2)
Matching the input voltage to the voltage requirements of the AC drive;
3)
The cable diameter and voltage resistance of the input and output shall meet the requirements;
4)
High voltage switches on the power supply side should have effective lightning protection
measures.
3.3.5 Wiring of the Control Circuit
The ACH200 series high voltage AC drive user I/O interface board provides 8 switch inputs,
8 switch outputs, 4 analogue inputs and 5 analogue outputs (switch and analogue can be extended
according to user requirements), while optional relay outputs are supported.
