For thruster systems
• Do not install the thruster in a position where you need to cut a stiffener/ stringer/ support that may jeopardise the hull integrity without checking
with the boat builder this can be done safely.
• We advise painting the gear house and propellers with anti-fouling. (NB: Do not paint the anodes, sealing, rubber fi ttings or propeller shafts)
• There is only room for a thin coat of primer and two layers of anti-fouling between the tunnel and the props.
• Never run the thruster out of water without load.
The installer must read this document to ensure necessary familiarity with the product before installation.
Instructions in this document cannot be guaranteed to comply with all international and national regulations. It is the responsibility of the
installer to follow all applicable international and national regulations when installing Sleipner products.
The recommendations given in this document are guidelines ONLY, and Sleipner strongly recommends that advice is obtained from a person
familiar with the particular vessel and applicable regulations.
This document contains general installation instructions intended to support experienced installers. If you are not skilled in this type of work,
please contact professional installers for assistance.
If required by local regulation, electrical work must be done by a licensed professional.
Appropriate health and safety procedures must be followed during installation.

General Installation Consideration and Precaution Guidelines
When installing an S-Link™ system connect ONLY original Sleipner S-Link™ products or other authorized control equipment directly to the S-Link™ bus.
Connecting non-authorized third-party equipment, it must always be connected through a Sleipner supplied interface product.
Any attempt to directly control or connect into the S-Link™ control system without a designated and approved interface will render all warranties and
responsibilities of all of the connected Sleipner products. If you are interfacing the S-Link™ bus by agreement with Sleipner through a designated
Sleipner supplied interface, you are still required to install at least one original Sleipner control panel to enable efcient troubleshooting if necessary.
MC_0105
MC_0502
Lithium Batteries for proportional thrusters models
• If a lithium battery system is installed for supply of proportional thrusters, ensure the battery is designed for continuous supply of the required
thruster current. Under-rated battery management system can suddenly disconnect the load which may lead to dangerous situations. The
 rmware version of Proportional Power Controller (PPC) must be of version 1.033 or later if the PPC is to be connected to a lithium battery.
Operating the thruster outside speci ed ratings will void warranty.
NEVER Disassemble any part of the Ignition Protected assembly. Tampering with the Ignition Protected assembly will cause it to lose this
safety feature. If there is a problem with your Ignition Protected motor, please contact your dealer. MC_0007
MC_0425
For thruster systems
• Do not install the thruster in a position where you need to cut a stiffener/ stringer/ support that may jeopardise the hull integrity without checking
with the boat builder this can be done safely.
• We advise painting the gear house and propellers with anti-fouling. (NB: Do not paint the anodes, sealing, rubber fi ttings or propeller shafts)
• There is only room for a thin coat of primer and two layers of anti-fouling between the tunnel and the props.
• Never run the thruster out of water without load.
MC_0474
For retract thrusters
• Stern mounted retract thrusters must not be installed to conflict with the main boat propellers or its water trail. (NB: consult a naval architect for
an exact position.)

Bow
The thruster must be installed as far forward as possible. Allow for 100mm around the thruster for moulding the retract frame and the depth of the
propeller when extended is a minimum of the vaule defined below under the waterline.
For bow installations, the thruster must be installed in the centre line of the keel.
(NB: Installing the thruster further forward will give less depth for the propeller but offer better leverage effect for turning.)
Stern
The thruster must be installed as far forward as possible. Allow for 100mm around the thruster for moulding the retract frame and the depth of the
propeller when extended is a minimum of the vaule defined below under the waterline.
The thruster while retracted must not conflict with any other component of the vessel such as stern drives/ propellers, trim tabs or rudders. Therefore
stern installations do not require to be installed on the hulls keel centre line and can be installed off centre.
Installing the thruster below the waterline as outlined is important for two reasons:
1. So that it does not suck air down from the surface which will reduce performance and increase noise levels.
2. To get as much water pressure as possible to receive maximum efficiency from the thruster.
Always ensure enough space for the complete SR unit including motor, actuators, retract frame, future service and for installation moulding to the hull.
The thruster must always be installed so the hatch is opened towards the direction of travel.

