Installation & Initial Turn-On
2.5.5.2 Single Phase Power Supply Connections
First, remove the front cover panel from the power supply compartment at the
bottom of the transmitter. The power supply connection cables are either tied up in
the power supply compartment (in the bottom of the transmitter) or tied up with the
power transformers. The power supply should be rolled into position in front of the
transmitter. Do not roll it all the way in. The following cables will need to be
connected:
a. There are two ribbon cables and one power connector hanging on the right
side of the power supply compartment inside the transmitter. The ribbon
cables connect to J4 on the Rectifier Boards. The longer ribbon cable, W12
connects to the Rectifier Board on PS2 (nearest the back of the transmitter)
and should be connected first. Be sure to route this cable so it does not touch
the resistor standing up on top of the Rectifier heatsink. See Figure 2-3.
b. The shorter blue ribbon cable, W21 connects to the front Rectifier Board on
PS1. The power cable, W11 (the gray cable with the orange connector) con-
nects to J6, on the Rectifier Board nearest the front of the transmitter.
c. The cable labeled A1P2 (gray and yellow multi-conductor cable with gray
connector) plugs into its mating connector on the left wall of the power sup-
ply compartment. Roll the power supply all the way into the cabinet.
d. Wires 80 and 81 (large orange cables tied up with the transformers) connect to
the feed-thru terminals at the top of the power supply compartment. See Fig-
ure 2-4. The cables are dressed such that the shorter cable, 81 connects to the
left hand terminal and the longer cable, 80 connects to the right hand terminal.
