Wiring in lift - SmartRelay 3 system

Lift cabs are connected to the external system via trailing cables. The number of available lines is limited by the trailing cable type. You can save on free lines if you decide on a configuration with few lines.

IMPORTANT

Malfunctions due to voltage drop

The physically induced voltage drop in the trailing cable may cause low voltages in power supplies which come from outside the cab.

  1. Take the cable length into account.
  2. Switch to a version with power supply in the cab if necessary (see Common earth with power supply and Common earth with SREL3 components).
  3. Make the cable gauge larger by merging lines in the trailing cable.
