Connection terminal assignment.
- Remove the screws and take off the converter
cover.
Designation Assignment
L1, L2, L3 Mains connection voltage
PE Earth connections
IN1 Input sensor
IN2 External input setpoint
GND (x2) Earth connections
+ 24 V DC voltage for sensor
Aux Control input (Auxiliary)
„Overriding Off"
for external potential-free switch
Ext. off Control input (ON/OFF)
„Overriding Off"
for external potential-free switch
SBM „Available transfer" relay
SSM „Failures transfer" relay
PLR Connection terminals at
PLR
LON Connection terminals at
LON
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).

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 = 500 Ω

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
Signal type: current (0 – 20 mA, 4 – 20 mA)
Input resistance: R = 500 Ω

Can be configured in the „Service" menu <5.4.0.0>
For both input IN1 and IN2
Max. load: 60 mA
The terminal is short-circuit-proof.
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.
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".
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
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
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.
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.
