6.6 Second protective grounding connection
If additional grounding or equipotential bonding is required
locally, you can connect additional grounding to the inverter. This
prevents touch current if the grounding conductor on the AC
connector fails.
Procedure:
1. Insert the grounding conductor into the suitable terminal lug
and crimp the contact.
2. Align the terminal lug with the grounding conductor.
3. Insert the screw through the hole located at the housing and
tighten it firmly (screwdriver type: PH2, torque: 1.6Nm).
