Setting up the transmitters
The SR 3254 and SR 3256 transmitters heat up during
operation.
y Ventilation in fixed installations
Ensure sufficient ventilation, especially when the transmitters
are mounted into a desk or chassis. Provide for a duct of
sufficient size to ensure a free air flow between the trans-
mitters.
y Sufficient ventilation in a rack
When operating several transmitters in a rack, ensure
sufficient ventilation or cooling. We recommend not stacking
more than two transmitter directly one above the other, and
then providing for a duct of sufficient size to ensure a free air
flow between the transmitters.
