6.5 Ground connection

6.5.1 Earthing equipotential connection

The equipotential connection must be carried out
using an external cable with a minimum 4mm²
section (11AWG).
Connect the cable for the earthing equipotential
connection with the eyelet terminal supplied
(suitable for cables with 4mm² (11AWG) up to 6mm²
(9AWG) section).
Fasten the eyelet using the screw (M5) and lock
washer
Characteristics of the M5 screw:
• Material: A4 Class 70
• Screw head: ISO 4762
• Length: 8mm (0.3in)
