• Some field wiring needs shielded (screened) cable. There can be a Shield
Ground and the AC Safety and Instrument Grounds to provide a
common point to terminate cable shields.
Connect the adapter base unit ground stud to the AC safety ground bus bar of
the system:
• Use an M6 lug on the end of the ground wire.
• Place the lug below the second nut on the ground stud between two
washers and use two 10 mm (.039 in.) wrenches to tighten the nuts.
• Use a minimum conductor wire size of 4 mm

Connect the field wiring to the screw terminal blocks on the termination
assemblies.
IMPORTANT The termination assemblies have integral fuses.
IMPORTANT You must use safety wiring principles if the applicable standards
for the system require you take precautions to avoid external
short circuits, because the internal diagnostics in the 1715
adapter do not detect external short circuits between channels.
These standards include NFPA-72.
