Disconnecting the Ground

If you cannot resolve a ground potential difference between the transmitter and receiver
installation sites, you need to remove the ground connection between the units as follows:
NOTE: Once you have removed the ground jumpers, the DTP DVI 330 cannot extend

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).
analog audio and one unit cannot remotely power the other. No analog audio is
output and each unit requires a local power supply.
Disconnect any cables and remove the transmitter and receiver from any rack or other
installation option.
Remove and retain the screws securing the covers to the transmitter and receiver. Lift
the covers off both units.
• Transmitter — Six screws, two on each side and two on top (see figure 12).
Receiver — Eight screws, three on each side and two on top (see figure 12).
