Install the Column Terminator onto the DIN rail

The Column Terminator terminates the redundant bus. It installs after the last CHARM Baseplate on the DIN rail.

Figure: Installing the Column Terminator


  1. Locate the last CHARM Baseplate or CHARM I/O Gateway Carrier on the DIN rail. The last CHARM baseplate typically has Address Plug 8.
  2. Ensure that the lock on the Column Terminator is in the locked position.
    Insert a screw driver into the lock and turn it counter-clockwise to engage the lock.
  3. Align the connectors on the Column Terminator with the connectors on the last baseplate or Distributed CHARMs I/O Gateway Carrier, and snap the terminator onto the DIN rail.

After installing the Column Terminator, you can install a DIN Rail Stop and then wire your field devices to the terminal blocks on the baseplates. Refer to the specifications for the CHARM Terminal Block and CHARM Injected Power Terminal Block in the DeltaV S-series and CHARMs Hardware Reference manual for information on the terminal block connectors. After wiring your devices, perform all standard field wiring checkout procedures.
