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 slide-rails included in the installation material for your system. Refer to
Figure 2 and the manufacturers instructions, included with the drawer slide-rails, for the
cabinet mounting instructions of the drawer slide-rails.
Install the left drawer slid-rail 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-rail 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-rail on the right side of the cabinet (as viewed from the rear)
making sure that it is aligned with the drawer slide-rail on the left side. Secure the slide-
rail 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 slide-rails in place, slide the drawer or drawers into the cabinet.

AC Input Connections
Single Amplifier Drawer Systems
The CU0TD/RD-1, CU0TD/RD-2 and CU0TD/RD-3 single drawer systems will operate with
an input voltage of 85-253VAC. The CU0TD/RD-4 single drawer systems operate on 185-
253VAC. The customer should provide a single point disconnect for the main AC input
connection to the transmitter. Check that the AC switch, located on the rear of the drawer
above the AC power jack, is OFF. Connect the AC power cord supplied with the drawer
from J6 on the rear of the drawer to the AC source. If your system has the optional ASI
to S310 Converter, check that it is connected to the AC source.
