Equipment grounding conductor connection point
Lethal electric shock from live parts with more
than 50 V!
WARNING
Connect the equipment grounding conductor to the equipment grounding
system of the control cabinet.
Check the continuity of the equipment grounding conductors from the mains
connection to the connected motors.
Equipment grounding conductor: material and cross section
Use the same metal (e.g., copper) for the equipment grounding
conductor as for the outer conductors.
Make sure the lines for the connections from the device's equip‐
ment grounding conductor to the equipment grounding conductor
system in the control cabinet are large enough.
For outer conductors with a cross section greater than 16 mm²,
you can reduce the cross section of the equipment grounding
connection according to the table "Equipment grounding conduc‐
tor cross section".
