Transceiver Installation Precautions
•
Transceivers can be attached to coaxial cables only at intervals of 2.5 m. These locations should be marked on
the cable.
•
Connection methods can vary with the manufacturer of the cable. Follow all recommendations and specifica-
tions of the manufacturer.
•
Mount the transceiver onto an insulating object, such as a wooden board.
•
Ground the transceiver through the shield of the transceiver cable and through the Ethernet Unit.
•
Do not install transceivers near sources of noise.
•
Do not install coaxial cable in environments subject to excessive dirt, dust, oil mist, etc.
•
Do not install coaxial cable in environments subject to high temperatures or high humidity.
Transceiver Cable Installation Precautions
•
Make sure that the transceiver cable is firmly and completely connected to both the transceiver and the Ethernet
Unit. Be sure that the slide latches are engaged.
•
Do not install transceiver cables together with power cables.
•
Do not install transceiver cable near sources of noise.
•
Do not install transceiver cable in environments subject to high temperatures or high humidity.
Grounding
•
Ground all devices requiring grounding to 100
W
or less using AWG 14 wire (cross-sectional area of 2 mm
2
) or
better and a ground cable length of 20 m or less. Electrical shock can occur between ungrounded devices in the
system. The lack of proper grounds can also corrupt data.
•
Use one safety ground on each segment of the network.
•
Inductive voltages can be generated due to lightning surges when coaxial cable is installed outdoors, requiring
special measures. Request outdoor installation from a professional.
