Bus Coupler Wiring

Control power to TeSys island is connected through a single removable 2-pin spring terminal connector on the top of the bus coupler. The connector is for 24 V and 0 V connections. To wire the bus coupler:

1. Remove the spring terminal connector from the top of the bus coupler.

2. Referring to the table and figures below, make the power connections.

3. Insert the spring terminal connector back into the top of the bus coupler.

4. Connect the fieldbus cable(s) to the bus coupler. Connect the fieldbus Ethernet cables to the dual port Ethernet switch on the TPRBCEIP and TPRBCPFN bus couplers. Connect the PROFIBUS-DP cable to the DB-9 port on the TPRBCPFB bus coupler.

5. An RJ45 cable can be connected to the service port on the TPRBCEIP and TPRBCPFB bus couplers for communication with the digital tools.

   The service port on the TPRBCPFN bus coupler is intended for temporary use only during commissioning and troubleshooting.

1. The 24 Vdc power supply of the bus coupler must have an SELV rating. Install the power supply in the same panel or cabinet as the TeSys island .

2. One power supply (24 V, 3 A) should be used for only for oneTeSys island .
