Wiring Of Network Cable - Mitsubishi Electric NZ2FTGN User Manual

Wiring of network cable

This section describes how to connect and disconnect the network cable.
Ethernet cable
■Connection
1.
Power off the module.
2.
Push the Ethernet cable into the coupler until it clicks. Pay attention to the orientation.
3.
Power on the module.
4.
Power on the external device.
5.
Check that the P1 LINK LED or P2 LINK LED on the port to which the Ethernet cable is connected are on.
The names of the LINK LEDs on each coupler are as follows.
Model
NZ2FT-GN
NZ2FT-PN
NZ2FT-MT
NZ2FT-EIP
The time taken for the LINK LED to turn on after connection of the Ethernet cable may vary, but normally it lights up in a few
seconds. However, if link-up processing is repeated due to a condition of device on the line, a longer time may be needed.
If the LINK LED does not turn on, refer to the troubleshooting, and take corrective actions.
Both P1 and P2 can be used.
• When only one connector is used in star topology, either P1 or P2 can be connected.
• When both connectors are used in line topology and ring topology, connecting P1 to P1 and P2 to P2 (1)
and connecting P1 to P2 (2) are possible.
■Removal
Power off the module, and pull out the Ethernet cable while pressing the latch down.
■Wiring precautions
• Do not touch the core of P1 or P2 of the Ethernet cable. In addition, prevent dirt or dust from adhering to the core. Adhesion
of oil from your hand, dirt, or dust to the core can increase transmission loss, causing data link to fail.
• Check the Ethernet cable for disconnection, short-circuit, and problems with P1 or P2 connection.
• Do not use Ethernet cables with broken latches. Doing so may cause the cable to unplug or malfunction.
• In a severe noise environment, attach a ferrite core to the Ethernet cable. In a more severe noise environment, attach two
identical ferrite cores.
Recommended ferrite core: E04SR401938 (SEIWA ELECTRIC MFG. CO.,LTD.), E04SR482648 (SEIWA ELECTRIC MFG.
CO.,LTD.)
