Network Cable Connection

Follow the instructions below to connect the bypass to a MEMOBUS/Modbus network.
1.
With the power shut off, connect the communications cable to the bypass controller board A2 and the master. Use
terminal TB3 for MEMOBUS/Modbus.
Note: Separate the communications cables from the main circuit cables and other wiring and power cables. Use shielded cables for
the communications cables, and properly shielded clamps to prevent problems caused by electrical interference.
2.
Check or set the termination resistor selection at all slaves. Use the description in
309 for slaves that are P1000 Bypasses.
3.
Switch the power on.
4.
Set the parameters needed for serial communications (Z3-01 through Z3-07) using the digital operator.
5.
Shut the power off and wait until the display on the digital operator goes out completely.
6.
Turn the power back on.
7.
The bypass is now ready to begin communicating with the master.
