Connection terminal allocation
• Loosen the screws and remove the converter
cover.
NOTE: 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).
DANGER! Danger of death!
Contact voltage hazardous due to the discharge
of the converter capacitors.
• Before any intervention on the converter, wait for 5
minutes after disconnecting of the supply voltage.
• Check whether all electrical connections and contacts
are voltage-free.
• Check the righ allocation of the connection terminals.
• Check the right earth connection of the pump and
installation.

IN1 Sensor input 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
B = 500 Ω
Can be configured in the « Service » menu <5.3.0.0>
IN2 External setpoint input 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
B = 500 Ω
Can be configured in the « Service » menu <5.4.0.0>
GND (x2) Ground connections For both inputs IN1 and IN2
+ 24 V DC voltage for sensor Load max. : 60 mA
The voltage is short-circuit proof
Ext. off Control input (ON/OFF)
« Overriding Off »
for external potential-free switch
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 ».
SBM « Available transfer » relay 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
SSM « Failures transfer » relay 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
PLR Connection terminals of the interface
PLR
The optional IF-Module PLR is to be pushed into the
multiplug in the connection area of the converter.
The connection is twist-proof.
LON Connection terminals of the interface
LON
The optional IF-Module LON is to be pushed into the
multiplug in the connection area of the converter.
The connection is twist-proof (Fig. 11).
