1. Try to avoid working the variable frequency power supply device for a long time under severe detuning conditions.

2. Regularly check the internal wiring of the inverter cabinet device and the tightening of screws at each contact to prevent loosening.

3. The equipment should be stored in a dry, clean, and moisture resistant place. When not in use, cover with a dust cover to prevent dust from entering the cabinet through the air duct.

4.During transportation, the frequency conversion cabinet should be secured with specialized straps to prevent loosening and slipping.

5.When the frequency conversion cabinet malfunctions, please contact Wuhan Guodian Huamei Electrical Equipment Co., Ltd. in a timely manner.

6. The display screen of the control box should not be exposed to sunlight, and the control box should have anti vibration measures during transportation.

7. The connectors in the equipment are prone to damage. Be careful when using to prevent blockage by dirt.

8. When using optical cables, be careful to prevent them from bending, twisting, or squeezing; And keep them away from sources of fire. When using the plug, align it with the positioning slot and do not apply force. After use, please place the optical cable in a suitable location to prevent moisture.

Equipment transportation and lifting

Taking the transportation equipment for partial discharge testing of transformers as an example. It is recommended to fix the equipment during transportation and use. This method does not require lifting the equipment from the vehicle to the ground during on-site testing, improving work efficiency. During transportation, please firmly fix the equipment on the vehicle (when fixing the variable frequency power supply, the four lifting rings on the top must be tightened, otherwise it will cause deformation of the variable frequency cabinet), to prevent sliding and tilting.

The lifting of the variable frequency power cabinet must be carried out simultaneously at the four circular holes on the top, and it is strictly prohibited to lift it in other parts. Lifting equipment is required to have relevant load-bearing capacity, and attention should be paid to relevant precautions during lifting.
