UNPACKING & MOUNTING

2.1

Remove the Transmitter cabinet from its shipping container , open the front panel, and remove any 
shipping  material that may be included. Make a careful inspection looking for obvious shipping 
damage. Remove any foreign material that may have shaken loose. 

2.2

Some PC boards are shipped in separate boxes. Individually unpack and inspect them for any obvious 
shipping damage. Check the connectors for any bent pins. Be sure to do this before attempting to 
plug any of the PCB's in.

2.3

Assuming the transmitter is not to be pre-tested in a lab facility, physically mount the Cabinet to its 
permanent structure. See drawing SDE10018, Page 5,

 

 for mounting hole dimensions.

PLUG INS

3.1

See the  System installation drawings,  SDF31002 , Pages 9 and 10,  for additional information 
pertaining to the following steps. 

3.2

Remove the front panel exposing the Controller/ Monitor, Transmitter 1and User Sections

3.3

Remove the Controller Monitor cover panel and set it aside

3.4

Verify that the Monitor/Controller, Analog I/O and Digital I/O are installed and well seated in the 
correct slots according to the drawing.

3.5

Unpack the smaller 3U sized Low Voltage Power supply PCB (SLP10017) and examine it closely for 
any damage.

3.6

Check JP1 and JP2 on this PCB and verify they set correctly for the input voltage being used.

3.7

 Refer to Drawing  SDF31002, Page 10,  and insert the LVPS PCB (SLP10017) into the left-most 
slot. The board insertion must be exactly as shown in the drawing or serious damage may occur. 

3.8

Remove the Transmitter 1 cover panel

3.9

Unpack the Transmitter 1 PCBs and examine them closely for any damage

3.10 Install the RF Amplifier PCB (SLP10001) in slot #2 or right  next to the already installed Filter /

Bridge PCB (SLP10002) . See Drawing
