ENGLISH
vourable mains connections, the switchgear with the pump
may lead to temporary voltage drops and also to disturbing
voltage fluctuations, or flickering.
Therefore, measures may be necessary before the switchgear
with pump can be operated correctly on this connection. The
necessary information must be obtained from the electricity
supply company and the manufacturer.
A complete Table up to 30.0 kW nominal motor power can be
requested from SALMSON..

Sensors:
Following the Installation and operating instructions, connect
the sensor to the terminals correctly in accordance with the
wiring diagram.
Use shielded cable, place shield on one side in the switchbox.
Do not connect any interference voltage
ATTENTION!
to the terminals!
Analogue IN, remote setpoint adjustment/remote speed
adjustment:
A remote adjustment of the setpoint via the respective termi-
nal shown in the wiring diagram or of the speed in the "Control-
ler" operating mode can be undertaken by means of an
analogue signal (0/4...20 mA). Use shielded cable, place shield
on one side in the switchbox.
Do not connect any interference voltage
ATTENTION!
to the terminals!
Setpoint changeover:
A switching of setpoint 1 to setpoint 2 or 3 via the correspond-
ing terminals in accordance with the wiring diagram can be
forced by using a potential-free contact (normally open con-
tact).
