Connection to Modbus devices with non-isolated RS485 interfaces 

Fig. 20. Connection (L > 3 m) of RS485 interfaces 1, 2, or 3 (RS485 interface 1 shown) to a Modbus

NOTES:

—

N = max. 30 unit loads. Always power the CPO-PC400-W/CPO-PC400-UW and connected Modbus modules 

with separate transformers. Termination resistors must be inserted directly into the terminals of the individual 

Modbus modules.

—

Signal ground (signal reference) connection is recommended. For more information, see “General Information 

on the RS485 Standard” section on page 7.

—

For communication cable lengths, transmission speeds, and termination, see “General Information on the 

RS485 Standard” section on page 7. For fusing, see “Fusing” section on page 11.
