(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?
(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 5.1.1 (2) and Page 51, Section 5.1.1 (3) to prevent incorrect wiring
