13.2 Wiring Outside of the Control Cabinet
If a bus line must be connected outside of the control cabinet only, no additional shield
support is required. A requirement therefore, is that only IP67 modules and connectors can
be used outside the control cabinet. These components are very robust and noise resistant.
The shielding for all sockets in IP67 modules are electrically connected internally or over
the housing, whereby voltage spikes are not dissipated through the electronics.
