Precautions
■Laying Ethernet cables
• Place the Ethernet cable in a duct or clamp them. If not, a dangling cable may swing or inadvertently be pulled, resulting in
damage to the NZ2GN-GFB or cables or malfunction due to erroneous operation.
• 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.
• For the Ethernet cables to be used, check that they are not disconnected or short-circuited and that there is no problem
with connector connection.
■Broken Ethernet cable latch
Do not use Ethernet cables with broken latches. Doing so may cause the cable to unplug or malfunction.
■Connecting and disconnecting the Ethernet cable
Hold the connector part when connecting and disconnecting the Ethernet cable. Pulling the cable connected to the NZ2GN-
GFB may result in damage to the NZ2GN-GFB or cables or malfunction due to erroneous operation.
■Connectors without Ethernet cable
Attach a connector cover to prevent dirt and dust from entering the NZ2GN-GFB module and to prevent module failure and
malfunction caused by static electricity.
■Maximum segment length for the Ethernet cable (Maximum cable length)
The maximum segment length for the Ethernet cable 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.
