The connection cable is equipped with a CEE plug. The connection to the mains is es-
tablished by inserting the plug into a socket. The plug is not overflow-proof. Install the
socket so that it is overflow-proof! Observe the information on the protection class
(IP) of the plug.
DANGER! If the pump is to be connected directly to the switchgear, arrange for the
electrical connection to be carried out by a qualified electrician!
Motor protection must be set depending on the selected activation type.
At full load, set the motor protection switch to the rated current (see rating plate). At
partial load, it is recommended to set the motor protection switch 5 % above the cur-
rent measured at the duty point.
It is not possible to connect the device to a soft starter!
Operation on the frequency converter is not permitted.

served for it.
▪ Making the installation and operating instructions available in the language of the per-
sonnel.
▪ Making sure that the installation and operating instructions are read and understood by
all personnel.
▪ All safety devices and emergency cut-outs on the system-side must be active and
checked to ensure that they work properly.
▪ The pump is suitable for use under the specified operating conditions.
The pump has been checked and adjusted to the correct direction of rotation for a
clockwise rotating field at the factory. Connection is made in accordance with the spe-
cifications in the "Electrical connection" chapter.
Checking the direction of rotation
A qualified electrician checks the rotating field at the mains connection with a rotating-
field testing device. To allow the correct direction of rotation, a clockwise rotating field
must be available at the mains connection. The pump is not approved for operation
with a counter-clockwise rotating field! CAUTION! If the direction of rotation is
checked with a test run, comply with the environmental and operating conditions!
