WARNING
Personal injury due to strong magnetic forces!
Opening the motor leads to high, abruptly occurring magnetic forces.
This can lead to serious cuts, crushing injuries and bruises.
• Do not open the motor!
• Only allow Wilo customer service to dismantle and install the motor
flange and the bearing plate for maintenance and repair work!
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!
DANGER
Danger of death from falling parts!
The pump itself and pump parts can have a very high net weight. Falling
parts pose a risk of cuts, crush injuries, bruises or impacts, which can be
fatal.
• Always use suitable lifting accessories and secure parts against falling.
• Never stand below a suspended load.
• During storage and transport, as well as before all installation and as-
sembly work, ensure that the pump is in a safe position and standing
securely.
DANGER
Danger of death due to ejected tools!
The tools used during maintenance work on the motor shaft can be
thrown away if they come into contact with rotating parts. Injuries and
even death are possible!
• The tools used during maintenance work must be removed com-
pletely before the pump is started up!
