The following are guidelines for setting up the plant wiring and cabling at your site.
When planning the location of the new system, consider the distance limitations
for signaling, Electromagnetic Interference (EMI), and connector compatibility, as
described in the sections below:

NTERFERENCE
ONSIDERATIONS
Interference can occur when wires are run for any significant distance in an
electromagnetic field. To prevent damages caused by interference, do the
following:
Ensure that there is no radio interference emanating from the plant wiring.
Ensure that there is no electrical hazard by conducting power surges through lines
and into equipment caused by EMI.
Use a high-quality twisted-pair cable with one ground conductor for each data
signal, when applicable.
Give special consideration to the effect of a lightning strike near the system
location. The electromagnetic pulse caused by lightning or other high-energy
phenomena can destroy electronic devices.

IMITATIONS AND
The size of your network and the distances between connections depend on the
signal type, speed, and transmission media. For example, standard coaxial cable
has a greater channel capacity than twisted-pair cable.
When preparing your site for network connections to the OA-740, you should
consider the following:
Type of cabling required (fiber, shielded twisted-pair, or unshielded twisted-pair).
Distance limitations.
Cables needed for interface connections.
Any additional interface equipment required, such as transceivers, hubs,
switches, modems, etc.

RECAUTIONS TO BE
AKEN
Follow these precautions and recommendations when planning power
connections to the OA-740:
Check the power at your site before installation and periodically after installation
