Electrical Installation
WARNING
Check the following with the main switch is set to off. After all electrical connections have been completed check with an ohm meter that
there is no electrical connection between
1. electro-motor flange and the positive terminal on the motor
2. electro-motor flange and the battery negative terminal on the motor
(If unsure contact skilled personnel.)
1. Plan the location of all electrical components before starting with the electrical installation. Main electrical components will typically consist of
battery, fuse, main switch, Proportional Power Controller (PPC) and Control Box, see Wiring Diagram chapter for an overview.
For safety reasons it is always recommended to install a fuse and a main switch on the power cable and as close as possible to the positive battery
pole. Distance between battery and fuse should be less than 1 meter. The main switch must be installed such that is easily accessible to disconnect
the thruster when not on-board or in the case of an emergency. 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 and current ratings according to the specifi cations of the chosen thruster motor. Note that the AMS requires separate
power supply which should be protected by a dedicated fuse.
For installations which requires ignition protected equipment ensure to use ignition protected fuse and main switch. Ensure to follow your national
regulations.
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 Control Box 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. Note that maximum cross section that fi ts through the grommet of the Control Box is 70mm2. Maximum
cross section that fi ts with the power cable terminal inside the Control Box is 50mm2. If a 70mm2 cable is used some of the wire strands must be
cut off to fi t the cable inside the terminal. If recommended cross section exceeds 70mm2 it is recommended to use as short as possible cables
between PPC and Control Box with maximum 70mm2 cross section. The recommended cross section or larger should then be used for the rest of
the power cables.
4. Find the recommended fuse rating 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. Select appropriate dimensioned battery with Cold Cranking Amps (CCA) according to 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 Electrical Reference Guide chapter. The actual voltage at the motor while running the thruster determines the motor RPM and thrust.
Cable losses can reduce the voltage level and result in reduced thrust. Use larger cable cross section and high-capacity battery for improved
performance.
6. Install the Control Box according to instructions in Control Box Installation chapter.
7. Install the control panel according to instructions in the installation manual of the selected Control Panel.
8. Install the battery, fuse, main switch and wiring according to instructions in Wiring Diagram chapter and installation manual of selected fuse and
main switch.
