NOTE:
The terminals IN1, IN2, AUX, GND, Ext. Off and MP meet the require-
ment for "safe isolation" (in acc. with EN61800-5-) to the mains ter-
minals, as well as to the SBM and SSM terminals (and vice versa).
NOTE:
The control is designed as a PELV (protective extra low voltage) cir-
cuit, meaning that the (internal) supply meets the requirements for
safe supply isolation; the GND is connected to PE.

Tab. 6: Differential pressure sensor cable connection
NOTE:
The electrical connection of the differential pressure sensor is to be
fed through the smallest threaded cable connection (M12) on the
electronic module.
For a double pump or Y-pipe installation, the differential pressure
sensor is to be connected to the master pump.
The measuring points of the differential pressure sensor of the master
pump must be on the suction and pressure side of the double-pump
system in the respective collector pipe.
• Establish connections observing the terminal allocation.
• Earth the pump/installation in accordance with the regulations.
The electronics module is operated using the following operating ele-
ments:
The red button (Fig. 32) can be turned to select menu elements and
used to change values. Pressing the red button activates a selected
menu element and confirms values.
The DIP switches (Fig. 14, Item 6/Fig. 33) are located under the hous-
ing cover.
• Switch 1 is for switching between the standard and service mode.
For additional information, see chapter 8.6.6 "Activating/deactivating
service mode" on page 98.
• Switch 2 allows activations or deactivation of the access disable feature.
For additional information, see chapter 8.6.7 "Activating/deactivating
access disable" on page 99.
• Switches 3 and 4 permit termination of the multi-pump communication.
For additional information, see chapter 8.6.8 "Activating/deactivating
termination" on page 99.
