10 Installation and Operating Instructions
ABS submersible wastewater pump AS
ATTENTION It is important to us the correct capacitors with single phase pumps, use of incorrect
capacitors will lead to motor burn-out

When carrying out the direction of rotation check as well as when starting the unit pay attention to the
START REACTION
. This can be very powerful
ATTENTION
The direction of rotation is correct
if the imeller/propeller rotates in a
clockwise manner when viewing
down from the top of the placed
unit
1020-00
ATTENTION
The start reaction is
anti clockwise
Figure 11 Rotor rotation
NOTE If a number of pumps are connected to a single control panel then each unit must be
individually checked.
ATTENTION The mains supply to the control panel should have a clockwise rotation. If the leads
are connected in accordance with the circuit diagram and lead designations, the
direction of rotation will be correct.
4.3.3 Changing direction of rotation

If the direction of rotation is incorrect then this is altered by changing over two phases of the power supply cable
in the control panel. The direction of rotation should then be rechecked
NOTE The direction of rotation measuring device monitors the direction of rotation of the
mains supply or that of an emergency generator
