 Use a chassis punch tool (e.g., Greenlee, etc.) to punch the desired size hole in the program
input entry plate. Make sure the program input cables will pass safely through the hole. If
necessary, you can remove the plate completely to gain access to a 2.5-inch diameter hole.
 Re-install the program input entry plate on top of the transmitter using four M4 screws.
5. Route the program input cables through the entry hole. Once the cables are inside the transmitter,
Nautel recommends you route cables to the controller and optional exciter B through the built-in
conduit (channel) on the right-hand side of the cabinet (as viewed from the rear; see channel entry
and exit points on
Figure 2.7.2 on page 2.7.3 ; conduit dimensions are 1-11/16 inches x 3/4 inches).
If possible, install exciter mating connectors after passing cables through the conduit. Wear strip is
factory installed at the channel entry and exit points to protect the cable insulation. If your
program wiring will not pass through the channel, route it along the outside of the channel using
the provided tyrap anchor holes and secure the cables using Nautel Part # HAC15 snap-mount
tyraps (for 0.25” holes), provided in the ancillary kit.
NOTE
: When routing program cables through the built-in conduit, consider the possibility that remote
control/monitor wires and a LAN cable may also pass through the conduit (see Section 2.8, “Installing
Control/Monitor Wiring” on page 2.8.1 ).
6. With the program input cables near the rear of the controller and optional exciter, cut each wire to
the required length, and install connectors, as necessary.
7. Remove plastic cap-plugs from the connectors on the controller and exciter, if applicable.
8. Connect the appropriate program input cable(s) to the controller and optional exciter connector(s)
described in Section 1.7 of the NV20LT/NV15LT Pre-installation Manual.
