    In typical industrial systems, the ground bus is mounted on the back panel of the enclosure. The protective earth and functional earth terminals of the various equipment in the enclosure are connected to the ground bus bar. Rockwell Automation Publication 2711P-TD001D-EN-P - February 2011...
  • Page 4: Wiring And Safety Guidelines

    Do not connect or disconnect components unless power has been switched off. All wiring must comply with N.E.C. articles 501, 502, 503, and C.E.C. section 18-1J2, as appropriate. Peripheral equipment must be suitable for the location it is used in. Rockwell Automation Publication 2711P-TD001D-EN-P - February 2011...
