The RF45X is normally mounted with the
shaft pointing upwards. It can, however,
also be mounted with the shaft pointing
downwards if that appears to be more
convenient.
NOTE!
In case of an “upside-down” installation,
the two plug-in straps on the component
side of the PCB have to be “turned” 90
° to
achieve reversed output signal. (To remove
the PCB from the housing, simply grip the
potentiometer and pull.
Shaft pointing up: Strap S2 to “N(ormal)”
Shaft pointing down: Strap S2 to
“I(nverted)”.
It should be noted that an “upside-down”
installation will make any adjustment and
service more convenient as the unit then
can be opened without removing the unit
from the mounting base.

fasten the link to the RF45X shaft preliminary. The transmission link can be
