Field Installation Guidelines Install the SEC401-11 on a grounded ESB backplane rail assembly. Ensure connector alignment is fully seated to maintain bus continuity across adjacent modules. Avoid mechanical stress on bus coupling interfaces during insertion. Shield grounding must be maintained at cabinet frame level to minimize electromagnetic coupling interference across high-speed backplane traces. Do not exceed rated module population per ESB segment to preserve deterministic communication timing.
