CAUTION!
Provide a separate power supply for the external fan with
motors with external fans (identity code specification "R" or
"Z").
Connect the motor as per the wiring diagram for the controller, if it is con‐
trolled by an electronic control unit (such as direct current motors by a fre‐
quency converter).
Connect the motors in accordance with the enclosed wiring diagram or as
per the wiring diagram fixed to the inside of the housing.
CAUTION!
Only operate stroke length actuators / control drives when
the pump is running!
Otherwise they will become damaged.
WARNING!
Danger of electric shock
In event of a defect, there is a risk of electric shock when
conductive feed chemical are used.
–
For safety reasons we recommend connecting to a pro‐
tective low voltage, e.g. in accordance with EN 60335-1
(SELV ).
WARNING!
Risk of fire after a diaphragm rupture
The electric diaphragm rupture sensor must switch off the
pump immediately after a diaphragm rupture.
–
Connect the pump and the diaphragm rupture sensor to
a control so that the pump is stopped immediately in the
event of a diaphragm rupture.
CAUTION!
Danger resulting from unnoticed diaphragm rupture
If the pump has been ordered with an electric diaphragm rup‐
ture sensor, it must also be electrically installed.
–
Install the enclosed diaphragm rupture sensor electri‐
cally to a suitable monitoring device.
CAUTION!
Additional damage with a ruptured diaphragm
The diaphragm cannot be allowed to rupture fully if damage
can be caused by hydraulic oil mixing with the feed chemical.
–
The diaphragm rupture sensor must switch off the pump
immediately.
Only restart the pump once the diaphragm has been
replaced.
