Motor Installation
1. If required remove the adapter plate from the motor bracket
2. Insert the lower part of the flexible coupling and tighten the set screw. Measure the height of the upper flexible coupling on the motor shaft.
3. Calculate and insert the lower flexible coupling on the gear leg at the correct height as per graphic and insert the red “plastic ring” in the lower
part.
Example:
height A = 24,54mm.
height B = 24,54mm + 1mm = 25,54mm.
The correct placement of the lower flexible coupling unit should be 25,54mm measured from the top surface of the motor bracket to the
bottom inner surface of the lower flexible coupling.
(NB: The extra 1mm is added to eliminate the risk of compression to the rubber
element between the two couplings.)
4. Fasten the coupling set screw to the lower flexible coupling and apply blue Loctite.
(NB: Ensure the axle key and key-way in the flexible coupling
are aligned.)
5. Install the motor onto the motor bracket ensuring the couplings are engaged together correctly (top and bottom).
(NB: The motor can be placed
in all directions on the motor bracket. However, ensure the cable terminals are accessible for electrical installation later.)
6. If you are installing the motor at an angle of more than 30º off vertical, the motor will require separate/ additional support.
(NB: Do not position
supports on the motors top cap.)
7. Fasten the bolts holding the motor to the motor bracket with the above torque.
8. Check the drive shafts are engaged by rotating the propeller.
(NB: Rotating the propellers can be hard due to the gear reduction and the motor,
however the propeller must be able to rotate via hand power.)

IMPORTANT
The thruster motor assembly must be protected using suitable covering to avoid dust/debris ingress from fabrication/maintenance/shipbuilding
operations. On completion of operations, the cover must be removed before operating the thruster.

Electrical Installation
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 electro-motor flange and the positive terminal on the motor.
2. There is no electrical connection between electro-motor flange and the negative terminal on the motor.
If unsure contact skilled personnel.
1. Plan the location of electrical components before starting with the electrical installation. Main electrical components will typically consist of
battery, Automatic Main Switch (AMS) or manual main switch, Proportional Power Controller (PPC) and motor, see Wiring Diagram chapter for an
overview.
2. Estimate the total length of the power cables to determine the recommended cross section. The total power cable length is defi ned as
the distances from the positive battery pole, via fuse, main switch and PPC to the motor and all the way back to the negative battery pole.
Compromising the cable sections named B+, M- and B- on the drawing in the Wiring Diagram chapter.
3. Find the recommended power cable cross section for you installation by using the estimated total power cable length and the table shown in
Electrical Reference Guide
chapter
4. Find the recommended fuse size by using the table shown in
Electrical Reference Guide
chapter. Use slow blow rated fuses to hold stated nominal
current for minimum 5 minutes.
5. Use appropriate dimensioned battery with Cold Cranking Amps (CCA) according to recommendations in
Electrical Reference Guide
chapter.
Battery voltage must be compliant with the voltage rating of the thruster motor and control circuitry. Capacity and rated discharge current of
battery should be according to rated nominal current drawn and typical duty cycle for thruster operation. Nominal current drawn is listed in the
Cross Section Guide for Power Cables chapter. The actual voltage at the motor while running the thruster determines the motor RPM and thrust.
Use larger cable cross section and high-capacity battery for improved performance.
6. Install the cable from the as described in chapter Installation of Actuator Cable.
7. Install the PPC according to instructions in PPC Installation chapter.
8. Install and connect the battery, fuse, main switch and wiring according to instructions in 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 pole connection. The main
switch must be installed such that it is easily accessible to disconnect the thruster when not on-board or in the case of an emergency.
Follow the instructions in the Motor Lug Connection chapter when fastening the power cables to the motor.
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 does also turn on the automatic main switch. When the control panel is turned off the
automatic main switch is also turned off. This ensures that the control electronics and motor is only energized when the control panel is turned on.
Sleipner offers AMS supporting either S-Link or ON/OFF control panels. Ensure to select a main switch with voltage rating according to the chosen
motor- and battery-voltage. Note that the AMS requires separate power supply which should be protected by a dedicated fuse.
