Electrical connection
DANGER
Risk of fatal injury due to electrical current!
The use of a thermal overload protection is recommended!
Improper conduct when carrying out electrical work can lead to death due to electric
shock!
• Electrical connection may only be carried out by a qualified electrician and in
accordance with the applicable regulations!
• Adhere to accident prevention regulations!
• Before beginning work on the product, make sure that the pump and drive are
electrically isolated.
• Make sure that no one can turn on the power supply again before work is com-
pleted.
• Make sure that all energy sources can be isolated and locked. If the pump was
switched off by a safety device, it must be secured against switching back on
again until the error has been remedied.
• Electrical machines must always be earthed. Earthing must be appropriate for
the drive and meet the relevant standards and regulations. Earth terminals and
fixation elements must be suitably dimensioned.
• Connection cables must never touch the piping, pump or motor housing.
• If it is possible for persons to come into contact with the pump or the pumped
fluid, the earthed connection must also be fitted with a residual current circuit
breaker.
• Observe the installation and operating instructions for the accessories!
DANGER
Risk of fatal injury due to contact voltage!
Touching live parts will result in serious injuries or death!
Even when it is disconnected, high contact voltages can still occur in the electronic
module due to non-discharged capacitors. Therefore, work on the electronic module
must not be started until 5 minutes have elapsed!
• Disconnect all poles of the supply voltage and secure against reconnection!
• Check whether all connections (including potential-free contacts) are voltage-
free!
• Never insert objects (e.g. nail, screwdriver, wire) into openings on the electronic
module!
• Reinstall removed safety devices (such as module covers)!
DANGER
Risk of fatal electrical shock! Generator or turbine operation during
pump flow!
Even without the electronic module (without electrical connection), there may be
dangerous contact voltage at the motor contacts!
• Close the shut-off devices upstream and downstream of the pump!
DANGER
Risk of fatal electrical shock!
Water on the upper part of the electronic module can enter the electronic module
when it is opened.
• Before opening, remove water, e.g. on the display, by wiping it off completely.
Avoid water penetration in general!
