  • Page 12: Installation Overview

    Installation Overview The distribution amplifiers can be mounted on tabletops, in racks and under furniture. Through-desk mounting is not recommended for these products. To install these units, follow these steps: Turn off all electrical equipment. Make sure that the input sources, the distribution amplifier, and the output displays are all turned off, disconnected from their power sources, and connecting cables have been removed.

    overloading might have on overcurrent protection and supply wiring. Give appropriate consideration to the equipment nameplate ratings when addressing this concern. Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted equipment. Pay particular attention to supply connections other than direct connections to the branch circuit (such as the use of power strips).
