1. Connect and install the equipment in strict accordance with the requirements of the inverter instruction manual. During installation, carefully check whether the wiring meets the requirements, whether the components and terminals are loosened during transportation, whether the insulation is properly insulated, and whether the grounding of the system meets the requirements.

2. Operate in strict accordance with the inverter instruction manual. Before starting, we should pay attention to whether the input voltage is normal. During operation, we should pay attention to whether the order of switching on and off the machine is correct, and whether the indicator light and the table head are normal.

3.  inverter generally has short circuit, over current, over voltage, over temperature protection, so in the occurrence of these phenomena, without manual shutdown, automatic protection will start immediately, generally in the factory has been set, no need to adjust.

4. There is high pressure in the inverter cabinet, and the operator is generally not allowed to open the cabinet door, which should be locked in peacetime.

5.  When the indoor temperature exceeds 30℃, heat dissipation and cooling measures should be taken to prevent equipment failure.
