Also needed for FCC compliance operation is an ATSC filter on the broadcast channel that
connects to the output of the CU0TD/RD thru CU4TD/RD systems. Space must be
provided for the ATSC filter, and in some systems, for the circulator, splitter, combiner,
reject load, and low pass filter whose dimensions will vary depending on manufacturer and
channel. Refer to the vendor supplied information included with your ATSC filter and low
pass filter for specific dimensions. Make sure that the space provided for the CX Series
equipment is sufficient and includes the circulator, splitters, combiners, reject load and
external filters. Check that any additional equipment, which is included in the system that
extends above or to the side of the mounting rack, has sufficient clearance space. Refer
to the custom racking plan for the system, if prepared, for detailed information.
Drawer Slide Installation
If the system is pre-mounted in a cabinet skip this section. Locate the drawer slides
included in the installation material for your system. See Figure 2 and the manufacturers
instructions, included with the drawer slides, for the cabinet mounting instructions of the
drawer slides. Install the left drawer slide into the left side of the cabinet (as viewed from
the rear). Allow 3 RU, 5.25” (13.3cm) of space between the drawers for a CU0TD/RD-1,
CU0TD/RD-2, CU0TD/RD-3, CU0TD/RD-4 & CU0TD/RD-5 systems. In high power systems,
allow a space of 3 RU, 5.25” (13.3cm) for the driver drawer and 6 RU, 10.5” (26.7cm) for
each of the amplifier drawers. Space must also be provided for the splitter, combiner,
ATSC filter and low pass filter, if present, whose dimensions will vary depending on the
manufacturer and the output channel. Secure the left drawer slide by connecting it to the
front and rear mounting bars using No. 10 screws and the bar nuts that have been
provided. Install the drawer slide on the right side of the cabinet (as viewed from the rear)
making sure that it is aligned with the drawer slide on the left side. Secure the slide by
connecting it to the front and rear mounting bars using No. 10 screws and the bar nuts that
have been provided. Repeat this process for any other drawers if purchased. With both
slides in place, slide the drawer or drawers into the cabinet.
