The submersible mixer is supplied with a power cable. Always connect all marked
cores.
DANGER
Operating an incompletely connected submersible mixer
Explosion hazard!
▷
Never start up a submersible mixer with incompletely connected power cables
or non-operational monitoring devices.
DANGER
Incorrect wiring
Explosion hazard!
▷
The connection point of the cable ends must be located outside the potentially
explosive atmosphere or inside electrical equipment approved to equipment
category II2G.
CAUTION
Flow-induced motion and layers of floating sludge in biogas installations
Damage to the power cable!
▷
Run the power cable upwards with as little slack as possible and protect, if
necessary.
NOTE
We recommend to use cable supports available as accessories for properly fastening the
electrical cable at the tank edge.
1. Run the power cable directly upwards (if possible) without slack, and fasten.
2. Only remove the protective caps from the power cable immediately before
connection.
3. If necessary, adjust the length of the power cable to the site requirements.
4. After shortening the cable, correctly re-affix the markings on the individual cores
at the cable end.
The submersible mixer does not have an external PE connection (risk of corrosion).
DANGER
Incorrect wiring
Explosion hazard!
▷
Explosion-proof submersible mixers installed in a tank must never be retrofitted
with an external potential equalisation connection!
DANGER
Touching the submersible mixer during operation
Electric shock!
▷
Make sure that the submersible mixer cannot be touched during operation.
