Safety
DANGER! Risk of fatal injury!
Incorrect installation and improper electrical connections can
result in fatal injury.
• Have the electrical connections established by approved electri-
cians only, in compliance with the applicable regulations.
• Observe the accident prevention regulations!
DANGER! Risk of fatal injury!
Failure to install safety devices on the module cover or near the
coupling 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!
CAUTION! Risk of material damage!
Danger of damage due to incorrect handling.
• Have the pump installed by qualified personnel only.
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 go below the minimum
value Q
min
.
