Note
All the information appearing in this section is presented for RM1200 used with

For RM125/RM125R installation and operation instructions, refer to the
“RM125/RM125R Owner’s Guide”, Publication 6888882V02.
If you are using another vendor’s equipment, refer to its installation and
operation manual.
Refer to Figure 5 for a typical RM1200 interconnection diagram (this figure shows a system using the
RM125/RM125R as exciter).
1. Identify the installation position of each equipment unit in the rack.
2. Install each equipment unit in the prescribed installation position, fastening it by means of
screws to the rack rails or to the drawer front.
3. Connect grounding straps from each grounding screw (located on the rear panels of the
various units), to the prescribed cabinet’s grounding bar.
4. Set all the power switches on all the equipment front panels to OFF (down position).
Caution
The 1 kW PA unit does not have a power switch, and therefore it will start
operating as soon as the RM125/RM125R is turned on, provided that the
PS unit is already turned on.
5. Connect cables to the RM125/RM125R unit as explained in its Owner’s Guide, including the
relevant DC power connections. The only difference is that the RM125/RM125R RF OUT
connector must be connected to the RF IN connector of the 1 kW amplifier.
6. Connect the control cable between the RM125/RM125R AMP-CONT connector and the 1 kW
amplifier EXCITER CONTROL connector.
7. Connect the antenna feed cable to the RF OUT connector of the 1 kW amplifier.
8. Connect the DC power cable between the 1 kW amp48VDC connector and the four
DC OUTPUT terminals of the PS unit. Pay attention to correct connection of the two pairs of
leads to the DC OUTPUT terminals, with respect to polarity and OUT pair.
9. Connect the three leads of the PS unit AC power cable to the AC INPUT terminal strip, in
accordance with the functions of each lead. After making the connections, make sure that the
protective cover of the terminal strip is properly installed.
