Direction of rotation check (for
three-phase current motors only)
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!
