order to wash away any residues (chips, shavings, sawdust) due to the setup work.
Electrical preparation
Mains connection
CAUTION
Only qualified electricians are permitted to perform electrical installations!
ATTENTION
Make sure the electrical supply capacity is in accordance with the electrical characteristics of
the NetaFlex™ 3G.
Make sure the short-timed higher current consumption when starting up the system pump was
taken in consideration (for further details see the enclosed Pump Documentation).
The following components have to be provided in the installation:
• A readily accessible circuit breaker, rated according to the NetaFlex™ 3G's total rated power for peak
demand, certified as a branch circuit over current protector (see System Pump List , page 28),
compliant with the national code and requirements.
• Grounding connection: ≤ 10 Ω.
For the selection of the supply wire size - consider (see System Pump List , page 28):
• The NetaFlex™ 3G's total rated power.
• Whether the electricity supply is single-phase or three-phase.
