2. Wiring Outside of the Control Cabinet
If a VARAN bus cable must be placed outside of the control cabinet only, no additional
shield connection is required. This requires that only IP67 modules and connectors be
used. These components are very robust and noise resistant. The shielding for all sockets
in IP67 modules are internally connected to common bus or electrically connected to the
housing, whereby the deflection of voltage spikes does not flow through the electronics.
