If the data line is shorter than 500 m (547 yd) or if the data rate is slower than 9600 baud, the RS-485 terminator is not normally needed.
For marine applications, remove the grounding screw.
Enter the power and signal cables through the cable glands. For better protection against RF interference, ground the cable shield.

See Connections.
Connect the wires to the X2 removable screw terminal block. Tighten the output cable glands.
