Adjusting

Rotation direction monitoring for three-phase motors:
To check the direction of rotation, remove the screw plug on
the longitudinal side of the motor. Switch on briefly to check
whether the direction of rotation of the pump matches the
arrow on the rating plate. If the direction of rotation is incorrect,
swap two electrical phases.
Speed
The speed is adjusted by means of the rotary knob on the
terminal box (fig. 8).
Note: If on a double pump both the individual pumps are in
operation at the same time, the selected speeds must be
identical for both pumps.
9 Maintenance
DANGER! Risk of fatal injury!
There is a risk of fatal injury from electric shock when work-
ing on electrical equipment.
• The pump should be electrically isolated and secured against
unauthorised switch-on for any maintenance or repair work.
• Any damage to the connection cable should only ever be
eradicated by a qualified electrician.
After successful maintenance and repair work, install and con-
nect the pump according to the "Installation and electrical con-
nection" chapter. Switch on the pump according to the
"Commissioning" chapter.
