Power Supply
The Power Supply of the receiver is housed in the
Power Module. The Power Supply requires 16.5 VAC
as input, and has a 13.4 VDC stabilized power output
with fuse and a 13.8 VDC stabilized battery charging
output with fuse.
Using a 100VA 16.5 VAC transformer connect AC
power to the Power Module. Connect the battery
cables to the battery outputs. Use a 7 Ah or 15 Ah
backup battery.
Ensure that all connections have been made
correctly.

Removing and Installing Modules
The receiver does not have to be powered down
while components of the system are removed or
installed.
CPM Module
Remove the 4 retaining screws on the front panel of
the module. Carefully pull the module out of the
subrack housing.
Installation is the reversal of removal. Push the
module carefully and firmly back to its place, then
mount the retaining screws. After plugging in, the
CPM Unit will make a cold start.
Dual Line Card Module
Remove the 4 retaining screws on the front panel of
the module. Carefully pull the module out of the
subrack housing.
Installation is the reversal of removal.
Install Additional Line Card Modules
To install new Line Card Modules to the system an
extension subrack with Line Card Module backplane
is required. The backplane is shipped with power and
communications bus extension cables.
To install the extension subrack with the LCM
backplane do the following:
Install the LCM backplane to the extension
subrack
Remove the top cover of the desktop housing
Mount the base subrack and the extension
subrack together with subrack extender brackets
Mount the top cover onto the top of the
assembly.
Connect the power cable to the receivers power
bus, but do not connect the communications bus
cable yet.
Push the new LCM module into its place, the
module will power-up.
Assign Line Card Numbers to the two line cards
in the module as described in chapter 5. Be
careful not to assign the same Line Card Number
for two line cards because that can cause system
malfunction.
Now connect the communications bus to the new
Line Card Module on the backplane with the
supplied cable.
The CPM will identify the new Line Cards,
receive and display their events.
Note, that when installing new modules, always assign Line
Card numbers to the Line Cards before connecting the new
module to the communications bus, otherwise the CPM
might fail to recognize the new Line Cards.
