DANGER!

Electrical danger!
Improper connection of the pump−motor unit
can result in an electric shock.

Observe the following basic rules:
 The leakage current to earth (PE) is

>3.5 mA. The PE connection must meet EN
50178.

 Observe national and regional regulations.

CAUTION

Danger of pump−motor unit damage caused
by improper connection!
Observe the permissible mains voltage. Any
higher mains voltage will destroy the frequency
inverter.

Wiring according to EMC requirements
(installation of a CE-typical drive system)

The pump−motor units meet the EU Directive on
"Electromagnetic Compatibility" if they are
installed in accordance with the specifications of
the CE−typical drive system. The end−user is
responsible for maintaining the EU Directive in
the overall system.

NOTE

Requirements for trouble−free operation:

 Always shield control cables.
 Provide large−surface contact between

shielding and shield sheet. Ensure good
electrical contact.
