Power supply via trailing cable
This connection option does not access existing lift electronics. This
means the lift electronics remain intact and a new inspection may be
avoided.
The components are powered via the trailing cable only. The required
power supply unit is at the other end of the trailing cable. Depending
on the length of the trailing cable, a possible voltage drop must be
taken into account to meet specifications (see Properties [} 121]).
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 [} 69] and Common earth with
SREL3 components [} 70]).
3. Make the cable gauge larger by merging lines in the trailing cable.
The SmartOutput module requires its own power supply. The reader
can also be connected to this power supply. Six free lines are
required in addition to the existing lines.
