Motor data/Terminal diagram
n
Key motor data can be found on the nameplate and in the "Technical
data” chapter.
n
The terminal wiring diagram is located in the terminal box.
Motor data sheets, special motors, special motor
flanges, external fan, temperature monitoring
–
For further information on the motor with identity
code specification "S", refer to our website
www.prominent.com. Motor data sheets can be
requested for all other motors.
–
With motors other than those with identity code
specifications "S", "M" or "N": Pay special attention
to the operating instructions for the motors.
–
Special motors or special motor flanges are avail‐
able on request.
Provide a separate power supply for the external fan for 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 3-phase AC motors by 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.
Only operate stroke length actuators / control drives when the pump is
running. Otherwise they will be damaged.
Protective low voltage
n
In the event of a fault, there is a danger of electric shock if conductive
feed chemicals are present.
n
For safety reasons, we recommend connecting to protective low
voltage, e.g. in accordance with EN 60335-1 (SELV).
Danger resulting from unnoticed diaphragm rupture
n
If the pump has been ordered with an electric diaphragm rupture
sensor, it must also be electrically installed.
n
Electrically wire the enclosed diaphragm rupture sensor to a suitable
monitoring device.
a) Diaphragm rupture sensor with switch contact
The cable can be connected as required.
b) Namur sensor, inherently safe
Make sure that the monitoring/feed equipment installed by the customer is
capable of evaluating the current variations of the Namur sensor to indi‐
cate a diaphragm rupture.
The following applies in areas at risk from explosion:
n
Note the details of the type examination certificate PTB 00 ATEX 2048
X for the Namur sensor NJ1.5-8GM-N as well.
