Connection terminal assignment
- Remove the screws and take off the
converter cover.
Type key Assignment
L1, L2, L3 Mains connection voltage
PE Earth terminal
IN1 Sensor input
IN2 External setpoint input
GND (x2) Ground terminals
+24 V Continuous power supply for sensor
Ext. Off ON/OFF control input
"DEACTIVATION priority"
for a potential-free external switch
SBM "Available transfer" relay
SSM "Failures transfer" relay
PLR Connection terminals of the PLR
communication interface
LON Connection terminals of the LON
communication interface
NOTICE: Terminals IN1, IN2, GND and Ext. Off meet
the requirements for "safe isolation" (in acc. with
EN 61800-5-1) at the mains terminals as well as at
SBM and SSM terminals (and vice versa).

x1
Signal nature: voltage (0-10 V, 2-10 V)
Input resistor: Ri ≥ 10 kΩ
Signal nature: current (0-20 mA, 4-20 mA)
Input resistor: R = 500 Ω

Can be configured in the "Service" menu <5.3.0.0>
Signal nature: voltage (0-10 V, 2-10 V)
Input resistor: Ri ≥ 10 kΩ
Signal nature: current (0-20 mA, 4-20 mA)
Input resistor: Rb = 500 Ω
Can be configured in the "Service" menu <5.4.0.0>
For each IN1 and IN2 input
Max. current: 60 mA.
The power supply is protected from short-circuits.
The potential-free external switch is used to activate
and deactivate the pump.
On installations with high numbers of starts
(> 20 per day), activation and deactivations should
be performed 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 malfunction occurs
or if the main power supply is disconnected (pump
switches off).
Pump availability, even temporarily, can thus be signalled to
the switchgear.
Can be configured in the "Service" menu <5.7.6.0>
Potential-free contact:
minimum: 12 V DC, 10 mA
maximum: 250 V AC, 1 A
If consecutive malfunctions of the same type are
detected (from 1 to 6 according to significance),
the pump switches off, and this relay is activated
(until manual intervention).
Potential-free contact:
minimum: 12 V DC, 10 mA
maximum: 250 V AC, 1 A
The optional IF module PLR can be inserted into the
multiple connector placed in the converter connector area.
The module is protected from polarity reversal.
The optional IF module LON can be inserted into the
multiple connector placed in the converter connector area.
The module is protected from polarity reversal.
