Chapter1 Safety information and precaution VFD500 high performance vector control frequency inverter user manual- 2 -Use stage Security Level Precautionsdamage to the drive! No part of the drive need to withstand voltage test, the product hasbeen made before the test. Otherwise it may cause accident!WARNING The driver must be covered before the cover can be powered,otherwise it may cause electric shock! All peripheral accessories must be wired according to the instructionsin this manual, and be properly wired in accordance with this manual.Otherwise it may cause accident!AfterPower-onDANGER Do not open the cover after power on, otherwise there is danger ofelectric shock! If the indicator light does not light after power on, the keyboard doesnot display the situation, immediately disconnect the power switch, donot touch any input and output terminals of the drive, otherwise there isthe risk of electric shock!WARNING If parameter identification is required, preclude the possibility of injurywhen rotating the motor! Do not arbitrarily change the drive manufacturer parameters, or it maycause damage to the device!DuringOperationDANGER Do not touch the cooling fan, radiator and discharge resistance to testthe temperature, otherwise it may cause burns! Non-professional technicians Do not detect the signal duringoperation, otherwise it may cause personal injury or equipmentdamage!WARNING Drive operation, should avoid something falling into the device,otherwise it will cause damage to the device! Do not use the contactor on-off method to control the start and stop thedrive, otherwise it will cause damage to the equipment!Maintenance DANGER Do not live on the equipment repair and maintenance, or there is a riskof electric shock! Turn off the input power for 10 minutes before performing maintenanceand repair on the drive, otherwise the residual charge on the capacitorwill cause harm to people! Do not carry out maintenance and repair on the drive withoutpersonnel who have been professionally trained, otherwise personalinjury or equipment damage will occur! All pluggable plug-ins must be unplugged in the case of power failure! The parameters must be set and checked after replacing the drive.WARNING Before performing maintenance work on the drive, make sure that themotor is disconnected from the drive to prevent the motor from feedingback power to the drive due to accidental rotation.1.2 Precaution Contactor usingIf the contactor is installed on the power input side of the inverter, do not make the contactor frequent on-offoperation. The interval between ON and OFF of the contactor should not be less than one hour. Frequentcharging and discharging will reduce the use of capacitors in the inverter life.If a contactor is installed between the inverter output terminals (U, V, W) and the motor, make sure that theinverter is turned on and off when there is no output. Otherwise, the inverter may be damaged. Lightning impulse protectionAlthough this series of inverters are equipped with lightning over-current protection device, there is a certaindegree of self-protection for inductive lightning, but for lightning frequent place, customers should also installlightning protection device in the front of the inverter. |
