Fig. 23: Cable shielding
94
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. 23.
In order to ensure drip protection and strain relief on the threaded
cable gland, cables are to be used which have a sufficient outer diam-
eter and are to be screwed sufficiently tight. Also, the cables near the
threaded cable gland are to be bent to form a drain loop, to drain any
accumulated drips. Position the threaded cable gland or lay the cables
accordingly to ensure that no drips can run into the electronic module.
Non-assigned threaded cable glands must remain sealed with the
plugs provided by the manufacturer.
• The connection cable 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 mains connection 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: FI
• Trigger current: > 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 specifi-
cations on the rating plate.
• Fuse on mains side: max. permitted see following table; refer to the
rating plate data.
