Warnings
The design and configuration of your Copenhagen Subsea thruster might differ from the thruster pictured
in this manual.
Disconnect the thruster from power when handling it.
Operate the thruster under water only. The warranty will not cover damages resulting from
running the thruster without water to lubricate its bearings.
Connect the aluminum housing of the thruster to a sacrificial zinc anode to prevent corrosion.
If the thruster is exposed to liquids other than seawater or freshwater with a PH value between 6
and 9, the warranty will not cover any direct damages or any following damages.
Make sure the motor temperature is always below 70 degrees Celsius.
Use only Copenhagen Subsea A/S specially designed transport boxes for transportation.
Under no circumstance disassemble the rotor from the stator without using the appropriate tools
as described in this manual as this may cause personal injury due to the strong magnetic forces
that hold the rotor in place.
Be aware of the thruster is delivered with no propeller safeguarding to prevent access to the
rotating propeller to protect against human injuries. Therefore, consider mounting a propeller
guard when installing the thruster into your application or take other safety precautions.
During operation the thruster needs to be fully submerged in water.

Mounting the Thruster
•Use the four holes pattern on the mounting flange when mounting the thruster.
•Make sure the mounting bracket on your application is robust and stable.
•See drawing below for mounting holes pattern
•Use a bit of AquaShield grease on the thread of the M8 mounting bolts when mounting the
thruster.
•The material of the bolts has to be A4 and with the help of a torque wrench (18 Nm) screw in the
bolts in a criss-cross tightening sequence.
•The bolt must be mounted so that it has at least 12mm of its thread inside the mounting flange.
•It is essential to occasional retighten the mounting bolts with help of a torque wrench (18 Nm)
Mounting holes pattern for:
VS, VM, VL and VXL thrusters

Electrical Isolation of the Thruster when Mounting
It is important to electrocally isolate the thruster when mounting the thruster onto the application. The
reason for this is to avoid corrosion and cathodic debonding. When ordering a propulsion solution from
Copenhagen Subsea, the necessary equipment to electrically isolate the thruster is included. For each
thruster unit following set of washers follows:
•2x plastic shoulder washers
•1x flat plastic washer
Depending on the thickness of the mounting bracket, different set of washers shall be used.
•If the mounting bracket is thick enough to use a shoulder washer on both sides of the mounting
bracket – the following set of washers are needed: (2x plastic shoulder washers)
Insert the plastic shoulder washer on both side of the mounting bracket and add a steel washer
between the mounting bolt and the plastic shoulder washer.
•If the mounting bracket is too thin to insert a shoulder washer in both sides on the mounting
bracket – the following set of washers are needed: (1x plastic shoulder washer & 1x flat plastic
washer)
Insert the shoulder washer between the thruster and mounting bracket. Hereafter, add the flat
plastic washer and a steel washer between the mounting bolt and the mounting bracket.

Main Water Inlet
To detect the main water inlet side of the thruster, look for the screws on the inside of the propeller. The
main water inlet is on the opposite side of the propeller blades from these screws.

•Macartney - Subconn - https://www.macartney.com/what-we-offer/systems-and-
products/connectors/subconn/
Subconn
If the thruster is provided with a SubConn connector, please find the correct connector and read the
information below.
SubConn10 pins
In order to supply the motor with sufficient power from the motor controller, each of the 3 phases of the
thruster has been divided over two seperate pins on the connector:
