DANGER
Risk of fatal electrical shock!
Before carrying out any work, switch off the power supply and secure it against
being switched on again.
Never open the control module (Fig. I, Item 5) and never remove any operating
elements.
Work on the pump may only be started after 5 minutes have elapsed due to the
dangerous residual contact voltage.
Check whether all connections (including potential-free contacts) are voltage-
free.
Do not operate the pump if the control module/cable is damaged.
If adjustment and operating elements on the control module are removed without
authorisation, there is a risk of electric shock if internal electrical components are
touched.
CAUTION
Material damage caused by improper electrical connection!
If the wrong voltage is applied, the control module can be damaged!

Insulate pump housing only up to the separating gap to the motor!
Keep the condensate drain grooves unobstructed to ensure that condensate
that develops in the motor can drain off without problems!
Electrical work: Electrical work must be performed by a qualified electrician.
The current type and voltage of the mains connection must correspond to the
specifications on the rating plate!
Control via triacs/semiconductor relay is not permitted!
When conducting insulation tests with a high voltage generator, the pump must
be disconnected from the mains at all poles in the system's switch cabinet.
