Severe or fatal injuries.
  • The permitted tightening torque for the screw is 2.0 to 2.4 Nm.
  • Observe the following notes for the PE connection.

Not permitted mounting

Recommendation:

Installation with forked cable lug

Forked cable lug suitable for M5 PE screws

During normal operation, leakage currents ≥ 3.5 mA may occur. In order to fulfill EN 61800-5-1, observe the following information:

  • The ground connection (PE) must be installed so that it meets the requirements for systems with high leakage currents.
  • This usually means
    • Installing a PE connection cable with a minimum cross section of 10 mm2
    • or installing a second PE connection cable in parallel to the protective earth.
