Pin Function for Terminal Block:

External power supply is connected using the removable terminal block:
PWR : Power input (+18 ~ +32 VDC) and should be connected to the power supply (+)
GND : Ground and should be connected to the power supply (-)
F.G. : F.G. stands for Frame Ground (protective ground). It is optional. If you use this
pin, it can reduce EMI radiation; improve EMI performance and ESD protection.
