CE EMC Compliant Cabling
CE EMC compliant cabling is required for all systems shipped to
Europe. All cabling specifications in this chapter conform to the
European CE EMC requirements.
Cable fabrication All of the cables listed on the Cable Selector drawing are CE EMC
compliant when used in an MTS system. Where possible, use standard
cables listed on the System Cable/Jumper Plug 493 Package Selection
drawing (PN 700-000-656). If it is not possible to use standard cables or
you are constructing custom cables, select cables, backshells, and
connection shields as described in the cable specification for each
connector. See the appropriate rear panel connector for fabrication
information.
Low-frequency
ground loops
It is possible that grounding both ends of the overall shield can
produce a low frequency ground loop current. If you experience an
unacceptable low-frequency noise level, try the following in the order
given:
• Connect the system (chassis) ground of the external device
directly to the controller chassis.
• Disconnect the overall shield from the metallized back shell at the
external device and add a capacitor (approximately 0.01
µf) to
that end of the cable between the shield and the metallized
backshell.*
• Disconnect the overall shield from the metallized back shell at the
external device.*
* This action may compromise EC EMC compliance.
