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 the illuminated “intelligent” push button
which regulates speed and power 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.

52ST Above Deck Compact Motor™
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 Mounting of an Above Deck Compact Motor on a vertical
surface is not ideal as it increases exposure to potential
problems of excessive moisture and water ingress. It is
important to take care to protect the unit from unnecessary
exposure, and carry out seasonal maintenance and regular
lubrication of the motor shaft seal.
1.3 The winch should be positioned with the recommended line
entry angle of 3-8° from horizontal.
1.4 Refer to the Winch Data Sheet for your winch model for
clearance/space requirements for the wiring and drain tube
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.
1.5 Note the location of the drain port in the base of the motor -
see page 13. 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 [A11] will be
attached to this port to allow any moisture from condensation
to escape and drain to the bilge. The position of the drain port
is also indicated on the drilling template.
1.6 The self-tailing arm should be positioned to allow the rope
to drop clear of the winch as it feeds out of the self-tailer.
Positions will typically be as indicated by the shaded sectors
in the diagram.

STEP 2
Prepare the mounting surface
2.1 After determining the mounting location and orientation, clean
the mounting surface and use the drilling template [A3] as a
guide. Ensure that the surface is at and there is adequate
space and clearance for operation of the winch.
2.2 With the drilling template in the desired orientation, drill the
mounting holes as indicated on the template. NOTE: The
through-deck holes are Ø6.5mm holes for the M6 mounting
bolts (or Ø9/32” holes for 1/4” bolts), however the bushes that
protrude from the motor base require 10.5mm (13/32”) diameter
clearance to a depth of 11mm (7/16”)
2.3 Cut the required holes for the motor terminals, drain port and
wiring as indicated on the drilling template
2.4 Clean any wood or breglass splinters from the holes, and clean
the deck thoroughly to ensure deck sealant can adhere properly.

STEP 3
Prepare and dry-t the motor unit
3.1 Slide the stainless steel cover [2] upward to remove it from the
motor unit [1], taking care to ensure that the O-rings [3] & [4]
remain in position.
3.2 Fit the terminal extensions [A13] to the motor terminals,
ensuring that the RED extension is tted to the RED POSITIVE (+)
motor terminal, and the BLACK extension is tted to the BLACK
NEGATIVE (–) motor terminal.
3.3 Remove the plastic plug from the drain port tting and push the
drain tube [A11] 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.
3.4 Place the motor in position on deck, passing the push button
control cable and the two wires for the thermal sensor together
through the same hole. Ensure that deck cut-outs and fastener
holes align properly and there is adequate clearance for a good
t and assembly.

STEP 4
Install motor unit.
Having a second person to assist during this step may help to avoid fouling the wiring and drain tube with sealant as they are
passed through the deck.
4.1 Apply sealant to the deck to prevent water ingress. In addition to sealing the mounting holes, apply a bead of sealant
around the perimeter of the base to form a completely watertight seal.
NOTE: For mounting on metal surfaces, the base must also be completely isolated from the mounting surface to prevent
galvanic corrosion.
4.2 Fit the motor unit [1] to the deck using the appropriate length ISO 4762-A4-M6 or 1/4” bolts, large washers or backing
plate, and locking nuts.
4.3 Place the stainless steel cover [2] back on the motor unit and slide it down into position.
STEP 5
Install push button
The push button [A1] 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 [A9] 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 [A7], 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.

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.

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.
