CE Installation Guide
Overview
For CE compliance, wiring schemes described in this CE
Installation chapter must be followed. For CE
installations, wiring schemes described in this chapter
supersede wiring schemes described in other chapters.
Wiring scheme specific to CE installations are outlined
below.
For CE installation, the MCT(s) must be installed in a
metal enclosure that provides shielding to the sides, door
and rear by being grounded to protective earth. The
earth-ground bond must be made using a heavy gauge
copper-braid cable or copper bus bar in a manner that
will ensure a continuous, high-quality connection.
Signal and dc power I/O cabling for the system should be
enclosed in rigid or flexible metal conduit that is bonded
to earth-ground. If an ac / dc supply is included inside
the enclosure, the ac input power cabling must enter the
enclosure through a conduit separate from the one used
for dc power and I/O signals.
If the system is to be powered by an external dc power
source, the cable connecting the dc power to the system
must utilize a twisted-shielded-pair cable of an
appropriate gauge. The cable-shield must be connected
to system ground at one end only.
The system dc ground should be connected to earth-
ground at only one point in the system; typically by
