External Wiring
Wiring, and noise countermeasures in particular, are based on experience, and it is necessary to
closely manage wiring based on experience and information in the manuals.
Wiring Routes
Each of the following combinations includes different signal types, properties, or levels. They will
cause the signal-to-noise ratio to drop due to factors such as electrical induction. As a general rule
when wiring, either use separate cables or separate wiring routes for these items. Future mainte-
nance operations and changes to the system will also be made easier by carefully organizing the
wiring from the start.
• Power lines and signal lines
• Input signals and output signals
• Analog signals and digital signals
• High-level signals and low-level signals
• Communications lines and power lines
• DC signals and AC signals
• High-frequency devices (such as Inverters) and signal lines (communications)
(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.

• To avoid overheating the conduits when using conduits for wiring, do not place wires for a single
circuit in separate conduits.
