Bow thruster
The configuration as supplied is for application as a bow thruster.
Stern thruster
Configure a stern thruster by putting the switch on the inside of the
cover into the correct position.
• Reinstall the cover and tighten the glands.
Main power fuse 2
In the connection unit, there
is a main power fuse on the
controller.
This fuse protects the con-
troller and motor against
short
circuit/overloading
and it must remain present
under all circumstances.
When replacing the fuse, the replacement must be of the
same rating.

Connecting CAN bus (control current) cables
See diagrams from page

if multiple panels have to be connected.
The CAN bus power supply must always be connected to
12 Volt (≥10 V, ≤16 V). Use the E-Drive MPE1KB key switch as
power supply.
As required by international standards, all neutral (negative)
conductors of the DC system must be connected to one central
point. This prevents not only dangerous situations and corrosion
problems, but also error messages in the CAN bus system.

Troubleshooting
Please note that his is a general instruction. Specific actions may
slightly differ from one type to another.
Check, and if necessary correct, the following items if the system is
not working properly.
6.1
CAN bus system
• Is the power supply switched on?
• Is the CAN bus supply voltage correct? (=12VDC).
• Does the control panel switch on?
• Are both terminating resistors correctly positioned?
Note: The CAN bus power supply has an integrated terminating
resistor.
• Did all connectors "click" when inserted in the connection point?
• Are the correct CAN bus cables used and in good condition?
• Are the correct CAN bus connectors used and in good condition?
• Does the total length of the CAN bus network not exceed 40 me-
ters?
• Is each "node" connected to the power supply? Check by measur-
ing the voltage on the 2 opposite pins in the connector on the
node (pin 1=12 VDC positive, pin 3=12 VDC neutral).
6.2
Thruster installation
• Is the battery supply switched on?
• Is the supply voltage of the thruster correct? (measure the voltage
at the motor controller terminals).
• Is the thruster correctly configured? (bow or stern thruster).
• Do both the positive and neutral cables have the correct diameter
and length?
• Are both the positive and neutral wires connected to the correct
terminals of the thruster motor controller?
• Are both the positive and neutral wires correctly routed? Incorrect
routing may cause the wire(s) to press against the circuit board,
which can lead to malfunctions.
• Is the pressed cable lug of the neutral cable isolated from the
nearby motor winding connections? (spacer ring installed?)
Note: Not applicable to bow thrusters with external cable connec-
tions.
• Are the cable glands of the power supply cables firmly tightened?
• Is the white connector for the thermal sensor of the motor cor-
rectly connected to the circuit board under the top cover?
• Is the fuse (5 A) of the motor controller in place?
• Is the connector running from the top cover circuit board to the
thruster motor controller fixed and are all connector pins correctly
connected? (latch in place?)