Preparing a Sandwich Hull for Retract Systems MC_0067
For vessels with sandwich hull construction, additional reinforcement of the area around the retract flange is required.
1. To achieve maximum strength and bonding in the area around the installation of the retract thruster remove the inner and core material to expose
the outer laminate. Remove enough area for a 100mm (minimum) clearance surrounding the retract thruster housing.
2. Reinforce the area with bonding to strengthen the hull for the operation of the retract thruster.
3. During the process of attaching the retract thruster housing build this area up to ensure enough strength of the hull.
(NB: Consult an experienced boat builder)

Marking and Trimming of SRF Flange
1. Identify the location of the thruster considering space required for installation, operation and future maintenance.
2. Mark the keel centre line on the inside of the hull. Flip the SRF flange upside down and use the internal surface to mark the hull for cutting the
thruster hatch. (NB: Ensure the mould is centred. For stern installtion the hull is normally flater in this area. To avoid conflicts with propeller
systems the thruster can be offset from hull center line. Consider water flow direction from the thruster, adjusting horizontal level of the
thruster to achieve free flow from the propeller tunnel and ensure free water flow direction inwards.
3. The SRF flange must sit so the two side rails run flush with the length of the hull. To do so the SRF flange tabs must be trimmed down to match the
hull pro le curvature. (NB: Consult a naval architect for methods to transfer the hull profi le to the SRF flange. DO NOT cut the SRF flange length
edge.)
4. Cut the hatch door. The hatch opening must be cut at an angle of 45º on three sides and 30º on the bow face. This allows any water forces hitting
the hatch while closed to be absorbed by the hull, not the thruster. (NB: Use a suitable cutting tool able to be set to the desired angle. If cutting
from outside the hull drill 4 holes from the internal marked corners to see the required profi le from the outside.)

Installation Pre-check
Temporarily set up the complete installation to ensure no conflicts during the  nal operation of the thruster.
1. Use epoxy  ller in the 4 corners of the SRF flange and set it over the hatch. Attach the retract housing retract flange with 4 corner screws to hold.
Use polyester or resin to attach the hull hatch to the retract unit. (NB: Ensure correct orientation for the thruster to open the hatch facing the
direction of water flow. Remember attachment is for temporary checking of thruster operation only.)
2. Temporarily connect DC cables (NB: Refer to the label on actuators for correct voltage) to the cables on the terminals on the controller. Set switch
no. 4 on the DIP-switch marked “SETTINGS” to ON. Deploy thruster and remove the red distance part located above the tunnel.
3. Press “DOWN” to extend the tunnel and check the hatch opens fully without touching the hull. If the hatch is obstructed by the hull in the front,
lift the aft end of the SRF flange maintaining the reference height in front - until the hatch clears the hull when opened.
4. Press “UP” to retract the tunnel. Ensure when the hatch is closed extra pressure is on the contact surface between the hatch and the hull only. If
the hatch is not closing with pressure on the contact surfaces the entire SRF flange must be raised.
After all, pre-checks are completed the retract system can be installed.
MC_0068
IMPORTANT
The hatch contact edges and the hull contact edges MUST work as the mechanical end stop. During cruising, slamming forces from the water must
be absorbed by these areas, not the thruster.
Accidental activation of the retract mechanism can cause serious injury due to the high-pressure
force used for moving the hatch. IF operating the hatch during during any work/ maintanace around
or inside the retract hatch, USE CAUTION.

To increase the space between the hatch and the hull the entire SRF flange and motor must be raised at the stern end.
1. With the hatch in the open position raise the stern end of the SRF flange and motor until the appropriate clearance is achieved. (NB: continue to
raise the stern height until this is obtained.)
2. Use a wedge to keep the thruster stable.
3. Open and close the hatch to ensure:
- Clearance between the hull and hatch when the thruster is open
- Hatch closes flush with the hull with full contact between hatch and hull.
4. Record the height and keep the wedges in place and secure the position of the SRF flange with epoxy  ller in the corners with epoxy  ller in the

