13.2 System impedance overview

In accordance with DIN EN / IEC 61000-3-11 (see
table below), the switchgear and pump with motor
power of ... kW (column 1) are provided for opera -
tion on a mains power supply with a system
impedance of Z
max
max. ... ohm (column 2) for a maximum number
of ... connections (column 3).
If the mains impedance and the number of con -
nections per hour are greater than the values
given in the table, the switchgear with the pump

may lead to temporary voltage drops and also to
disturbing voltage fluctuations (flickering) due to
the unfavourable mains conditions.
Therefore, measures may need to be taken before
the switchgear and the pump can be operated on
this connection as intended. The necessary infor -
mation must be obtained from the local energy
supply company and the manufacturer.
