PE connection

DANGER

Danger to life from electrical shock!

In the event of an interruption to the PE connection, avoid touching the casing because life-threatening levels of voltage may be present!

Steps to prevent:

  • EN 61800-5-1 requires that the devices be firmly connected on the power side.
  • The PE conductor must have a cross-section of at least 10 mm2 or must have a second PE connection with a cross-section at least equal to the mains feeder (cf. EN 61800-5-1).
Cross-section AC wire Cross-section PE wire
≤ 10 mm2 = 10 mm2
10 ... 16 mm2 = Cross-section AC wire
16 ... 35 mm2 = 16 mm2
≥ 35 mm2 ≈ 1/2 x Cross-section AC wire

 

Description:

The PE connection is a screw bolt on the module casing (see front view) for attaching PE lines and cable shields.

Configure as follows:
