Precautions are as follows:
1) Terminal
◎
refers to Main circuit terminal, terminal
○
refers to control circuit terminal;
2) B which is followed the product model represents standard models built-in brake unit;
3) Braking resistor’s selection is based on the user demand. refer to Table 2-4;
4) Signal lines and power line must be separated alignments, if you want to control cables and power
cable cross, let them cross by 90 degree angle. It is best to choose shielded twisted-pair cabling for
analogue signal, the selection of power cable is shield three-core cable(The specification should
enlarge a class as much as the ordinary electric cables), or follow the inverter user manual.
