ANDERSEN Stainless Steel Winches®
Your Andersen winch is made with the care and craftsmanship that
come from more than sixty years of experience. Andersen winches
are built to last, to retain their exceptional nish and to deliver
season after season of reliable performance and sailing pleasure to
their owners through the years.
Compact Motor™ functionality
The Andersen Compact Motor™ is a brushless DC motor, carefully
matched to a low prole planetary gearbox, which requires less
space for installation and draws considerably less current than
traditional motor/gearbox congurations. Simplied electrical
installation requires no external control box.
The Compact Motor™ includes a dedicated circuit breaker with
integral controller and two illuminated “intelligent” push buttons
which regulate speed and power in the low and high speed ranges
of operation, in proportion to the pressure applied.
Manual operation is possible at any time using a normal winch
handle.
Monitoring and protection
The integrated controller will cause the motor to stop without
tripping the circuit breaker if one of the following conditions is
detected:
• Maximum pulling load exceeded. The motor will cut out if
the pre-set maximum pulling load of the winch for electrical
operation is exceeded. Operation can resume within a few
seconds when the load returns below the limit.
• Overheating. The motor will cut out if the temperature of the
motor circuit reaches 60˚C (140˚F). Operation can resume when
the temperature returns to normal.
• Maximum continuous run time exceeded. The motor will cut
out after running continuously for 4 minutes and 15 seconds.
Operation can resume after releasing the push button to pause
operation for at least 30 seconds.
In these cases, the illuminated push button will ash, indicating that
the controller will reset automatically when operating conditions
return to normal.
Read All Safety Notices and Product Manuals
Do not install or operate this winch before reading and fully understanding the contents of this Safety Notice Sheet and the
Product Manual.
Stay Alert When Operating
Andersen winches are very powerful and have the potential to cause signicant damage and/or serious injury if used
improperly or without due caution and vigilance.
Operators Must be Trained
Help prevent signicant damage and/or serious injury by ensuring any person operating a winch has a thorough
understanding of its proper operation and is aware of the potential hazards involved. As a minimum, all winch operators
must read and understand this Safety Notice Sheet and the Product Manual.
Particular attention is drawn to the following points:
• Children and others not qualied to operate an electric winch must be kept at a safe distance from the winch and any
rigging or ttings that are under load.
• Long hair and/or loose clothing must be tied back to avoid being caught in the winch.
• In the event of a rope override or other fault, stop the winch and turn o power before attempting to resolve the
problem.
Avoid Accidental Operation
Always turn o power to the winch at the circuit breaker and remove winch handles when not in use to help avoid
unsupervised or unintentional operation. Failure to do so could result in signicant damage and/or serious injury.
Maintenance
Turn o power to the winch before performing any maintenance or service tasks. Failure to do so could result in signicant
damage and/or serious injury.
Lifting Operations
The winch must not be operated with the rope in the self tailer when used in any kind of lifting operation. Any lifting
operations should be conducted by two persons in order to maintain constant visual contact with the object being lifted.
Furthermore the self tailer must not be used as a cleat for a rope used to lift or suspend any object. The rope must be
secured properly by tying o, or leading to a suitable tting such as a cleat or bollard.
Failure to observe these precautions could result in serious injury
or death.

These details can be found as shown below.
Winch production year and month [YY-MM] followed by
version number are stamped on winch base between
the mounting bolt holes.
Installation Instructions
STEP 1
Determine the position of the winch and motor unit
1.1 Magnetic elds in the motor may aect compasses even
when the motor is not in use. Install the motor at least
1m (3ft) away from any compass, and always have your
compass recalibrated after installation.
1.2 The winch should be positioned with the recommended
line entry angle of 3-8° from horizontal.
1.3 Refer to the Winch Data Sheet for your winch model for
clearance/space requirements for the motor unit below deck.
You may choose to drill a small pilot hole to indicate the
position of the centre of the drive shaft, to assist with this.
1.4 Note the location of the drain port in the base of the motor.
If the mounting surface is not horizontal due to deck camber
or other factors, plan the installation such that the drain port
is situated at the lowest point in relation to the slope of the
mounting surface. The drain tube [A12] will be attached to
this port to allow any moisture from condensation to escape
and drain to the bilge.

