See detail above. The following steps are performed on each EL that is physically on site. If you are building the
network off site, these steps are completed after mechanical installation and during network commissioning.
1. Connect network cable to the EL 'Network' terminals. Two wires are required. A twisted pair is most commonly
used. The free topology FTT-10 transceiver can be used in bus, loop, star and daisy chain topologies. Two
RJ-45 terminals and one screw terminal on the EL allow for daisy chaining or temporarily connecting to a
computer.
