With the installation of an appropriate harmonic filter between the
pump and the mains power supply reduces the level of harmonic cur-
rent.
• The electrical connection must be made using a permanently installed
mains connection line (see following table for cross-section) with a
plug-and-socket connection or an all-pole switch with a contact
opening width of at least 3 mm . If flexible cables are used, ferrules
must be used.
• The power cable must be passed through the threaded cable connec-
tion M25/M40 (Fig. 23, no. 1).

NOTE:
See Table 10 "Screw tightening torques" on page 112 for the correct
tightening torques for the terminal screws. Use only a calibrated
torque wrench.
• In order to comply with electromagnetic compatibility standards, the
following cables must always be shielded:
• Differential pressure sensor (DDG) (if installed onsite)
• In2 (setpoint)
• Dual-pump (DP) communication (for cable lengths > 1 m); ("MP"
terminal)
Note the polarity:
MA = L => SL = L
MA = H => SL = H
• Ext. off
• AUX
• Communication cable IF-Module
The shield must be applied to both sides: on the EMC cable clips in the
electronic module and on the other end. The lines for SBM and SSM do
not have to be shielded.
