(2) Precautions
This section describes wiring precautions.
(a) Handling
• Place the Ethernet cable in a duct or clamp them. If not, dangling cable may swing or inadvertently be pulled,
resulting in damage to the module or cables or malfunction due to poor contact.
• Do not touch the core of the cable-side or module-side connector, and protect it from dirt or dust. If oil from
your hand, dirt or dust is attached to the core, it can increase transmission loss, arising a problem in data
link.
• Check the following:
• Is any Ethernet cable disconnected?
• Is any of the Ethernet cables shorted?
• Are the connectors securely connected?
• When the Ethernet cable is connected, refer to the CC-Link IE Field Network Cable Installation Manual
which is available from the website of CC-Link Partner Association (www.cc-link.org). Failure to do so may
result in malfunction due to incorrect installation of the cable.
(b) Broken cable latch
Do not use Ethernet cables with broken latches. Doing so may cause the cable to unplug or malfunction.
(c) Connecting and disconnecting the Ethernet cable
Hold the connector part when connecting and disconnecting the Ethernet cable. Pulling a cable connected to
the module may damage the module or cable, or result in malfunction due to poor contact.
(d) Connectors without Ethernet cable
Attached connector cover should be placed to prevent foreign matter such as dirt or dust.
(e) Maximum station-to-station distance (maximum cable length)
The maximum station-to-station distance is 100m. However, the distance may be shorter depending on the
operating environment of the cable. For details, contact your cable manufacturer.
(f) Bend radius
The bend radius of the Ethernet cable is limited. For details, see the specifications of the Ethernet cable to be
used.
(g) Network configuration
For wiring, check Page 49, Section 5.2.1 (1), Page 54, Section 5.2.3 (2) to prevent incorrect wiring.
