Fig. 24: Cable shielding

In electronic modules with a motor power < 5.5 kW, the shield in the
electronic module is connected in the terminal box to the earth rails.
In electronic modules with a motor power of 5.5 kW and 7.5 kW, the
shield is connected to the cable bushing. In electronic modules with
motor power ≥ 11 kW, the shield is installed on the cable terminals
above the terminal strip. The various procedures for connecting the
shield are shown schematically in Fig. 24.
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 (< 11 kW) > 30 mA
• Trigger current (≥ 11 kW) > 300 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. permitted see following table; refer to the
rating plate data.
