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 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 one end of the cable
between the shield and the metallized backshell.
• Disconnect the overall shield from the metallized back shell at the external
device.
