Connection terminal allocation
• Loosen the screws and remove the converter
cover.
Designation Allocation
L1, L2, L3 Mains connection voltage
PE Earth connection
IN1 Sensor input
(DDS-terminal 9)
IN2 External setpoint input
(10V/20mA-terminal 7)
GND (x2) Ground connections
+ 24 V DC voltage for sensor
Ext. off Control input ON/OFF
« Overriding OFF »
For external potential-free switch
SBM « Available transfer » relay
SSM « Failure transfer » relay
The terminals IN1, IN2, GND and Ext. Off meet
the requirement for « safe isolation » (in acc.
with EN61800-5-1) to the mains terminals, as
well as to the SBM and SSM terminals (and vice
versa).

Notes
Three-phase current 3 ~ IEC38
Type of signal: Voltage (0 - 10 V, 2 - 10 V)
Input resistance: Ri ≥ 10 kΩ
Type of signal: currrent (0 - 20 mA, 4 - 20 mA)
Input resistance: R = 500 Ω
b
Can be configured in the « Service » menu <5.3.0.0>
Type of signal: Voltage (0 - 10 V, 2 - 10 V)
Input resistance: Ri ≥ 10 kΩ
Type of signal: currrent (0 - 20 mA, 4 - 20 mA)
Input resistance: R = 500 Ω
b
Can be configured in the « Service » menu <5.4.0.0>
For both inputs IN1 and IN2.
Load max. : 60 mA
The voltage is short-circuit proof.
The pump can be switched on/off via the external
potential-free contact.
In systems with a high switching frequency
(> 20 switch-ons/offs/day), switching on/off is to be
done via « ext. off ».
In normal operating, the relay is activated when the
pump runs or is in a position to run.
When a first defect appears or by main supply cutoff
(the pump stops), the relay is deactiveted.
Information is given to the control box, regarding the
availability of the pump, even temporarily.
Can be configured in the « Service » menu <5.7.6.0>
Contact load:
minimum: 12 V DC, 10 mA
maximum: 250 V AC, 1 A
After a series of detection (from 1 to 6 according to
significance) of the same type of defect, the pump
stops and this relay is activated (up to manual action).
Contact load:
minimum: 12 V DC, 10 mA
maximum: 250 V AC, 1 A
