Fig. 24: Cable shielding
92
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
diameter 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 electronic module. Non-assigned threaded cable con-
nections must remain sealed with the plugs provided by the manufac-
turer.
• 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.
