Installation and operating instructions SIE-DIE-PBE

• The electrical connection must be made using a plug-and-socket
connection or an all-pole switch with a contact opening width of at
lease 3 mm. The power cable must be passed through the threaded
cable connection M25/M40 (Fig. 19, no. 1).

• The following cables must always be shielded, in order to comply with
EMC standards:
• DDG (if installed on-site)
• IN2 (setpoint)
• DP communication (for cable lengths > 1 m); (terminal "MP")
Comply with polarity:
MA = L => SL = L
MA = H => SL = H
• Ext. Off
• AUX
• Communication cable IF-Module
The shield must be connected at both ends, on the EMC threaded
cable connection on the module and at the other end. The lines for
SBM and SSM do not have to be shielded.
In modules with a motor power < 5.5 kW, the shield in the module is
connected in the terminal box to the earth bars. In modules with a
motor power of 5.5 kW and 7.5 kW, the shield is connected to the
cable bushing. In 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. 20.
• In order to ensure drip protection and strain relief on the threaded
cable connection, cables with a sufficient outer diameter must be
used and must 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 connec-
tion or lay the cables accordingly to ensure that no drips can run into
the module. Non-assigned threaded cable connections must remain
sealed with the plugs provided by the manufacturer.
• The connection line is to be placed in such a way that it can under no
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 connection line must be used.
• This pump is equipped with a frequency converter and may not be
protected by a residual-current-operated protection circuit. Fre-
quency converters can impair the function of residual-current-oper-
ated protection circuits.
Exception: residual-current-operated protection circuits which have
a selective type B universal-current-sensitive design are allowed.
