DANGER
Fluid temperature
Explosion hazard!
▷ Never operate the submersible mixer at fluid temperatures exceeding those
specified in the data sheet or on the name plate.
DANGER
Fluid temperature
Danger of freezing!
▷ The submersible mixer is designed for operation in liquids. The submersible
mixer is not operational, and therefore must not be operated, under freezing
conditions.
6.2.2.3 Density of fluid handled
The power input of the submersible mixer will increase in proportion to the density
of the fluid handled.
CAUTION
Excessive density of the fluid handled
Overloading of the motor!
▷ Observe the information on fluid density indicated in the data sheet.
▷ Make sure the motor has sufficent power reserves.
6.2.2.4 Abrasive fluids
Do not exceed the maximum permissible solids content specified in the data sheet.
When the mixer is operated in fluids containing abrasive substances, increased wear
of the propeller and the shaft seal are to be expected. In this case, halve the intervals
commonly recommended for servicing and maintenance.
6.2.3 Supply voltage
DANGER
Non-compliance with permissible supply voltage tolerances
Explosion hazard!
▷ Never operate an explosion-proof submersible mixer outside the specified
range.
The maximum permissible operating voltage deviation is ±10%, for explosion-proof
mixers ±5% of the rated voltage. The voltage difference between the individual
phases must not exceed 1%.
6.2.4 Frequency inverter operation
DANGER
Operation outside the permitted frequency range
Explosion hazard!
▷ Never operate an explosion-proof submersible mixer outside the specified
range.
