Modbus Wiring Diagrams

The Modbus wiring for the NMC in a Gutor system is done with a 4-wire configuration.

IMPORTANT: Always follow local wiring codes.
NOTE: It is recommended to use 150 Ohm resistors at each end of the Modbus bus cable if the cable is over 300 m (1000 feet) using 19200 as baud rate or over 600 m (2000 feet) using 9600 as baud rate.