STEP 2
Install the deck plate
2.1 Refer to the product manual for your 46 or 50ST winch.
Disassemble the winch and base cover to access the deck plate
for installation. Remove the plug in the base plate to expose the
octagonal hole where the motor drive unit will be connected.
2.2 The drilling template [A3] can be used to identify the locations on
deck for the mounting holes and deck cut-outs. The self-tailing
arm of the winch can be adjusted after installation into one of
eight dierent positions as indicated on the drilling template.
2.3 Use the drilling template as a guide for preparing the deck.
Ensure that the mounting surface is at and there is adequate
space and clearance on deck for the winch base and below
deck for the motor. With the drilling template in the desired
orientation, drill or cut the Ø70mm (2 3/4’’) hole for the motor
drive shaft housing.
2.4 Drill the Ø8.5mm holes for the M8 deck plate mounting bolts
(11/32” holes for 5/16” bolts).
2.5 Clean any wood or breglass splinters from the holes, and clean
the deck thoroughly to ensure deck sealant can adhere properly.
2.6 Apply sealant to the deck where the deck plate will be xed. For
aluminium boats use a galvanic isolating ring/gasket.
2.7 Fit the deck plate to the deck using appropriate length M8 or
5/16” countersunk head bolts, large washers or backing plate,
and locking nuts.
STEP 3
Fit the motor unit to the deck plate
Correct alignment of the motor during assembly is essential. Improper
alignment can cause excessive noise and vibration and lead to
premature wear of bearings and gears. For best results the following
steps should be carried out by two persons.
3.1 Refer to the exploded diagram and remove the circlip [2],
gearwheel [3] to expose the clamping ring [5].
3.2 Back out the locking grub screw [4] and use the pin spanner
[A6] to remove the clamping ring from the top of the drive shaft
housing, taking care that the O-ring underneath remains in place.
3.3 Screw the M6 eye bolt [A5] into the threaded hole in the top of
the drive shaft. Attach a strong rope or use a lifting device to raise
the motor unit into position so that the drive shaft protrudes
through the large octagonal hole in the deck plate.
3.4 Align the motor unit so that the protruding octagonal detail at the
top of the drive shaft housing mates snugly with the octagonal
recess in the deck plate, for a uniform ush t.
3.5 Fit and securely tighten the clamping ring using the pin spanner,
then insert and tighten the locking grub screw. Watertight
assembly is ensured by the O-ring under the deck plate; no
additional sealant is required.
3.6 After securing the clamping ring, reassemble the gearwheel and
circlip on the shaft.
3.7 Refer to the diagrams below to check for correct clearance and
alignment.

