Installation and operating instructions SIE, DIE, PBE
• With a horizontal motor shaft, the condensate hole must be posi-
tioned towards the bottom (Fig 18, Item 2). If necessary, the motor
must be turned accordingly.
NOTE:
If the plastic plug is removed, protection class IP 55 is no longer ensured.
NOTE:
In the case of insulated systems, only the pump housing may be insu-
lated, not the lantern, drive and differential pressure sensor.
An insulating material which does not contain ammonia compounds
must be used when insulating the pump, in order to prevent stress cor-
rosion cracking of the union nuts. If this is not possible, direct contact
with the brass screw connections must be avoided. Stainless steel
screwed connections are available for this as an accessory. As an alter-
native, corrosion protection tape (e.g. insulating tape) can also be used.
DANGER! Risk of fatal injury!
Incorrect electrical connections can cause fatal electric shocks.
• Have the electrical connection set up by an electrician approved by
the local electricity supplier only and in accordance with local
regulations.
• Observe the installation and operating instructions for the
accessories!
DANGER! Risk of fatal injury!
Contact voltage hazardous to human life.
Work on the electronic module may only be started once 5 minutes
have passed, due to the dangerous residual contact voltage
(capacitors).
• Before working on the pump, disconnect the power supply and
wait for 5 minutes.
• Check whether all connections (including potential-free contacts)
are voltage-free.
• Never use an object to poke around the openings on the electronic
module and never insert anything into the terminal box!
WARNING! Risk of mains overload!
An inadequate mains design can lead to system failures and cable
fires due to mains overload.
• When designing the mains, with regard to the cable cross-sections
and fuses, give special consideration to the fact that short-term
simultaneous operation of all pumps is possible in multi-pump
operation.
NOTE:
Requirements and limit values for harmonic currents:
Pump of power classes 11 kW, 15 kW, 18.5 kW and 22 kW are devices
for professional use. These devices are subject to special connection
conditions, as an R of 33 at the connection point is insufficient to
sce
operate them. Connection to the public low voltage power supply is
regulated via standard IEC 61000-3-12 - the basis for the evaluation
of the pumps is table 4 for three-phase devices under special condi-
tions. For all public connection points, the short circuit output S
the interface between the electrical installation of the user and the power supply must be greater than or equal to the values listed in the
table. It is the responsibility of the installer or user, if necessary with
the assistance of the power operator, to ensure that these pumps are
operated properly. During industrial use in a plant-specific, medium-