SRF Flange Installation
Start the laminating with a strong attachment point in each corner between the hull and the outside of the lower unit. Use epoxy and  breglass cutting
or similar, which laminating material is the boat builders responsibility.
1. Before grinding of hull and SRF flange, precautions must be taken against grinding dust inside the boat. Surfaces to be moulded/ bonded must be
grinded to remove coating and material to achieve suf cient adhesion.
2. Apply epoxy  ller or equivalent on bottom edges of SRF flange or on the hull for bonding between connection surfaces. Ensure the  ller is
compatible with hull materials.
3. Place the SRF flange into position ensuring the correct orientation. If there are gaps between SRF and hull  ll with extra epoxy  ller or equivalent.
Grind and smooth the surfaces after curing time.
4. Laminate the insde and outside of the SRF flange solid to the hull by applying. Apply several layers of  breglass and ensure that the resin and
 breglass is compatible with hull materials.
5. After curing time, smooth all moulded surfaces and apply coating. Apply putty before coating if necessary.
After moulding in SRF flange is completed, the upper thruster case is ready to be installed.

SRF Flange Installation
Start the laminating with a strong attachment point in each corner between the hull and the outside of the lower unit. Use epoxy and  breglass cutting
or similar, which laminating material is the boat builders responsibility.
1. Before grinding of hull and SRF flange, precautions must be taken against grinding dust inside the boat. Surfaces to be moulded/ bonded must be
grinded to remove coating and material to achieve suf cient adhesion.
2. Apply epoxy  ller or equivalent on bottom edges of SRF flange or on the hull for bonding between connection surfaces. Ensure the  ller is
compatible with hull materials.
3. Place the SRF flange into position ensuring the correct orientation. If there are gaps between SRF and hull  ll with extra epoxy  ller or equivalent.
Grind and smooth the surfaces after curing time.
4. Laminate the insde and outside of the SRF flange solid to the hull by applying. Apply several layers of  breglass and ensure that the resin and
 breglass is compatible with hull materials.
5. After curing time, smooth all moulded surfaces and apply coating. Apply putty before coating if necessary.
After moulding in SRF flange is completed, the upper thruster case is ready to be installed.

Motor to House Installation
1. Install the motor onto the motor bracket ensuring the couplings and the drive shafts have locked together. The motor must be installed with
the solenoid facing the control box. (NB: depending on your coupling you may need to wiggle the motor into place. Ensure the couplings are
engaging correctly. Ensure the motor cable terminals are accessible for electrical installation later.)
2. Fasten the bolts holding the motor to the motor bracket with the above torque.
3. Check the drive shafts engage by rotating the propeller. It is required the propeller can rotate via hand power. (NB: Rotating the propellers can be
hard because of the gear reduction and the motor.)
4. Apply the gear leg and propeller with anti-fouling designed for propellers. Do not apply to the propeller drive shaft, the anodes or the end of the
gear leg facing the propellers.
(NB: The motor must be covered to avoid dust from fabrication/ maintenance operation entering the motor or the solenoids. After fabrication
maintenance operations have ceased the cover must be removed before operating the thruster.)

