6. Mounting the locomotive decoder
Caution:
Before mounting the decoder check if the maximum locomotive
motor´s current on-load is below the maximum permissible value. If it
is above the decoder is not suitable for mounting in this locomotive. It
would be damaged when put into operation or with decoders with
overload protection (LD-G-30, LD-G-33 and LD-G-34) switched off.
LD-G-decoders: Using decoders with interface connectors
Many recent locomotives with d.c. motor are equipped ex works with an
interface socket according to NEM 651, NEM 652 or NEM 658. The
interface enables you to connect the motor to the motor, the rail
current collectors, the lighting and – provided the special connector is
designed for it – additional accessories.
Using a decoder with a suitable connector saves separating the
connections and soldering works at the locomotive. When mounting
decoders with 6-pole interface connectors according to NEM 651 or 8-
pole interface connectors according to NEM 652, take care to put the
markings on the connector and on the socket on top of each other. The
12-pole PluX-connectors according to NEM 658 can be mounted in one
direction only.
Mounting decoders without interface connector
Open the locomotive housing. Locate the position for the decoder.
Disconnect the motor from the rail current collector or the change-over
switch from the motor and rails if you have a locomotive with electronic
change-over switch. The change-over switch is no longer necessary,
you can remove it.
Caution:
The interference suppression devices mounted to the motor or the
connecting wire must not be removed! Motor and interference
