Appendix A - System Communication Schematics

NOTE: The notice below pertains to all figures in this appendix.
NOTICE
HAZARD OF equipment damage, loss of operation
  • Maximize the distance between and segregate the 24 VDC and communications wiring from potentially noisy circuit breaker power cables.
  • If 24 VDC and communications wiring must cross power cables, cross as close to 90 degrees to the power cables as possible.
  • Limit parallel runs of control cable and power cables to the absolute minimum possible.
  • Flatten control cables and route along metallic structure when possible. Do not create loops with surplus cabling.
Failure to follow these instructions can result in equipment damage.
