• This GP unit’s serial port is not isolated. When the host (PLC) unit is
also not isolated, and to reduce the risk of damaging the RS-422 circuit,
be sure to connect the #7 SG (Signal Ground) terminal.
• Pin #14 (VCC) DC 5V Output is not protected. To prevent damage or unit
malfunction, use only the designated level of current.
• Inside the GP2500/2600 unit, the SG (Signal Ground) and FG (Frame
Ground) terminals are connected to each other.
• When connecting an external device to the GP with the SG terminal,
ensure that no short-circuit loop is created when you setup the system.
Use rough metric type M2.6 x 0.45p threads to hold the cable’s set
(fastening) screws in place.
„
