NOTE: Terminals IN1,IN2, GND and Ext. Off meet the
requirements for „safe isolation“ (in acc. with EN61800-5-
1) at the mains terminals as well as at SBM and SSM termi-
nals (and vice versa).

- Remove the screws and take off the converter
cover.
Designation Assignment Notes
L1, L2, L3 Mains connection voltage Three-phase current 3 ~ IEC38
PE Earth connections
IN1 Input sensor Type of signal: Voltage (0 – 10 V, 2 – 10 V)
Input resistance: Ri ≥ 10 kΩ
Signal type: current (0 – 20 mA, 4 – 20 mA)
Input resistance: R
B
= 500 Ω
Can be configured in the „Service“ menu <5.3.0.0>
IN2 External input setpoint Type of signal: Voltage (0 – 10 V, 2 – 10 V)
Input resistance: Ri ≥ 10 kΩ
Signal type: current (0 – 20 mA, 4 – 20 mA)
Input resistance: R
B
= 500 Ω
Can be configured in the „Service“ menu <5.4.0.0>
GND (x2) Earth connections For both input IN1 and IN2
+ 24 V DC voltage for sensor Max. load: 60 mA
The terminal is short-circuit-proof.
Aux Control input (Auxiliary)
„Overriding Off“
for external potential-free switch The pump can be switched on/off using the external
potential-free contact.
This input is provided for auxiliary functions,
e.g. dry-running sensor, etc.
Ext. off Control input (ON/OFF)
„Overriding Off“
for external potential-free switch The pump can be switched on/off using the external
potential-free contact.
In systems with a high cycling frequency (> 20 on/off
switching cycles per day), on/off-cycling is to be per-
formed via „Ext. off“.
SBM „Available transfer“ relay In normal operation, the relay is activated when the pump
is running or in standby.
The relay is deactivated if an initial defect occurs or if the
main power supply is disconnected (pump stops).
Pump availability is signalled to the control box.
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
SSM „Failures transfer“ relay If consecutive defects of the same type are detected
(from 1 to 6 according to significance), the pump stops
and this relay is activated (until manual intervention).
Contact load:
Minimum 12 V DC, 10 mA
Maximum: 250 V AC, 1 A
PLR Connection terminals at
PLR The optional IF-module PLR must be pushed into the
multiplug in the connection area of the converter.
The connection is protected against reversed polarity.
LON Connection terminals at
LON The optional IF-module LON must be pushed into the
multiplug in the connection area of the converter.
The connection is protected against reversed polarity.
