Wilo -Control SC-Fire Electric A2P Installation And Operating Instructions Manual page 42

• The power supply configuration, current type and the mains connection voltage must be in accordance
with the indications given on the rating plate of the device.
NOTE:
• Fuse on mains side in accordance with the information in the wiring diagram.
• Feed the ends of the mains cable through the threaded cable connections and cable inputs and wire
them according to the markings on the terminal strips.
• Earth the pump/system in accordance with the regulations.
NOTE:
In accordance with the standard EN/IEC 61000-3-11 (see the following table), the switchgear and
a pump of a performance of ... kW (column 1) are planned to be used within a power supply
network of an impedance system of Z
for a maximum number of ... connections (column 3).
If the mains impedance and the number of connections per hour are higher than the values shown
in the table, the switchgear related to the pump can, in the presence of unfavourable network
conditions, lead to temporary decreases in voltage as well as disruptive variations in voltage
("flickers").
It may require the implementation of measures before the switchgear and the pump can function in
a compliant way regarding this connection. Contact the local electrical energy supply company
and the manufacturer to obtain the necessary information.
