14-Way Combiner Assembly Replacement
The
following
instructions
explain
how
to
replace
the
14
‐
Way
Combiner
Assembly
in
the
rear
of
a
10
kW
power
block.
These
instructions
can
also
be
followed
to
remove
the
combiner
for
easier
access
to
the
Power
Supply
Interface
PWA
that
is
mounted
behind
it.
Prior
to
removal
the
transmission
line
connected
to
the
RF
output
will
need
to
be
removed.
In
higher
power
FAX
transmitters,
20
kW
and
above,
the
combiners
will
need
to
be
removed
as
well.
See
the
procedures
in
this
section
of
the
manual
on
how
to
remove
them.
STEP 1
Remove
all
power
to
the
transmitter.
STEP 2
Open
the
back
door
to
the
power
block
that
the
splitter
is
to
be
replaced
in.
Remove
the
14
coaxes
that
are
attached
from
the
splitter
to
the
14
‐
Way
combiner.
These
are
the
reject
load
connections
which
are
not
critical
and
can
be
reconnected
in
any
location.
STEP 3
Remove
the
hose
clamp
from
the
RF
output
connector.
Then
remove
all
of
the
hardware
at
the
arrows
shown
in
Figure

This
will
allow
the
panel
to
be
tilted
up
and
out
of
the
way.
