This section explains how to connect the QJ71MT91 to the 100BASE-TX or 10BASE-T
network.
(1) Connection precautions
The following are the precautions for connection of the QJ71MT91.
Handle the QJ71MT91 correctly, paying full attention to safety.
 Sufficient safety measures must be taken for 100BASE-TX or 10BASE-T
installation work.
Consult a specialist, including when connecting cable terminals or installing trunk
line cables.
 Use the connection cable, which complies with the corresponding standard given
in Section 3.1.
 Do not install the control lines or communication cables together with the main
circuit lines or power cables.
Keep a distance of at least 100mm between them.
Failure to do so can cause a malfunction due to noise.
 Place the cables 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. In addition, the weight of the cables may put
stress on modules in an environment of strong vibrations and shocks.
 When disconnecting the cable from the module, do not pull the cable by the cable
part.
Disconnect the cable by holding the connector connected to the module.
Pulling the cable connected to the module may result in malfunction or damage
to the module or cable.
