System Bus Connections; Initial Start-Up Procedure - Harris ZX2500 Technical Manual

Section 2 Installation
NOTE:
The RF splitter has a bracket designed for mounting to a cabinet rear rack rail
behind the amplifier chassis. The splitter can be removed from the angle bracket
and rotated as necessary to facilitate mounting.

2.12 System Bus Connections

The system bus port provides a means to connect multiple PA chassis to together for
parallel operation in transmitters at the 7.5kW level and above. All PA chassis must
have their SYSTEM INTERFACE ports interconnected for the transmitter to operate
properly. This interconnection is performed by a five-way HD15 divider board
mounted on the transmitter cabinet component panel. There are no user connections on
the system bus.

2.13 Initial Start-up Procedure

This procedure provides the steps required to turn on the ZX series transmitter for the
first time. It is recommended that installation personnel read the general description in
Section 1, the controls and operation material in Section 3, and this procedure before
starting.

WARNING: Disconnect primary power prior to servicing.
Carefully inspect transmitter for loose hardware, unconnected wires,
missing parts, debris, or other signs of damage from shipment.
If transmitter was supplied with optional rack integration, install rack in
a suitable location. Temporarily remove optional air input plenum, as
necessary, to facilitate moving transmitter rack through doorways.
(where applicable)
a. Secure rack to floor, neighboring racks, as necessary.
b. Connect rack to intake and exhaust ducts, as necessary.
If transmitter was supplied without optional rack integration, mount
amplifier chassis and exciter in EIA rack. If transmitter was shipped
with all modules in place, modules can be temporarily removed to
lighten chassis and facilitate installation.
a. Provide rear-rail and/or under-chassis support as necessary to pre-
vent chassis from warping rack rails over time.
Establish AC mains, RF output, and exciter connections to transmitter.
See discussion of these connections earlier in this manual section.
