• The power cable is to be fed through the M25 threaded cable connec-
tion (Fig. 22, Item 1).

NOTE:
See the list "Tab. 9: Screw tightening torques" on page 99 for the cor-
rect tightening torques for the terminal screws. Use only a calibrated
torque wrench.
• The following cables must always be shielded, in order to comply with
EMC standards:
• 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.
In the electronic module, the shield is connected in the terminal box
to the earth rails.
• In order to ensure drip protection and strain relief on the threaded cable
connection, cables are to be used which have a sufficient outer diame-
ter and are to be screwed sufficiently tightly. Also, the cables near the
threaded cable connection are to be bent to form a drainage loop, to
drain any accumulated drips. Position the threaded cable connection or
lay the cables accordingly to ensure that no drips can run into the elec-
tronic module. Non-assigned threaded cable connections must remain
sealed with the plugs provided by the manufacturer.
• The connection line is to be installed in such a way that it cannot
under any circumstances come into contact with the pipe and/or the
pump and motor housing.
• When pumps are used in systems with water temperatures above
90 °C, a suitably heat-resistant power cable must be used.
• This pump is equipped with a frequency converter and may not be
protected by a residual-current device. Frequency converters can
impair the function of residual-current-operated protection circuits.
Exception: residual-current devices which have a selective type B
universal-current-sensitive design are allowed.
• Labelling: RCD
• Trigger current: > 30 mA
• Check the current type and voltage of the mains connection.
• Observe the rating plate information for the pump. The current type
and voltage of the mains connection must correspond to the details
on the rating plate.
• Fuse on mains side: max. 25 A
• Take additional earthing into account!
• The use of a miniature circuit breaker is recommended.
