19.3 Connection Diagram
RS-422/485 connection diagram 4)
*1
The signal name differs depending on the series name. Refer to the following table.
*2
Short-circuit between the following terminals of the energy measuring unit or electric multi-measuring instrument which will be a
terminal.
By the short circuit of the following terminals, a terminating resistor with 120 is connected.
*3
When placing the GOT to the terminal in the system configuration, set the terminating resistor to "110 ".
When placing the GOT to the position other than the terminal, set the terminating resistor of the GOT to "OPEN".
1.4.3 Terminating resistors of GOT
Set the 1pair/2pair signal selection switch to "1Pair" when using the connection conversion adapter.
