3.3.3 Earthing
Every DE1 variable speed starter must be individually connected to the
power supply system's protective earth directly at the location of installation
(system earthing). This protective earth must not pass through any other
devices.
All protective earth conductors must be routed in a star-shaped layout
extending from the central earth point, and all of the power drive system's
conductive components (DE1 variable speed starter, mains choke, motor
choke, sine filter) must be connected.
The earth-fault loop impedance must comply with all locally applicable
industrial safety regulations. In order to meet UL requirements, UL-listed ring
cable lugs must be used for all earth wiring connections.

Avoid ground loops when installing multiple variable speed
starters in one control panel. Make sure that all metallic devices
that are to be grounded have a broad area connection with the
mounting plate.

In the case of variable speed starters with an internal
interferenceradio interference suppression filter, the PE cable
(DE1-…FN-…) must be inserted behind the EMC jumper
(when viewing the connection terminals.
