Wiring the Terminal
3.1 Cabling requirements
Table 6 outlines recommended cabling requirements for each connector on the emerald.
3.1.1 Ethernet host
Ethernet communications should be cabled & terminated for 100Base-T operation according to
IN ANSI/TIA/EIA-568-A / TIA/EIA-568-B. In order to comply with FCC requirements, a snap-on
ferrite (Wurth Electronics 74272722 or equivalent) should be used around the Ethernet cable.
Due to limited space, additional care should be taken when using CAT6 connectors or CAT5
connectors with a strain relief boot at the terminal. There should be enough spare cable left
within the enclosure/back box to allow a service engineer to open the terminal case without
straining the RJ45 connector. Where the cable is subject to movement or vibration, stranded
Ethernet cable (and appropriate connectors) should be used.

a. As a guideline, a typical maglock from 650mA up to 1500mA @ 12V would use AWG18
cable, located no more than 7.6m (25’) from the emerald™ terminal. Cables should not
exceed 30m (98.4’) in length.
Note
22AWG is the smallest acceptable cabling for a UL-294 installation, cable
