Precautions for PC connection to SEL unit
grounded at positive terminal of 24V DC power supply
If the SEL unit is grounded at the positive terminal of the 24V DC power supply, a PC
cannot be connected to the USB connector (mini-B) of the SEL unit.
If connected directly, short-circuiting of the power will occur as shown in the diagram below,
causing malfunction of the PC.
