Disconnecting the Ground

UL Rack-Mounting Guidelines

The following Underwriters Laboratories (UL) requirements pertain to the installation of the unit into a rack.

•Elevated operating ambient temperature — If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consider installing the equipment in an environment compatible with the maximum ambient temperature (TMA = +122 °F, +50 °C) specified by Extron.

•Reduced air flow — Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.

•Mechanical loading — Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.

•Circuit overloading — Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.

•Reliable earthing (grounding) — Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (such as use of power strips).

If you cannot resolve a ground potential difference between the transmitter and receiver installation sites (as suggested by a missing or unstable picture), remove the ground connection between the units as follows:

NOTE: Once you have removed the ground jumpers, the DTP DVI 230 cannot extend analog audio and one unit cannot remotely power the other. No analog audio is output and each unit requires a local power supply.

1.Disconnect any cables and remove the transmitter and receiver from any rack or other installation option.

2.Remove and retain the screws securing the covers to the transmitter and receiver. Slide the covers forward slightly and lift them off both units (see figure 9).

•Transmitter — Six screws, two on each side and two on top

•Receiver — Eight screws, three on each side and two on top
