3-Conductor Track System - LDT DigitalBooster DB-4 Assembly Instruction Manual

DigitalBooster DB-4 – Manual
The digital current of the DigitalBooster DB-4 is available at the clamp KL1 next to
the two light emitting diodes.
The DB-4 supplies digital current to the own track section via this clamp. This
section has to be electrical separated from the adjoining track sections because
those receive their supply from the digital command station with integrated
booster or from further booster.

4.1. 3-Conductor Track System:

If the manufacturer of your digital command station permits a common layout ground
("brown") the center conductor of the 3-conductor track has to be isolated at the
cross over joints from one to the next booster electrical circuit. The isolated center
conductor gets the supply from the connection "red" of the clamp KL1 of the
DigitalBooster DB-4.
