Fuse on mains side

DANGER
Risk of fatal injury due to contact voltage!
Even when enabled, high contact voltages can still be present
in the electronic module due to undischarged capacitors.
Therefore, work on the electronic module must not be started
until 5 minutes have elapsed!
Touching live parts will result in serious injuries or death!
• Before working on the pump, disconnect all poles of the supply
voltage and secure against being switched on again! Wait 5 minutes.
• 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)!
WARNING
Risk of mains overload! An inadequate mains design can lead to
system failures and cable fires due to mains overload.
Short-term simultaneous operation of all pumps is possible in multi-
pump operation.
Take multi-pump operation into account when designing the network,
especially with regard to the cable cross-sections and fuses used. Each
drive must have its own supply line with separate fuse protection!
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!
• Check for absence of voltage and cover or cordon off adjacent live
parts!
• Close the shut-off devices upstream and downstream of the pump!
DANGER
Potentially fatal injury due to electronic module not being in-
stalled!
A life-threatening voltage may be present at the motor contacts!
Normal operation of the pump is only permitted with the electronic
module installed.
• Never connect or operate the pump without the electronic module
mounted!
CAUTION
Danger of material damage caused by improper electrical con-
nection!
• Ensure that the current type and voltage of the mains connection cor-
respond to the specifications on the pump rating plate.
The fuse protection on mains side must always match the electrical design of the pump!
Comply with the regulations of the local energy supply company!
Maximum permissible fuse protection, see following table; observe the rating plate data!
