This presents the risk of severe cases of electric shock!
Always cut off power supply to the equipment before mounting, removing or connecting
the terminal strips , !

The control unit NRS 1-40.1 features four limiting functions for monitoring water level and temperature.
The level electrodes NRG 1x-40, NRG 1x-41.1 and the temperature transmitter TRV 5-40 can be connected
to the control unit.
For the operation in question the required number of limiting functions of the control unit NRS 1-40.1 has
to be ascertained.
With lower terminal strip unplugged:
Set the baud rate via code switch Fig.4 (S1 to S6) as specified in the table by using a thin blade screw-
driver.

Since the components are easier to access before the the equipment is mounted you should change the
configuration before carrying out the installation.
