Inverter selection principle - Schneider
1. Select the inverter according to the load characteristics.
2. When selecting the inverter, the actual motor current value should be used as the basis for the selection of the inverter, and the additional power of the motor can only be used as a reference. Secondly, the output content of the inverter should be fully considered.

Power wiring requirements for Schneider PLC
The power supply of the DPLC should be taken from the trunk line with a relatively stable voltage or the special line led by the bus of the substation to ensure the voltage quality of the PLC. If the voltage fluctuates too much, consider installing a voltage regulator or uninterruptible power supply (UPS). 2. The power cord is best to use twisted pair, and its cross-sectional area should not be less than 2 square millimeters.
