VERSION 5.0 2021-03-01 PAGE 2.1.1
SECTION 2.1: PREPARING FOR INSTALLATION
Before installing your NV10LT/NV7.5LT transmitter, perform the following steps:
1. Ensure that you have performed the pre-installation tasks described in the
NV10LT/NV7.5LT Pre-installation Manual.
2. Make sure that you received all the components. Check your packing list.
3. Inspect all crates and packages for damage. Monitor the tip and drop indicators attached to the
crates to determine if a crate has been tipped over or has been subjected to excessive shock (see
Figure 2.1.1).
Figure 2.1.1: Tip and drop indicators
4. Report any damage immediately to your Nautel sales representative and the carrier.
5. Move the crates as close as possible to the transmitter’s planned location.
6. Unpack the crates in accordance with the instructions provided on the outside of the crates.
For each crate, remove the panel labelled open this side. The panel is attached using Phillips
head screws.
Remove any visible packing material, including braces, from the crate's interior.
Remove the lag bolts on the bottom edge of the remaining three sides, leaving only the
transmitter and its support pallet.

7. Review any assembly notes or instructions contained inside the transmitter crates. (For sites
requiring custom configurations, the instructions provided with the transmitter replace the
instructions provided here.)
8. Assemble your parts and tools. For a list of required tools, see “Parts and Tools” on page 2.10.1.
9. When you are ready to install the NV10LT/NV7.5LT transmitter, follow the steps shown in
Figure 2.1.2.

NV10LT/NV7.5LT INSTALLATION MANUAL UNPACKING AND POSITIONING
VERSION 5.0 2021-03-01 PAGE 2.2.1
SECTION 2.2: UNPACKING AND POSITIONING
To install an NV10LT/NV7.5LT transmitter, perform the following tasks:
1. Lift and slide the transmitter cabinet off the base of its crate. Crated and uncrated cabinet weights
are shown in Table 2.2.1.
Table 2.2.1: NV10LT/NV7.5LT Cabinet Weights
2. Using necessary mechanical assistance (forklift, etc.), position the cabinet in its final location. If
the transmitter needs to pass through a doorway that is less than 31.0 in. (78.8 cm) wide, you
must remove the transmitter’s rear filter panel (secured with 1/4 turn fasteners). You can also
remove the front hinged UI panel to reduce the transmitter depth below 30 in. (76.2 cm).
3. Obtain the operating system (OS) password document which is attached to the Exciter handle,
located inside the lower front panel. Store in a safe place for future reference.
4. Remove the transmitter’s rear panels to allow access to customer input wiring. This may have
already been done in Step 2. See Figure 2.2.1 on page 2.2.3 to see access panels.If you are
anchoring your transmitter against seismic activity, obtain four 2-1/4 inch square washers (Nautel
Part # HPS30) from the ancillary kit. Position the transmitter over four pre-drilled mounting holes
and install four anchoring bolts (user-provided), with square washers, in the holes provided in the
bottom of the transmitter cabinet (see Figure 2.2.2 on page 2.2.4). It is possible to drill through the
hole plugs in the bottom of the transmitter, without removing them.
5. As desired, remove the M8 shipping screws in the back of each RF power module (see Figure 2.2.3
on page 2.2.5). Nautel recommends you remove these screws, unless your site experiences seismic
activity.
WARNING! DO NOT ATTEMPT TO MOVE THE TRANSMITTER UNLESS
SUFFICIENT MANPOWER OR MECHANICAL ASSISTANCE IS AVAILABLE TO
MOVE IT INTO POSITION WITHOUT DAMAGING THE CABINET OR CAUSING
INJURY TO PERSONNEL.

6. Install the RF output connector, which was partially disassembled for shipment, as follows (see
Figure 2.2.4 on page 2.2.6 through Figure 2.2.6 on page 2.2.8):
NOTE: The RF output connector was factory configured prior to shipping for the desired EIA connector
(1-5/8 inch, 3-1/8 inch or 7/8 inch).
Remove the output cover packing plate from the RF output connector on top of the
transmitter. The packing plate - along with two spacer plates - is secured using four M6
screws. Remove only the packing plate, leave the spacer plates in place and retain the screws.
Obtain the Output Stud Plate, which was packaged with the ancillaries. If unable to locate the
output stud plate in the ancillaries, it may have been tyrapped to rear of transmitter due to
space restrictions. Using the M6 screws retained above, install the output stud plate on top of
the spacer plates. Firmly tighten M6 hardware. Note that the output stud plate’s studs contain
the necessary securing hardware (nuts, flat washers and split washers) to connect the RF
output to a dummy load or the antenna system in Section 2.9, “Commissioning”.
NOTE:For 7/8 inch EIA connectors (see Figure 2.2.5 on page 2.2.7), note that the 7/8 inch adapter
(Nautel part number JS59) is found in the ancillary kit.
7. Verify that the RF feed cable reaches the RF output connector on the top of the cabinet. The RF
feed cable will be connected in Section 2.6, “Installing the RF Feed Cable”.
8. Proceed to Section 2.3, “Installing Options”to configure your transmitter for any options that were
purchased.
9. Do not re-install the rear panels at this time.

VERSION 5.0 2021-03-01 PAGE 2.3.1
SECTION 2.3: INSTALLING OPTIONS
The NV10LT/NV7.5LT transmitter is factory configured and shipped to operate with the customer’s
desired ac power source voltage and RF output connector size. There are options available for various
other features, including dual exciter, UPS interface, redundant LVPS, and remote interfacing. These
options may be installed in one of two ways:
You install and configure options at your site, using kits and instructions provided by Nautel.
Each option has a separate kit.
Pre-arrange for Nautel to install and configure options at the factory prior to shipping.
Table 2.3.1 shows the standard (default) configuration of the NV10LT/NV7.5LT, as well as available
options. Each option references a schedule of installation and how to install the option. Review the
options to determine which, if any, apply to your installation.
If you did not purchase any options for your NV10LT/NV7.5LT and intend to operate with the standard
(default) configuration, proceed to Section 2.4, “Connecting to Station Reference Ground”.
NOTE: When an option is installed (UPS interface, dual exciter, etc.), the extra parts removed (e.g.,
blank exciter panel, AC LED cover) from the original configuration are placed in the Ancillary kit.

Upgrading to Dual Exciter
The NV10LT/NV7.5LT is factory configured with a single exciter - part of the controller (A4). You can
upgrade your transmitter with a second exciter (exciter B). which provides additional redundancy.
1. Turn off (disable or lock out, as applicable) the main ac power for the transmitter.
2. Obtain “QG12004* - NVLT Dual Exciter Upgrade Quick Guide” (see Figure 2.3.1) that was provided
with the Dual Exciter Upgrade Kit and complete its outlined procedure.
Figure 2.3.1: Dual Exciter Upgrade Quick Guide (QG12004*)
3. If you are performing this upgrade in conjunction with the NV10LT/NV7.5LT’s initial installation,
leave the front and rear panels off to allow further installation. If you are performing this upgrade
after initial installation has already been completed, re-install the front and rear panels.
