Assembly / Commissioning
To eliminate the risk of interference via the motor supply
cable, a shielded cable must be used for this.
A thermostatic contact must also be connected to protect
the motor against excessive overheating at low speeds. If
no thermostatic contact is connected, the motor guaran-
tee will be invalidated.
Klingenburg frequency converters FC-KB 0.55 to 2.2 op-
erate with an output voltage of 3 x 230 V. For this purpose,
the motor in the pump station must be delta-connected.
Delta-connection
Klingenburg frequency converters FC-KB 4.0 and 5.5 op-
erate with an output voltage of 3 x 400 V. For this purpose,
the motor in the pump station must be delta-connected
(Motor 400/690 Volt).
Star-connection
The CERTO FU allows the processing of the following
control signals
0 - 10 V
4 - 20 mA
The control signals should be connected to terminals 8
and 9. Terminal 9 is reference potential (mass).

The CERTO controller lets you connect a special humidity
sensor (available as an accessory) directly to the device. It
is able to ensure the constancy of an adjustable humidity
value via the programming.
The humidity sensor is connected to the control unit as
follows:

Accordingly, the individual components should not be ex-
changed for other parts! In this case, please always con-
sult with our head office.
Should you have any enquiries concerning the device or
its components, please always quote the type and num-
ber of the device.
