Use suppression devices for additional noise protection. The
suppression devices can be added at the external source.
Appropriate suppression devices are commercially available.
Grounding wires for routing
Wires that carry relatively high electrical energy can produce
unwanted noise in wires that transmit signals of relatively low energy,
particularly when they are placed parallel in long wiring runs.
Collect and bundle wires of similar type, and route the bundle
separate from bundles of other types. The following table provides
suggested guidelines for grouping wires.
Table 6-2: Guidelines for grouping wires
Wire Group
Wire Functions
High voltage (>50 Vdc/VAC)
AC Line power wiring
Signal (<15 Vdc)
Analog signal wire, such as:
Low voltage (<50 Vdc/VAC)
Low voltage alarm relay output wiring
Wiring and cabling distance guidelines
Two network topologies are supported in I/O network: Ring and Star.
n
For Ethernet connections, cable length must be less than 100 m.
The use of Ethernet cables in excess of 100 meters and/or devices
other than recommended switches will cause transmission delays
on the I/O link which could have adverse effects on CPM
performance.
ATTENTION: Shielded Ethernet cables are required for I/O
link.
n
For greater than 100 m, a fiber optic cable is recommended with a
fiber switch or fiber optic converter.
n
If a multi-mode fiber optic cable connects to a MOXA unmanaged
Ethernet Switch or similar devices, the distance of the cable is up
to 5km. See
section for more
information.
