Installation Notes

Installation is typically performed by low-voltage technicians or AV integrators during rack assembly or retrofit. Power down and de-energize any active equipment in the rack before attaching or adjusting rear panel components. Follow the manufacturer's mounting instructions for the ERK rack series to ensure proper door alignment and cable clearance. Verify that cable bundles are properly dressed before closing the rear door to avoid pinching or stress on conductors.
