D301087 0308 - BL20 CANopen7-8
Avoid the use of aluminum components, as its quick oxidizing
properties make it unsuitable for grounding.
PE Connection
A central connection must be established between ground and PE
connection (protective earth).
Earth-Free Operation
Observe all relevant safety regulations when operating an earthfree
system.
Warning
The grounding must never – including cases of error – take on a dan-
gerous touch potential. For this reason, always protect the ground
potential with a protective cable.
