The following are provided on the device:
FE connection in power supply connector as EMC filter reference potential
•
ATTENTION
This connection is necessary in order to comply with EMC requirements.
a PE earthing lug in the service slot
•
Recommendation for use:
When possible, FE and PE should be connected to the central earthing rail
via separate cable lines.
Conductor cross sections:
PE: ≥ AWG 16 (≙ 1.5 mm
•
FE: AWG 18 (≙ 0.75 mm
