Cabling and Using External Readout Devices
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.
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 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.
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.