STEP 4
Fit drain tube
4.1 Remove the plastic plug from the drain port tting and push the
drain tube [A12] into the tting until it stops. Lead the drain tube
below deck to a low point in the boat where it can drain to the
bilge, then cut o any excess length. At most there should only
ever be a drop or two of water from condensation that will pass
through the tube.
Warning!
The positive cable (+RED) must be connected to the positive (+RED) terminal of the motor. Incorrect polarity will cause
permanent damage to the motor.
Battery compatibility
Andersen Compact Motors™ produced from 2011 onward are compatible with wet cell, AGM and gel batteries. Furthermore
they may be used with Lithium-ion batteries supplied by Super B™, MasterVolt®and Victron®. These batteries have been
tested for compatibility and have built-in protection to prevent damage to the motor, battery and other elements of the
system. Other brands of Lithium-ion batteries are NOT approved for use with Andersen Compact Motors™.
Super B™ is a trademark of Super B International B.V.
MasterVolt®is a registered trademark of MasterVolt International B.V.
Victron®is a registered trademark of Victron Energy B.V.
Operation
The Andersen Compact Motor™ electric winch uses a brushless DC motor. Brushless DC motors draw current from the
battery when operating, and can send current back to the battery when spinning down unloaded. Avoid operating the
winch using the motor at high speed with no load on the drum, as spinning down an unloaded motor from high speed
can stress the motor and battery and could result in reduced service life or damage to the motor, battery or other elements
of the system.
Further Considerations
• Always disconnect power when not in use, and before performing any service or maintenance work on an
electric winch.
• Use only an original Andersen control cable to connect the push button to the Compact Motor™.
Extension cables may be ordered separately.
• Use only the Andersen circuit breaker supplied with your Compact Motor™; do not use it with other devices.
• Supply power to the motor only from the battery; never from an external power supply.
• Refer to the wiring diagram and cable size recommendations in the Andersen Winch Data Sheet for the model
and voltage corresponding to your Andersen Compact Motor™ Electric Winch.
• Never use solvents for cleaning control cables or wires – use only alcohol for this purpose.
Failure to observe these notices will invalidate the warranty.
Important Notes - Electrical Installation
Incorrect electrical installation will result in permanent damage
to the motor and invalidation of the warranty.
STEP 5
Install push button
The push button requires 50mm (2”) clearance depth below the
mounting surface. It is supplied with a short 190mm (7 1/2”) long
cable lead; this is connected below deck to the 1000mm (39”) long
control cable [A10] and then to the short cable leads from the motor.
Extension cables are available and may be ordered separately if
necessary.
5.1 Select the desired location. For safety reasons it is
recommended that the push button [A1] is located in close
proximity to the winch, preferably within reach.
5.2 Determine the preferred orientation of the hinged cover (on
vertical surfaces it should open upwards). Then using the
drilling template or the rubber gasket [A2] as a guide, drill a
Ø25mm (1”) hole.
5.3 Drill a Ø3mm (1/8”) hole in each of the three mounting screw
locations.
5.4 Fit gasket and push button in place. Secure the push button unit
with the 3x M4x20mm self tapping screws [A8], using a small
amount of sealant at each hole.
5.5 Ensure that the breather channel on the side of the through-deck
tube of the push button is clear and free of dirt or sealant.

STEP 6
Prepare the power cables
6.1 Choose the shortest and most direct route possible for the cables, in order to minimise voltage drop between the
battery and the motor.
6.2 Measure the distance from the battery to the motor, and back again via the circuit breaker, to determine the necessary
total cable length.
6.3 Consult the table in the Winch Data Sheet for the model and voltage corresponding to your Andersen Compact Motor™
Electric Winch, to determine the minimum wire size for your cables according to the total cable length required for your
installation. If in doubt, consider choosing a thicker cable as this will help to minimise voltage drop.
6.4 Make up the cables with lugs to suit the terminals of your battery and the M8 terminals of the motor and circuit
breaker. The circuit breaker can accept cable lug size for max. wire size 50mm2.
STEP 7
Install the circuit breaker
7.1 Choose a suitable location for the circuit breaker [A11] in
an easily accessible position as close as possible to the
battery.
7.2 Connect the two thermal sensor wires from the motor to
the terminals marked “TER. SW” on the back of the circuit
breaker.
7.3 Use a 0.75mm2wire to connect the terminal marked
“MINUS” on the back of the circuit breaker to the
NEGATIVE (–) terminal of the battery.
Ensure that the circuit breaker is switched
to the “OFF” position before making any
wiring connections.

