Caution
Before installing equipment units on slides, make sure you are familiar
with the procedures needed to install slides in the rack/cabinet, and to
safely install heavy equipment on the slides.
Installation Procedure
Refer to Figure 13 for a typical system interconnection diagram.
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 the
Installation Procedure – Basic
section, starting on page 14, 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.
If your installation includes the PPS, use the procedure explained in the
section, starting on page 16.
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.
10. Connect the other end of the AC power cable of the PS unit to the prescribed outlet on the
power distribution box of the cabinet.
