SECTION 2.2: UNPACKING AND POSITIONING
To install an NV20LT/NV15LT 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: NV20LT/NV15LT 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.
