Risk of fatal injury due to electrical current!
Improper conduct when carrying out electrical work can lead to death due to electric
shock!
• Any work on electrical devices may only be carried out by a qualified electrician.
• Before carrying out any work, disconnect the unit from the power supply and se-
cure it against accidental switch-on.
• Any damage to the pump connection cable should only ever be rectified by a
qualified electrician.
• Never poke around in the openings of the motor or electronic module or insert
anything into them.
• Follow the installation and operating instructions for the pump, level control
device and other accessories.
• After completing the work, refit previously dismantled protective devices, for ex-
ample, covers or coupling covers.
DANGER
When dismantled, the permanent magnet rotor inside the pump can pose mortal
danger for people with medical implants (e.g. pacemakers).
• Follow the general behavioural guidelines that apply to handling electrical
devices!
• Do not open the motor!
• Dismantling and installation of the rotor may only be carried out by Wilo cus-
tomer service! If you have been fitted with a pacemaker, you must not carry out
this kind of work!
NOTICE
The magnets inside the motor do not pose a danger provided the motor is com-
pletely assembled . Persons with pacemakers can approach a Yonos GIGA2.0 without
restriction.
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!
