■Laying Ethernet cables
• 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 connector of the cable or the module, and protect it from dirt and dust. If any oil from your hand,
or any dirt or dust sticks to the core, it can increase transmission loss, causing data link to fail.
• Check the following:
• Is any Ethernet cable disconnected?
• Does any Ethernet cable short?
• Are the connectors securely connected?
■Connecting and disconnecting the Ethernet cable
Hold the connector part when connecting and disconnecting the Ethernet cable. Pulling the cable connected to the module
may result in damage to the module or cable or malfunction due to poor contact.
■Connectors without Ethernet cable
To prevent dust from entering the module, attach the provided waterproof caps.
■Maximum station-to-station distance (Maximum Ethernet 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 the manufacturer of the cables used.
■Bending radius of the Ethernet cable
There are restrictions on the bending radius of the Ethernet cable. Check the bending radius in the specifications of the
Ethernet cables used.
Attaching Waterproof Caps
Tighten the waterproof caps within the following torque range.
Power off the module.
Loosen the screw of the Ethernet cable and
