Section 2 Preparation for Use and Installation
2.3.4 Cabinet Mounting
If the user is supplying the 19-inch
mounting cabinet, install the transmitter in
the cabinet, ensuring the drawer slides on
each side of the transmitter are mated/
locked together.If the deluxe cabinet,
short cabinet or IP66 cabinet option was
purchased, the transmitter is shipped from
Nautel inside the cabinet.
If the transmitter was shipped in a deluxe
cabinet or short cabinet, temporarily
remove both of the cabinet’s side panels
(two screws at the top of the cabinet and,
for the short cabinet, two additional
screws on the lower, front and rear) and
then remove four shipping screws (M8,
two on each side) from the transmitter
(see Figure MD-1B or MD-1D).
2.3.5 Determining Control/
Monitoring Requirements
There are several remote control and
monitoring options to consider before
installing external wiring. The pre-
installation information in paragraph 2.2
identifies the remote controls and alarm/
status outputs available. It is assumed the
user has already reviewed this information
and has determined which to use. It is
also assumed the options available for the
control inputs and the monitoring outputs
have been reviewed and the user has
determined which options are required to
interface with the external equipment.
2.3.6 Installing External Control/
Monitor Wiring
Connect the wiring from the remote
control/monitoring devices to the remote
interface PWB (A3) as follows:
NOTE
Remote control and monitor wiring
terminate on the remote interface PWB
(A3), which is accessible from the back of
the front panel (see Figure 2-2). The
connectors, included in the ancillary kit,
are solder-cup type and the terminal
blocks accept wires sizes (AWG) # 14
through # 24.
A cable routing channel (see Figure 2-2)
allows wiring to pass between the front
and back of the transmitter. Remote
control/monitor wiring should enter and
exit at the back of the transmitter.

(a) Route wires from the back of the
transmitter through the cable routing
channel hole to the remote interface
PWB (A3) on the back of the front
panel. Using Tables 2-3 through 2-5
(note the applicable serial interface
options), determine the specific
destination of each wire.
(b) Pass all control/monitor wires,
including their shields, through a
ferrite toroid supplied in the ancillary
kit. If practical, pass the wires through
each toroid a minimum of two times
(two turns).
