WRM-4
4.5. Connecting the power supply
Connect the voltage supply according to the list "pin assignment" and the connection
diagrams. Observe the polarity when connecting to a d.c. power pack.
When connecting the WRM-4 to an a.c. transformer, first of all the polarity is of no
importance. However, when making the connections between the different components you
have be careful to assign earth and voltage consistently.
4.6. Embedding in a digitally controlled layout
When you want to use the WRM-4 in combination with a turnout decoder in a digital layout,
make the connections according to the diagram.
Attention:
!
Do not connect the WRM-4 to the voltage supply for the digital system. The occurent
leakage current would damage the detector irreparably! Use a separate transformer as
voltage supply for the WRM-4 (and in case further turnout indicators).