Electrical Installation
1. Plan the location of electrical components before starting with the electrical installation. Main electrical components will typically consist of
battery, fuse, main switch and thruster motor, see Wiring Diagram chapter for an overview.
Sleipner offers both manual main switches and Automatic Main Switches (AMS). Sleipner AMS is controlled by the control panel in addition to
the option of manual operation. Turning on the control panel also turn on the automatic main switch. When the control panel is turned off the
automatic main switch is turned off. This ensures that the control electronics and motor are only energized when the control panel is turned on.
Sleipner offers AMS supporting either S-Link or ON/OFF control panels. Note that the AMS requires a separate power supply which should be
protected by a dedicated fuse. Ensure to select an AMS with a voltage rating according to the chosen motor- and battery voltage.
Electrical products installed in gasoline engine spaces or other areas potentially exposed for explosive gases must be Ignition Protected.
Products installed in such locations should conform to the ISO 8846, SAE J1171 or UL 1500 standard.
Common ground connection is required for dual thruster installations with two battery banks.
2. Estimate the total length of the power cables to determine the recommended cross-section. The total power cable length is de ned as the
distance from the positive battery terminal, via fuse, main switch, and thruster motor, and all the way back to the negative battery terminal.
3. Find the recommended power cable cross-section for the installation by using the estimated total power cable length and the table shown in the
chapter Electrical Reference Guide.
4. Select the recommended fuse size by using the table shown in the chapter Electrical Reference Guide.
5. Use an appropriate dimensioned battery with Cold Cranking Amps (CCA) according to recommendations given in the Electrical Reference Guide
chapter. Battery voltage must be compliant with the voltage rating of the thruster motor and control circuitry. The capacity and rated discharge
current of the battery should be according to the rated nominal current drawn and the typical duty cycle for thruster operation. The nominal
current drawn is listed in the Electrical Reference Guide chapter.
The actual voltage at the motor while running the thruster determines the motor RPM and thrust. Using a smaller cross-section than
recommended or a low-capacity battery could reduce performance.
Installing a battery close to the thruster reduces the length of the power cables and potentially increases the performance, due to lower voltage
drop in the power cables. For installations on large vessels with bow and stern thrusters or catamarans a dedicated battery for each thruster
should be considered.
6. Install and connect the electrical components according to the applicable Wiring Diagram chapter.
For safety reasons it is always recommended to install a fuse and a main switch on the power cables and as close as possible to the positive
battery terminal. The main switch must be installed such that it is easily accessible so that the thruster can be electrically disconnected to a safe
state when not on-board or in the case of an emergency.
For dual thruster systems using only one battery bank a dedicated fuse and main switch should be installed for each thruster. These should be
installed close to the battery bank.
Follow the instructions in the Motor Lug Connection chapter when fastening the power cables to the motor.
7. Fuse and main switch should be installed according to the installation manual accompanying the products.
8. Install the control panel according to the instructions in the Installation Guide included with the control panel.
WARNING
After all electrical connections have been completed, turn off main switch and check the following with an ohmmeter:
1. There is no electrical connection between motor flange and the positive terminal on the motor.
2. There is no electrical connection between motor flange and the negative terminal on the motor.
If unsure contact skilled personnel.

eVision thrusters have high ef ciency and can therefore offer long run times. The proposed cable cross sections in above table are only for reference.
Dependent on system voltage, the stated nominal current is measured with 21V or 42V at the motor terminals.
Lover voltage level at the motor terminals will increase the current drawn by the thruster. To avoid signi cant voltage drop and excessive heat
generation in cables and other system components selection of battery and cable cross section is critical.
Higher current consumption can also be caused by incorrect thruster installation and marine growth in the tunnel and on the propeller.
For each installation an experienced electrician should be consulted for cable cross section calculations and selection of fuses, main circuit and
batteries.

S-Link System Description
S-Link is a CAN-based control system used for communication between Sleipner products installed on a vessel. The system uses BACKBONE Cables
as a common power and communication bus with separate SPUR Cables to each connected unit. Only one S-Link POWER cable shall be connected to
the BACKBONE Cable. Units with low power consumption are powered directly from the S-Link bus.
Main advantages of S-Link system:
- Compact and waterproof plugs.
- BACKBONE and SPUR Cables have different colour coding and keying to ensure correct and easy installation. BACKBONE Cables have blue
connectors and SPUR Cables have green connectors.
- Different cable lengths and BACKBONE Extenders make the system scalable and flexible to install.
Installation of S-Link cables:
Select appropriate cables to keep the length of BACKBONE- and SPUR Cables to a minimum. In case of planned installation with total BACKBONE
Cable length exceeding 100 meters please consult your local distributor. The S-Link cables should be properly fastened when installed to avoid
sharp bend radius, cable cha ng and undesired strain on connectors. Locking mechanism on connectors must be fully closed. To ensure long lifetime,
cables, T-Connectors and Extenders should not be located so that they are permanently immersed in water or other fluids. It is also recommended to
install cables such that water and condensation do not run along the cables and into the connectors.
The POWER Cable should ideally be connected around the middle of the BACKBONE bus to ensure an equal voltage drop at each end of the
BACKBONE Cable. The yellow and black wire in the POWER Cable shall be connected to GND and the red wire connected to +12VDC or +24VDC.
To reduce the risk of interference, avoid routing the S-Link cables close to equipment such as radio transmitters, antennas or high voltage cables. The
backbone must be terminated at each end with the END Terminator.
SPUR cables can be left unterminated to prepare for the installation of future additional equipment. In such cases, ensure to protect open connectors
from water and moisture to avoid corrosion in the connectors.
