Tab. 6 – System impedances and switching cycles
NOTE:
The maximum number of switching operations per hour specified in
the table for each power is determined by the pump motor and must
not be exceeded (adapt the parameterisation of the controller
accordingly; see follow-up times, for example).
• Provide fuse protection on mains side in accordance with the infor-
mation in the wiring diagram.
• Feed the ends of the mains cable through the threaded cable connec-
tions and cable inlets. Wire the cable ends according to the markings
on the terminal strips.
• The 4-wire cable (L1, L2, L3, PE) is to be provided on-site. The con-
nection is established at the main switch (Fig. 1a-e, item 1) or, for
systems of higher power, at the terminal strips in accordance with the
wiring diagram, and the PE is connected to the earth rail.
Pump mains connections
CAUTION! Risk of property damage!
Danger of damage due to incorrect handling.
• Observe the installation and operating instructions for the pumps.
Power connection
The pumps must be connected to the terminal strips in accordance
with the wiring diagram (SCe: directly to circuit breakers; see Fig. 1a,
item 4), and the protective earth conductor must be connected to the
earth rail. Use shielded motor cables.
Connecting cable shields to the EMC threaded cable connections
(SC...FC WM): see Fig. 14 - 16.
