XR12 Transmitter Pre-installation Manual Physical requirements

Clearances
Required minimum clearances are 1.3 m (4.0 feet) at the front of the transmitter, and 2.0 m (6.0 feet)
at the rear of the transmitter. (The clearance at the rear of the transmitter is required to allow
installation of the power transformer. Less clearance may be acceptable if special arrangements are
made to install the transformer.) No clearance is required on either side of the transmitter.
Check the clearance to ensure that you will be able to open all doors and access panels. The front
control panel is hinged on the left (when looking at the front of the transmitter).
Also consider access to the rear of the transmitter during transformer installation and servicing, and
access to the front of the transmitter during power module replacement. You must allow space to
open the front panel and slide out any of the power modules. These modules slide straight in and out
of the shelf unit in the front of the transmitter.
Internal fans pull cooling air through air filters in the upper rear panel. The cooling air exhausts as a
low velocity stream through openings on top of the transmitter.
