Installation notes

  • module address must be at detailed design phase with RCU circuit schedule, scene schedule planned together
  • DIN rail/low-voltage cabinet installation must reserved cooling space, terminals torque per factory specification
  • Wire per project drawing; signed projects use factory shipment drawings
  • after power-on with RCU commissioning: output actions, bus communication, scene linkage item-by-item acceptance
