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