Rules
- No contact of the rails (ergo, safe electrical disconnection).
- Connection cables for the digital voltage (interface cable):
- double flexible wire,
- cross section at least 0.75 mm²,
- for the right rail (looking from the middle of the module to one end) a 4 mm banana plug, favourably with additional hole at the end,
- for the left rail a 4 mm banana jack,
- can be extract to 0.3 m over the edge of the module's end,
- at multiple tracks separately for each track (because of vehicle detectors).
- For safety reasons: No connection for AC, just not for low voltage.
Best Practices and Illustrations
- Connection cables for the digital voltage (interface cable):
The connection method, introduced here, is the record holder, concerning fast assembling and low error rate. For the first time it should have been described from the section H0e.
In fact, the interface cables and the parallel cable (see above) may be the same unit. It is better, to install it as three pieces, and to connect them with luster terminals at the inside of the profile. They work as protective predetermined breaking point, and support the replacement of defective "pigtails".
Preferable cable color are brown or red/black; white and black are reserved for other usage. The plugs should be red, but in no case blue (see below "feeder cable").
An additional hole at the plugs makes it easier to connect a booster or an extension cable (more comfortable if in the interface cable, but sufficient in the additional cables). Plugs with holes at the end are more expensive than plugs with transversal, put are a better protection against short-circuits.
Needless long "pigtails" increase the cable chaos. Who places connection jacks deep inside the module, also has to provide the necessary cables!- No connection for AC:
Such connections lead to – worse of mostly unknowingly – parallel circuit of the secondary winding of the transformers. If one of the transformers is unplugged from the main power, the full main power voltage applies at it's blank contacts, even sometimes more. Therefore, power additional consumer with DC as possible(see above)!
- Feeder cable:
This is a two-core passing cable without electrical connection to the module, the same connection technique as for the connection cable (brown or red/black cable, blue plugs). It makes a route module, designed for digital operation, usable for analog operation ("W-Circuit").
