The electrical wiring must be performed ac-
cording to the wiring diagram shown inside
the terminal
box cover.
(Please see above sample
wiring diagrams)
:
Wiring diagram e.g.
There may be no foreign objects such as dirt, par-
ticles or humidity inside the terminal board.
– Mount terminal board cover to motor tight
against dust and humidity and close up all un-
used wiring ports.
ATTENTION
When Variable Frequency Drives are used in-
terfering signals might occur.
Non-sinus shaped supply voltage from a varia-
ble frequency drive might result in elevated
motor temperatures.

Start up / Shut down
6.1
Start up
ATTENTION
– After connection the electrical wires, close
the terminal box. Briefly start the motor
(max. 30 sec.).
– Check the rotation according to the arrow
on the top of the motor.
If the direction is incorrect change over two of the
power leads.
6.2
Shut down
WARNING
Electric shock!
All service work must be carried out by quali-
fied service personnel. Pump must be discon-
nected from the power source and all rotating
parts must stand still. Reassure that pump is
disconnected from power source and cannot
be switched on.
– Verify that there is no voltage at the termi-
nal board!
– Open terminal box and disconnect the power
leads.
– Empty out the pump.

Operation
WARNING
Risk of injury by uncontrolled start-up of the
pump or absence of emergency shutt of
switch!
– Unwanted pump start-up or missing shut off
switches can cause severe injury through
ejected parts from the pump discharge or
from cutting or pulling body parts into the
pump suction.
– Reassure that pump is disconnected from
power source and cannot be switched on.
– It is the responsibility of the machine opera-
tor to decide whether or not an additional
emergency switch must be installed.
Liquid level
According to the drawing 3, the maximum liquid
level must stay about 30 mm below the mounting
flange.
The pump begins to prime once the liquid level
(coolants) reaches the agitator.
The pump suction is at the bottom of the immersed
pump body.
The pump draws the fluid level down to the level of
the agitator.
The bottom of the agitator must be located 100 mm
above the tank bottom (see drawing 3) in order to
prevent unwanted objects, such as broken tools or
indexing plates from entering the pump suction.
This distance is critical and must be maintained at
all times.
