Does the little screw on the side of the Victron Smart 100/30 MPPT Solar Charge Controller need grounding to chassis?

Cheers all

4.4. Grounding

Battery grounding

The solar charger can be installed in a positive or in a negative grounded system.

Apply a single ground connection, preferably close to the battery, to prevent system issues or ground loops.

Chassis grounding (only for the 30A model)

A separate ground path for the chassis ground is permitted because the chassis is isolated from the positive and the negative terminals.
