Check the alignment of the unit again as described in chapter 7.1
"Installation" on page 40.
• Tighten the foundation bolts if necessary.
• Check all connections for correctness and function.
• It must be possible to turn the coupling/shaft by hand.
Do not allow the coupling/shaft to turn:
• Release the coupling and re-tighten with the prescribed torque.
In case this measure is not successful:
• Remove the motor (see chapter 9.2.3 "Changing the motor" on
page 52).
• Clean the motor centring and flange.
• Reinstall the motor.
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 terminal box may only be started once 5 minutes have
passed, due to the dangerous residual contact voltage (capacitors).
• Before working on the pump, disconnect the supply voltage 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 terminal
box and never insert anything into the terminal box!
WARNING! Risk of mains overload!
An inadequate mains design can lead to system failures and even to
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.
• The electrical connection must be made in accordance with
VDE 0730/part 1 via a fixed mains connection cable, which is provided
with a plug device or an all-pole switch with a contact opening width
of at least 3 mm.
• 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.
• To get rid of any drips that accumulate, the cables are to be bent into
a drain loop near the threaded cable connection.
• By positioning the threaded cable connection or by laying the cables
accordingly, ensure that no drips can enter the terminal box. Non-
assigned threaded cable connections must remain sealed with the
plugs provided by the manufacturer.
• The connection pipe 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.