then lift o the self-tailing arm and the drum to expose the
centre stem and gears, and remove the base cover ring. Position
the centre stem of the winch on the deck plate with mounting
holes aligned, and secure it to the deck plate. Then secure the
base cover ring and t the drum.
STEP 9
Check installation
9.1 The PCB at the rear of the circuit breaker is tted with 3 LED
indicators, located along its edge as indicated in the photo.
Yellow LED
The yellow LED may signal a status code by emitting a
sequence of ashes once every 20 seconds. Count the
number of ashes and refer to the Troubleshooting
section of this manual.
Red LED
The red LED ashes when a fault has been detected.
Refer to the Troubleshooting section of this manual.
Green LED
In normal operation the green LED illuminates
continuously for the rst 5 minutes after switching to
“ON”, and ashes once every 20 seconds thereafter.
It will stop ashing a few seconds after switching the
circuit breaker to “OFF”.
Fault Possible Causes Action
Green LED does not illuminate. Circuit breaker is OFF, or there is a poor
connection of MINUS wire from the circuit
breaker to NEGATIVE (-) battery terminal.
Verify the connection of the MINUS
wire, see step 7. Then check that the
circuit breaker is ON.
Green LED remains illuminated
continuously for more than a
few seconds after switching
circuit breaker to OFF.
Cables on the circuit breaker terminals
labelled MOTOR and BATTERY have been
inverted.
With the circuit breaker OFF, swap the
cable connections to these terminals on
the circuit breaker and then try again.
Red LED ashes 4 times,
followed by Green and Yellow
both ashing.

Troubleshooting
Compact Motor™ electric winches have built-in monitoring and protection features to enhance safety and avoid permanent
damage to the electronic and mechanical components of the motor and winch.
Automatic cut-out and reset
The integrated controller will cause the motor to stop without tripping the circuit breaker if one of the following conditions is
detected:
• Maximum pulling load exceeded. The motor will cut out if the pre-set maximum pulling load of the winch for electrical
operation is exceeded. Operation can resume within a few seconds when the load returns below the limit.
• Overheating. The motor will cut out if the temperature of the motor circuit reaches 60˚C (140˚F). Operation can resume
when the temperature returns to normal, which may take some time.
• Maximum continuous run time exceeded. The motor will cut out after running continuously for 4 minutes and 15
seconds. Operation can resume after releasing the push button for a pause of at least 30 seconds.
In these cases, the illuminated push button will ash, indicating that the controller will reset automatically when operating
conditions return to normal.
Fault detection and identication
If a fault occurs that requires investigation or intervention, the LED indicators on the circuit breaker can assist with
troubleshooting and diagnostics. These indicators are located along the edge of the PCB, at the rear of the circuit breaker as
shown in step 9 of this manual.
FAULT POSSIBLE CAUSE ACTION
Excessive vibration or noise
from motor/gearbox unit.
Drive shaft housing not mating
properly with octagonal recess
in deck plate, clamping ring not
tightened properly.
Ensure proper assembly with deck plate, and
sucient clearance with through-deck hole – see
step 3. Ensure clamping ring is fully tightened
before inserting and tightening locking grub screw.

LED Status Codes / Diagnostics
Periodic lubrication of the
motor drive shaft lip seal:
Lubrication of the motor drive shaft lip seal is recommended
once a year to condition the lip seal and avoid water ingress.
To access the seal for lubrication, remove the winch from
the deck plate.
Liberally apply a high quality bearing grease such as Klüber
Isoex® TOPAS NB52. Andersen Winch Grease may also be
used for annual lubrication.
Isoex® is a registered trademark of Klüber Lubrication München SE & Co. KG
Periodic replacement of the motor drive shaft lip seal
Replacement of the motor drive shaft lip seal is recommended every 3 to 5 years, depending on usage, in order to avoid
water ingress and ensure a long and trouble-free service life. In practice every 5 years will be sucient for most users, while
the shorter interval is advisable for winches that see more constant usage or are installed in more exposed installations.
A service kit is provided with your new Compact Motor™ for the rst lip seal replacement. It includes step-by-step
instructions for the procedure and all necessary spare parts.
Winch inspection & service
Inspection and service of your Andersen winch is recommended at two year intervals. For information consult the separate
product manual for your winch model which contains instructions, assembly diagrams and information about spare parts.
Product manuals are available for download from the Andersen website.
Service and Maintenance
Proper care and maintenance of your Andersen products will ensure many years of reliable service. For your Compact
Motor™ unit it is essential that the following service procedures are carried out at the recommended intervals.
Safety First! Always disconnect power before performing any service
or maintenance work on an electric winch.
Liberally apply a high quality bearing grease
