Connection terminal assignment
- Remove the screws and take off the
converter cover.
NOTICE: Terminals IN1, IN2, GND and Ext. Off meet
the requirements for “safe isolation” (in acc. with
EN 61800­5­1) at the mains terminals as well as at
SBM and SSM terminals (and vice versa).
Type key Assignment Remarks
L1, L2, L3 Mains connection voltage Three­phase current 3 ~ IEC38
PE Earth terminal
IN1 Sensor input Signal nature: voltage (0­10 V, 2­10 V)
Input resistor: Ri ≥ 10 kΩ
Signal nature: current (0­20 mA, 4­20 mA)
Input resistor: R
b
= 500 Ω
Can be configured in the “Service” menu <5.3.0.0>
IN2 External setpoint input Signal nature: voltage (0­10 V, 2­10 V)
Input resistor: Ri ≥ 10 kΩ
Signal nature: current (0­20 mA, 4­20 mA)
Input resistor: Rb = 500 Ω
Can be configured in the “Service” menu <5.4.0.0>
GND (x2) Ground terminals For each IN1 and IN2 input
+24 V Continuous power supply for sensor Max. current: 60 mA.
The power supply is protected from short­circuits.
Ext. Off ON/OFF control input
“DEACTIVATION priority”
for a potential­free external switch
The potential­free 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”.
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 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>
Potential­free contact:
minimum: 12 V DC, 10 mA
maximum: 250 V AC, 1 A
SSM “Failures transfer” relay 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).
Potential­free contact:
minimum: 12 V DC, 10 mA
maximum: 250 V AC, 1 A
PLR Connection terminals of the PLR
communication interface
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.
LON Connection terminals of the LON
communication interface
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.
