Installation and operating instructions • Drive for Wilo-Helix2.0-VE / Wilo-Medana CH3-LE • Ed.01/2022-06 83
WARNING
Risk of personal injury!
Opening the motor leads to high, suddenly occurring magnetic forces.
These can cause 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 injury!
Failure to install safety devices on the electronic module or near the
coupling can cause electric shock or contact with rotating parts, po-
tentially resulting in life-threatening injuries.
After maintenance, all safety devices such as module covers or coupling
covers that were removed must be reinstalled!
CAUTION
Risk of property damage!
Risk of damage due to incorrect handling.
The drive may never be operated without the electronic module being
installed.
DANGER
Risk of fatal injury!
The drive itself and drive parts can be extremely heavy. Falling parts
pose a risk of cuts, crush injuries, bruises or impacts, which can be
fatal.
Always use suitable lifting equipment and secure parts against falling.
Never stand underneath a suspended load.
Make sure the drive is securely positioned and is stable during storage
and transport as well as prior to all installation and other assembly work.
DANGER
Risk of fatal injury!
The tools used during maintenance work on the motor shaft can be
flung out if they come into contact with rotating parts, and cause ser-
ious or even fatal injuries.
The tools used during maintenance work must be removed completely
before the drive is started up.
If the transport lugs are moved from the motor flange to the motor
housing, they must be resecured to the motor flange following the in-
stallation or maintenance work.
Air supply
After completion of all maintenance work, reattach the fan cover with the screws provided
so that the motor and the electronic module are sufficiently cooled.
The air supply to the motor housing and module must be checked at regular intervals. In
case of contamination, ensure that an air supply is re-established in order to allow the mo-
tor and electronic module to cool sufficiently.
