DANGER
Risk of fatal electrical shock!
Water on the upper part of the electronic module can enter the elec-
tronic module when it is opened.
• Before opening, remove water, e.g. on the display, by wiping it off
completely. Avoid water penetration in general!
DANGER
Potentially fatal injury due to electronic module not being in-
stalled!
A life-threatening voltage may be present at the motor contacts!
Normal operation of the pump is only permitted with the electronic
module installed.
• Never connect or operate the pump without the electronic module
mounted!
CAUTION
Material damage due to improper electrical connection!
An inadequate mains design can lead to system failures and
cable fires due to mains overload!
• When designing the mains supply with regard to the used cable cross-
sections and fuses, pay special attention to the fact that, in multi-
pump operation, it is possible that all pumps operate at the same time
for short periods.
CAUTION
Danger of material damage caused by improper electrical con-
nection!
• Ensure that the current type and voltage of the mains connection cor-
respond to the specifications on the pump rating plate.
Before the pump can be electrically connected, loosen the upper part of the electronic
module:
1.
Loosen the screws of the electronic module (Fig. I, Item 3) and remove the upper part
of the electronic module (Fig. I, Item 2).
2.
Establish electrical connection according to this section.
3.
Re-mount the upper part of the electronic module (Fig. I, Item 2) and tighten the four
screws (Fig. I, Item 3). Observe torques.
Threaded cable glands and threaded cable connections
There are six cable bushings to the terminal room on the electronic module. The cable for
the power supply of the electric fan on the electronic module is mounted at the factory.
The requirements for electromagnetic compatibility must be observed.
CAUTION
In order to ensure IP55, unoccupied threaded cable glands must remain
closed with the plugs provided by the manufacturer.
• When installing the threaded cable gland, make sure that a gasket is
installed below the threaded cable gland.
Threaded cable glands including gaskets for the cable bushings 2 ... 5 are enclosed with the
product as a kit.
