does not allow overload operation. If the inverter thermal protection is cut off, it is not allowed to reset immediately to return to the operating state. The cause should be identified and the overload state removed before the operation can be resumed. If the load itself is too large, it should be considered to increase the capacity of the motor and inverter.
