Before operating the MS300 series products, please read and pay attention to the relevant safety information to ensure your own safety and product safety.
When operating the wiring and installing the inverter, it is necessary to confirm that the power supply is closed.
After the communication power supply is blocked, the POWER indicator of the inverter (located behind the digital operator) is not calmed down, indicating that there is still high voltage inside the inverter, do not touch the internal circuits and components.
The circuit components on the internal circuit board of the inverter are susceptible to damage by static electricity, so do not touch the circuit board with your hands before the anti-static measures are taken.
Do not modify the internal parts or wiring of the inverter by yourself.
It is necessary that the drive terminals are properly grounded in accordance with local regulations.
In the case of inverter and accessories, it should be kept away from fire sources, heating elements and flammable materials.
Do not input the AC power supply to the output terminals U/T1, V/T2, and W/T3 of the inverter.
The additional voltage of the power supply system installed by the inverter is as follows, please do not exceed this applicable scale:
The scale of change of 1.115V series models is 85V - 132V.
2. The scale of change of 230V series models is 170V - 264V.
3. The scale of change of 460V series models is 323V-528V.
The scale of change of 4.575V series models is 425V-660V.
Please refer to the following table for short-circuit current capacity:
Series model (power) short-circuit current capacity
115V 5kA
230V 5kA
460V 5kA
575V 5kA
Only qualified motor professionals are required to install, wiring and repair the inverter.
Even if the three-phase communication motor is aborted, the main circuit terminals of the inverter may still carry dangerous high voltages.
If an electrolytic capacitor is left unpowered for a long time, its function will be reduced. Therefore, it is necessary to energize the inverter for about 3-4 hours every 2 years (note) to restore the function of the electrolytic capacitor inside the inverter.
Note: When the inverter is powered, it is necessary to use an adjustable AC power supply (such as AC autotransformer) to power on at an additional voltage of 70-80% for 30 minutes (do not run), and then power on with an additional voltage for 1 hour (do not run), so that the function of the electrolytic capacitor inside the inverter can be restored, and then start to run the inverter, and the power cannot be directly transmitted to the additional voltage.
Precautions for insect removal treatment of outer box packaging (including wooden boxes, wooden strips, etc.) during transportation and installation:
1. If the wooden packaging materials used for packaging need to be dewormed, the use of fumigation methods should be prohibited, and if the machine is damaged as a result, it will not be included in the warranty scale.
2. Please choose other methods, such as wood box heat treatment or other non-fumigation methods for pest removal operations.
3. When using the high temperature method of heat treatment of wooden box: the packaging material can be kept in an environment with a temperature of more than 56 °C for more than 30 minutes.
Please connect the three-phase 3-wire Y-connected power system or the three-phase 4-wire Y-connected power system to meet UL standards.
If the leakage current of the inverter exceeds the communication of 3.5mA or 10mA DC on the protective grounding conductor, the small specifications of the selected protective grounding conductor shall conform to the local national regulations or be grounded according to IEC61800-5-1.
