Safety
DANGER! Risk of fatal injury!
Incorrect installation and improper electrical connections can be
life-threatening.
• Have the electrical connections set up by qualified electricians
only, in compliance with the applicable regulations!
• Adhere to accident prevention regulations!
DANGER! Risk of fatal injury!
Failure to install safety devices on the electronic module or near
the coupling/motor can cause electrical shock or contact with
rotating parts, potentially resulting in life-threatening injuries.
• Before commissioning, all safety devices such as module covers or
coupling covers that were removed must be reinstalled!
DANGER! Risk of fatal injury!
Potentially fatal injury due to electronic module not being
installed!
• Normal operation of the pump is only permitted with the electronic
module installed.
• The pump must not be connected up or operated without the elec-
tronic module being installed.
DANGER! Risk of fatal injury!
The pump itself and pump 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 pump is securely positioned and is stable during
storage and transport as well as prior to all installation and other
assembly work.
CAUTION! Risk of material damage!
Risk of damage due to incorrect handling.
• Have the pump installed by qualified personnel only.
• The pump must never be operated without the electronic module
being installed.
CAUTION! Damage to the pump due to overheating!
The pump must not be allowed to operate dry for more
than 1 minute. Dry running causes a build-up of energy in the
pump, which can damage the shaft, impeller, and mechanical seal.
• Make sure that the volume flow does not fall below the minimum
value Q
