Earth-leakage currents ≥ 3.5 mA can occur during normal operation. Observe the follow-
ing for reliable PE connection:
• Supply system lead < 10 mm
2
:
– Route a second PE conductor with the same cross section as the supply system
lead in parallel to the protective earth via separate terminals, or
– use a copper protective earth conductor with a cross section of 10 mm
2
• Supply system cable 10 – 16 mm
2
:
– Copper protective earth conductor with the cross section of the supply system
lead.
• Supply system cable 16 – 35 mm
