Fig. 8d - Terminal arrangements
An enhanced version of terminal block may be present on the
transmitter.
See fig. 8d. The difference in respect to the one already
described in picture 8a is that there are three terminal points,
for connection to the power supply/signal and to an external
remote indicator.
Refer to Electrical connections scheme in fig. 8e and fig. 8f.
