All CADAC products are Common Bonded. This is part of the
design procedure to ensure compliance with the European

(Emissions) and BSEN55103-2 (Immunity).
Common Bonding means a single conductive structure for all
reference, signal and power return currents.

All ‘D sub’ connectors used for external connections should
be purchased with a conductive shell and the cable shield
MUST be bonded to the shell.
