(Routing of) Wiring
Observe the following points when wiring power supply and signal cables.
• When routing signal cables with differing characteristics through the same duct, always keep
them separated.
• As much as possible, avoid routing multiple power supply lines through the same duct. If it can-
not be avoided, then construct a partition between them in the duct and ground the partition.
