Measure
the
outside
width
of
the
main
frame
channel
of
your
RV.
Lay
out
the
two
(2)
Power
Twin
leg
assemblies
(see
figure
in
this
section
below)
and
adjust
the
inside
distance
between
the
two
(2)
mounting
plates
to
the
same
as
the
outside
dimension
of
your
RV
frame.
Take
the
connecting
bracket
(#34)
and
position
it
over
the
two
(2)
side
by
side
main
channels
(#1)
and
bolt
by
using
eight
(8)
M8
‐
1.25x25mm
hex
head
bolts
(#37)
with
the
M8
flat
washers
(#36)
and
M8x1.25
NYLOCK
nuts
(#35).
Do
not
tighten
at
this
time.
❹
Attach
the
Power
Twin
assembly
to
the
frame
by
using
the
holes
provided
in
the
mounting
plate
(#2)
and
(6
each
side)
⅜
”
***hex
head
bolts
and
nuts
or
⅜
”
self
drilling
***hex
head
screws.
DO
NOT
use
any
fasteners
smaller
than
¼”
diameter.
❺
To
finish
assembly,
go
back
and
tighten
the
eight
(8)
bolts
and
nuts
at
the
connecting
bracket
(#34).
❻
Next
step
is
to
wire
the
switches
to
our
motor
assemblies
and
connect
to
the
12
‐
volt
power
supply.
NOTE:
In
some
installations,
to
achieve
the
maximum
stabilization
you
require,
it
may
be
necessary
to
support
the
connecting
bracket
to
the
frame
of
your
RV.
We
do
not
supply
the
brackets
as
there
are
many
different
configurations
of
cross
members
and
in
most
installations
it
is
not
necessary.

MOTOR
INSTALLATION
❶
Attach
each
of
the
motor
and
gear
box
assemblies
(#22)
to
the
Power
Twin
II
with
the
four
(4)
M6
‐
1.0x110mm
hex
bolts
(#24)
making
sure
the
gasket
(#27)
is
between
the
motor
cover
and
the
gear
box.
NOTE:
Make
sure
that
the
wires
come
out
of
the
bottom
side
of
the
motor
cover
(towards
the
ground
when
installed).
REPEAT
this
step
for
the
second
motor
and
gear
box
assembly.
❷
The
switches
may
be
mounted
at
any
desired
location,
but
a
preferred
location
would
be
in
a
protected
environment,
such
as
a
storage
compartment
or
switch
box
near
the
jacks.
THE
GOAL:
To
be
child
‐
proof
as
well
as
weather
‐
proof.
❸
CAUTION:
To
avoid
short
circuits,
remove
the
fuses
(#28)
from
the
fuse
holders
(#29)
until
the
wiring
is
complete.
Use
10
gauge
(supplied)
wires
for
the
install.
Using
a
smaller
gauge
wire
will
void
the
warranty.
Join
all
wire
connections
with
solder
connections
or
crimp
type
connection.
DO
NOT
use
wire
nuts
as
they
tend
to
loosen
and
fall
off.
❹
Connect
the
GREEN
wire
to
the
negative
terminal
of
the
battery,
or
securely
ground
it
to
the
frame
(a
clean
and
paint
‐
free
area).
❺
Connect
the
WHITE
wire
to
the
positive
terminal
of
the
battery,
or
the
nearest
positive
terminal
block.
Make
sure
to
install
the
fuse
holders
(#29)
on
this
WHITE
wire,
one
on
each
switch.
If
running
more
than
15
feet
of
wire
to
access
the
battery,
use
a
larger
wire,
such
as
6
gauge
wire.
This
will
assure
maximum
performance.
Voltage
drop
is
a
concern
on
long
spans.
❻
Connect
the
BLACK
wire
from
the
motor
to
the
BLACK
wire
of
the
switch.
Connect
the
RED
wire
from
the
motor
to
the
RED
wire
of
the
switch
(on
each
motor).
