Use:
1. Connect and install the equipment in strict accordance with the requirements of the inverter operation and maintenance manual. During installation, carefully check whether the wire diameter meets the requirements; Whether all parts and terminals are loose during transportation; Whether the insulation place is well insulated; Whether the grounding of the system meets the requirements.
2, should be strictly in accordance with the provisions of the inverter operation and maintenance instructions. In particular, pay attention to whether the input voltage is normal before starting the machine; During operation, attention should be paid to whether the turn-on and turn-off sequence is correct, and whether the indications of each meter and indicator light are normal.
3. Inverters generally have automatic protection for open circuit, overcurrent, overvoltage, overheating and other items, so when these phenomena occur, there is no need for manual shutdown; The protection point of automatic protection is generally set at the factory, and no adjustment is needed.
4. When there is high voltage in the inverter cabinet, the operator is generally not allowed to open the cabinet door, which should be locked at ordinary times.
5. When the room temperature exceeds 30℃, heat dissipation and cooling measures should be taken to prevent equipment failure and prolong its service life.
Maintenance:
1. Regularly check whether the wiring of each part of the inverter is firm and loose, especially the fan, power module, input terminal, output terminal and grounding.
2. Once the alarm stops, it is not allowed to start the machine immediately. The machine should be started after finding out the reason and repairing it. The inspection should be carried out in strict accordance with the steps specified in the inverter maintenance manual.
3. Operators must be specially trained to judge the causes of common faults and eliminate them, such as skillfully replacing fuses, components and damaged circuit boards. Untrained personnel are not allowed to operate and use the equipment.
4. In case of an accident that cannot be easily ruled out or the cause of the accident is unclear, a detailed record of the accident should be made, and the inverter manufacturer should be informed in time to solve it.
