2.1.4.3 Reconnecting Cables To Modules
The connections are shown on the Transmitter Interconnect Wiring Diagram in schematic form (see figure
5.1). Cables are secured to cable retractors and are ready to be connected to modules except for the
following large coax cables:
a. PA Module RF output coax cables (qty.4) are connected between the PA modules and the Combiner
module.
b. Combiner output coax is connected between the Combiner and the Antenna connector.
Connection to the individual modules is described below.
2.1.4.3.1 Power Supply Module Connections
Connections to the Power Supply module rear panel terminal block are shown below:
L3 L2 L1
The AC LINE Input is connected as follows: L1: Line 1 (black)
L2: Line 2 (red)
L3: Line 3 (blue)
: Ground (green)
The System Controller and Exciter module AC Line inputs connect to J2 of the Power Supply module
through a splitter cable.
The 50V DC NEG (-) connections from the four PA modules are attached to the Power Supply output
terminal bus bar with a 3/8” bolt. The terminal lug must directly contact the bus bar (no washers between the
lug and the bus bar). Tighten the bolt securely.
The 50V DC POS (+) connectors connect to J3A and J3B.
The supply control cable 9 Pin DSUB plug connects to Power Supply connector J4.
