Electrical Installation
NOTICE!
POTENTIAL EQUALIZATION!
Electrical interference risks disturbing the entire installation when the ground potential between the adjustable
frequency drive and the system is different. To avoid electrical interference, install equalizing cables between the
system components. Recommended cable cross-section: 0.025
