NX10 INSTALLATION MANUAL PREPARING FOR INSTALLATION
VERSION 2.0 2016-05-06 PAGE 2.1.1
SECTION 2.1: PREPARING FOR INSTALLATION
Before installing your NX10 transmitter, perform the following steps:
1. Ensure that you have performed the pre-installation tasks described in the
NX10 Pre-Installation Manual .
2. Make sure that you received all the components. (Check your packing list.)
3. Inspect all crates and packages for damage. Inspect 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 remaining outer plywood shell by unscrewing the outer wood panels from the
pallet under the transmitter.

NX10 INSTALLATION MANUAL UNPACKING AND POSITIONING
VERSION 2.0 2016-05-06 PAGE 2.2.1
SECTION 2.2: UNPACKING AND POSITIONING
To install an NX10 transmitter, perform the following tasks:
NOTE: The NX10 is housed in a single cabinet, which includes the power transformer. The cabinet is
designed for installation with or without a forklift. Both methods of installation are described in this
section. Crated and uncrated cabinet weights are shown in Table 2.2.1.
Table 2.2.1: NX10 Weight
1. Ensure the NX10’s outer plywood shell has been removed.
2. Lift the transmitter off the pallet, using a forklift or sufficient manpower. If you are using a forklift,
lift the NX10 from the front or rear of the cabinet (see Figure 2.2.1 on page 2.2.2).
NOTE: If you are using a forklift, ensure the two forks will fit together in the space provided.
3. Move the NX10 into its final position, using one of the following methods:
using a forklift, if available, and go to Step 5.
using a pallet jack, and go to Step 5.
NOTE: If you are using a pallet jack, ensure that one fork of the pallet jack is centered under
the transmitter cabinet and that an additional person is available to assist with stabilizing the
transmitter while it is being lifted and moved.
installing casters to roll the transmitter, as detailed in Step 4.
WARNING! DO NOT ATTEMPT TO MOVE THE TRANSMITTER CABINET
UNLESS SUFFICIENT MANPOWER OR MECHANICAL ASSISTANCE IS
AVAILABLE TO MOVE IT INTO POSITION WITHOUT DAMAGING THE CABINET
OR CAUSING INJURY TO PERSONNEL.
CAUTION! THE NX10 CONTAINS ADJUSTABLE FEET THAT ALLOW LEVELING
OF THE CABINET IN ITS FINAL POSITION. ENSURE THE LEVELING FEET ARE
FULLY RETRACTED (UP) BEFORE MOVING THE NX10. FAILURE TO DO SO
MAY CAUSE DAMAGE TO THE LEVELING FEET AND ATTACHED
METALWORK.
CRATED WEIGHT UNCRATED WEIGHT
371 kg (817 lbs) 315 kg (695 lbs)
NOTE: Weights assume standard method of shipping, which includes power transformer in cabinet.

4. If you are using the provided casters to roll the NX10 into position, perform the following (see
Figure 2.2.2 on page 2.2.4):
Open the front and rear doors of the NX10. Remove the four hole plugs from each bottom
corner to expose the top of the threaded leveling feet.
Use the 3/16-inch hex bit socket (Nautel Part # HY120, provided in the ancillary kit) and a 3/8-
inch drive ratchet (user provided) to extend each leveling foot to the transmitter room floor.
Continue to extend the levelers so that the NX10 is approximately 1” (25 mm) above the floor.
Obtain the four casters (Nautel Part # HAW73), eight spacers (Nautel Part # 212-8166),
16 M8 x 25-mm hex bolts (Nautel Part # HMBH02) and M8 nuts and washers from the
ancillary kit.
Use two spacers, four M8 bolts, nuts and washers to secure each caster to the bottom of the
NX10 (see Figure 2.2.2 on page 2.2.4).
NOTE: It may not be possible to install all four (4) bolts in the front casters. Install at least two
(2) bolts, in opposite corners, taking care not to damage the power transformer.
Use the 3/16-inch hex bit socket to retract the levelers until the casters rest on the floor.
Continue to retract the levelers a further 1” (25 mm).
Roll the NX10 into its final position. Extend the levelers to elevate the casters off the floor.
Remove the casters and associated hardware. Store them for future use.
Adjust the levelers until the NX10 rests on the floor.
5. If you are not anchoring your transmitter, adjust the levelers until the NX10 is level. 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 the four pre-drilled mounting
holes in the floor (see Figure 1.2.1 of the NX10 Pre-Installation Manual for pre-drilled hole
locations) and install four anchoring bolts (user-provided), with square washers, in the holes
provided in the bottom of the transmitter cabinet (see Figure 2.2.3 on page 2.2.5).
NOTE: The maximum bolt length that can be used for seismic anchoring is dependent on the height
of the cabinet opening above the anchor holes [3.5 inches (9 cm)] and the tool you are using to
anchor the bolts. If the bolts are too long, try jacking up the transmitter cabinet (by adjusting the
levelers), then installing the bolts while slowly dropping the height of the transmitter until it rests
on the floor.
6. Obtain the front dress panel (Nautel Part # 212-8122-01) and rear dress panel (Nautel Part #
212-8122-02) from the ancillary kit. Install the panels as shown in Figure 2.2.4 on page 2.2.5.

7. If you are using a closed air cooling configuration (see the NX10 Pre-Installation Manual for
details):
Obtain the cover plate (Nautel Part # 212-5052) that was packed with the NX10 ancillaries.
Loosen the four (4) quarter-turn fasteners that secure the filter bracket to the rear door and
remove the filter bracket (see Figure 2.2.5 on page 2.2.7).
Install the cover plate in its place and tighten its quarter-turn fasteners.
Remove the cover plate from the top of the NX10 (see Figure 2.2.5 on page 2.2.7) and attach
the user-provided air intake duct.
8. Verify that the ac power cable from the ac power disconnect switch is long enough to reach
through the entry point at the top or bottom of the NX10, to the transformer’s primary terminals at
the bottom of the NX10.
9. Install the RF output connector as follows (see Figure 2.2.6 on page 2.2.8 or Figure 2.2.7 on page
2.2.9):
NOTE: The RF output connector for an NX10 can be configured for an 1-5/8 inch or 7/8 inch EIA
connector. An output connector kit for the predetermined connector is provided with the ancillaries. The
user must provide the appropriate inner male (bullet) connector and field flange connector to complete
the RF output connector.
Obtain the appropriate output connector kit (Nautel Part # 212-6200 for 1-5/8 inch or Nautel
Part # 212-6200-01 for 7/8 inch), which was packed with the ancillary crate. Install the output
cup, spacer plate and stud plate as shown in Figure 2.2.6 on page 2.2.8 (1-5/8 inch EIA) or
Figure 2.2.7 on page 2.2.9 (7/8 inch EIA), using hardware provided in the kit.
Install the user-provided inner male (bullet) connector in the RF output cup and install the
user-provided field flange on top of the stud plate. Secure using provided hardware. RF feed
cable installation is completed later in this manual.
10. Verify that the RF feed cable reaches the RF output connector on the top of the NX10.
11. Remove the rear door’s securing screws and open the rear door. Locate the arc detector assembly
(A24) (see Figure 2.2.8 on page 2.2.10) and remove the protective packing material that was added
to prevent shipping damage. Close and secure the rear door.
