CHARM Column Extenders and cable

Installation notes

• The CHARM Column Extenders are used to extend the power and communications busses when CHARM Baseplates in a 96 CHARM system are installed on multiple DIN rails.
• The bottom column extender can be connected to a CHARMs Smart Logic Solver (CSLS) Carrier or to a baseplate depending upon the physical location of the carrier and the baseplate. For example, if the CSLS carrier only is installed on a DIN rail and the baseplates are installed on another DIN rail, the bottom column extender would be connected to the CSLS carrier and either another bottom extender or top extender could be connected to a baseplate on the other DIN rail. Refer to the second image in this topic.
• The top column extender can be connected to baseplates only.
• To connect the cables between the extenders, connect primary to primary and secondary to secondary.
• Three cable lengths are available for use with the extenders:
  • 0.5 meters (1.64 feet)
  • 1.0 meters (3.28 feet)
  • 2.0 meters (6.56 feet)
• A maximum of four extender pairs can be used and only one extender pair can exceed 0.5 meters (1.64 feet).
