(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 Ethernet cable 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) 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.
(e) Bend radius
The bend radius of the Ethernet cable is limited. For details, see the specifications of the Ethernet cable to be
used.
