Shield wire
Connect only one end of the shield to the FG terminal to avoid a ground loop. If both ends of the shield
wire are connected to the FG terminal, the circuit will be closed, resulting in a ground loop. This may
cause noise. Be sure to ground the FG terminal.
Recommended cable: OTSC-VB 2PX0.5SQ (made by Onamba Co., Ltd.) or equivalent (Use a twisted pair
cable.)
