NOTE
The terminals In1, In2, aux, GND, ext. Off and MP meet the require-
ment for "safe isolation" (in acc. with EN 61800-5-1) to the mains
terminals, as well as to the SBM and SSM terminals (and vice versa).
• Establish connections observing the terminal allocation.
• Earth the pump/installation in accordance with regulations.
Notes
Three-phase current 3~400 V AC, 50 Hz, IEC 38.
Type of signal: Voltage (0-10 V, 2-10 V)
≥ 10 k9
Input resistance: R

Type of signal: Current (0-20 mA, 4-20 mA)
= 500 9
Input resistance: R

Can be configured in the service menu <5.3.0.0>
Connected in the factory via the M12 threaded cable connec-
tion (Fig. 18), via (1), (2), (3) according to the sensor cable
designations (1,2,3)
The In2 can be used as input for the setpoint remote adjust-
ment for all operating modes.

Can be configured in the service menu <5.4.0.0>
For both input In1 and In2
DC voltage for an ext. consumer/sensor. Load max. 60 mA.
The voltage is short-circuit proof.
Can be configured in the service menu <5.1.3.2>
Interface for dual pump function
The pump can be switched on/off via the external potential-
free contact.
In systems with a high switching frequency (> 20 times
switching on and off per day), switching on/off is to be done
via "ext. off".
Can be configured in the service menu <5.1.7.0>
Contact load: 24 V DC/10 mA
Potential-free individual run signal/collective run signal
(changeover contact), operation readiness signal is available
at the SBM terminals (menus <5.1.6.0>, <5.7.6.0>).
Minimum permissible: 12 V DC, 10 mA,
Maximum permissible: 250 V AC, 1 A.
tact) is available at the SSM terminals (menu <5.1.5.0>).
Minimum permissible: 12 V DC, 10 mA,
Maximum permissible: 250 V AC, 1 A.
The optional IF-Module PLR/IF-Module LON is pushed into
the multiplug in the terminal box.
The connection is twist-proof.
