Field Installation Guidelines

Verify cabinet power isolation before module replacement or installation. Use ESD protection equipment when handling the circuit board assembly. Install the module into the assigned exciter backplane slot or DIN-rail mounting position according to rack configuration requirements.

Route Ethernet, ISBus, and serial cables separately from high-voltage power conductors to reduce electromagnetic interference. Ensure cable shielding is connected according to cabinet grounding practices. Confirm backplane seating, connector engagement, and firmware compatibility before system energization.
