1. SAFETY MEASURES
1.1 Electrical safety
When the hydrogenerator operates in a normal manner (the maximum speed is
not exceeded), the voltages generated by the generator and the charger will not
exceed 120VDC or 50VAC. Thus, the product operates in the extra-low voltage
area. Extra-low voltage is considered to be safe for the operator. However, the
operator is always responsible for monitoring the funconing of the product and,
if needed, disconnecng the charger and the hydrogenerator to prevent hazard
and damage.
The charging current causes power loss in the wires, resulng in warming of
the wires. Abnormal warming indicates a malfuncon in the equipment. If that
happens, the operator must immediately disconnue charging (stop the boat) and
invesgate the cause of the malfuncon. In the installaon stage, the charging
wires of the baery should always be connected last (the generator wires are
connected rst).
1.2 Installation safety measures
When determining the locaon to mount the product in the back of the boat, keep
in mind that the outboard unit weighs 7.5 kg. It is important to nd an opmal
locaon for mounng the product, since the locaon has a material impact on
performance. If possible, request another person’s assistance to ensure that the
product is mounted safely. If you mount the product while the boat is aoat, wear
the required safety gear (a safety vest, for example).
!
Verify the polarity of the charging wires (+, -) to ensure you perform
the connecon correctly. Damage to the charging unit is inevitable if it
is installed improperly. For more detailed installaon instrucons, see
secon 4.4 Installing the charger.
The posive (red, +) charging wire should always be equipped with a
circuit breaker (40A).
!

REMORAN™ WAVE 3
1.3 Restrictions concerning operation and the
operating environment
To prevent product breakdowns, the maximum operang speed of the boat is
15 knots. (Note! The charging unit stores data on the turbine rotaon speed and
uses this data to calculate the operang speed of the boat.) If the operang
speed approaches 15 knots, li the product up from the water or disconnect the
interior connector of the generator cable from the connector of the outboard
unit’s cable.
For the winter, the outboard unit must be dismounted from the boat and stored
in a warm (+5°C) area to prevent it from freezing. Do not operate or store the
product at temperatures below 0°C, since any water remaining in its structures
may freeze and thus break the product.
1.4 Safety measures concerning operation and the
operating environment
• Foreign objects such as seaweed entangled in the generator unit must be
removed immediately. Foreign objects (shnets, shing line, seaweed) increase
fricon and considerably increase the force the structures are exposed to.
• Note that in order to operate the product safely, the operator must inspect
the product regularly and carry out the required cleaning and maintenance
procedures.
• The product should be mounted on the boat in accordance with this manual
while observing precision and care.
• Check the outboard unit for any signs of impact or other mechanical forces.
• Check that the charging unit has been installed properly (both in terms of
electrical and mechanical requirements) and that it has not been exposed to
water.

2. PRODUCT INFORMATION
2.1 General description and operating principle
The hydrogenerator generates electrical energy when the boat is in moon. The
turbine of the outboard unit that is installed in the transom on the outside of the
boat rotates when the boat is in moon, running the generator located in the
lower part of the outboard unit. The generator produces low-voltage three-phase
electricity, which is conducted to a charger, installed inside the boat, through a
weather-resistant cable and a feedthrough connector. The charger converts the
electrical energy to a form feasible for baeries (12V or 24V) and also ensures that
the charging sequence of the baery is correct. The Remoran™ Charger 300W
supports Bluetooth® wireless technology which allows the user to connect the
charger to their own smartphone.

4.1 Summary of the mounting steps
1. The outboard unit is mounted to the boat using a mounng rail. The rail is
installed in the boat’s transom by means of bolts inserted through two holes
drilled through the transom. The heads of the bolts sele in the groove in
the rail and the fastening nuts are fastened to the bolt ends on the inside of
the boat. Seal the holes drilled for the bolts with sealant that is resistant to
sunlight and marine condions. (See secon 4.2 Installing the mounng rail
on the boat.)
2. A feedthrough connector must be installed in the deck of the boat or in the
transom near the generator so that the generator cable reaches it (Figure 4).
The generator cable poron that remains inside of the boat is integrated in
the connector. The connector requires a drilled hole that should be sealed,
and the connector is fastened to the deck by means of the wood screws
supplied. (See secon 4.4.2 Installing the cable feedthrough)
3. The charger must be installed inside the boat, and the generator
cable and the charging wires from the boat’s baeries should
be connected to it. Install a 40 A circuit breaker on the red (+)
charging wire as near the baeries or main switch as possible.
(See secon 4.4.4 Connecng the wires to the charger)
4. The turbine is supplied unaached and must be mounted on the generator
axle before use. (See secon 4.3 Mounng and dismounng the turbine)

REMORAN™ WAVE 3
4.2 Fastening the mounting rail to the boat
Since the outboard unit’s angle can be adjusted between 0 and 40 degrees, the
rail can usually be fastened directly to the transom of the boat. If the angle of the
transom is negave or wider than 40 degrees from the vercal axis, an adapter
must be prepared. If needed, contact the manufacturer for further informaon.
The mounng rail is subjected to considerable mechanical loads. Plan and prepare
the fastening of the rail carefully before starng work. The sales package includes
acid-resistant M8x50 bolts as well as M8 nuts and M8 washers, 2 pcs of each,
for fastening the rail. The length of the bolts is usually sucient for the purpose.
However, you should use longer bolts, if needed. Drill 8 mm holes.
It is recommended that on the inside of the boat, you use an addional reinforcement
board that is slightly larger than the rail so that it provides a sucient mechanical
locking acon and spreads the mechanical stress over a larger area. Apply sealant that
is resistant to sunlight and marine condions to the holes drilled through the transom.
Parts required and supplied in the sales package: (or an
accessory "Standard rail kit") (Figure 5)
• Mounng rail
• 2 pcs M8x50 bolts
• 2 pcs M8 washers
• 2 pcs M8 nuts
You will also need:
• Reinforcement board (for dimensions, see secon 4.
Mounng)
• Sealant

Selecting the installation location
The rail should be fastened near the boom edge of the transom or near
the addional supporng bulkheads. Select the installaon locaon so
that when the outboard unit is mounted on the rail, the turbine remains
submerged at all mes. We do not recommend installing the rail in
the line of the rudder due to the turbulence of the ow. Check that
there is sucient space behind the transom to install the rail and, when
needed, the addional reinforcement board. The distance between the
holes should be 10–15 cm. Use the reinforcement board as a template
and mark the locaons of the holes in the transom. (Figure 6). Leave
the lower end open at least at a distance equalling the thickness of the
boom. Drill the holes in the locaons marked in the transom.
Installing the rail in the holes
• Slide the heads of the bolts into the groove in the rail (Figure 7).
• Fit the bolts in the rail into the holes so that the blue plasc end of
the rail the faces down (Figure 8).
• Apply sealant to the stems of the bolts and the boom surface of
the rail.
• Press the rail ghtly into place so that the sealant keeps it from
sliding down before the nuts are ghtened.
• You can ensure that the rail stays in place during fastening the bolts
by asking someone to assist you or by taping the rail to the transom,
etc.
Be careful not to allow the rail to slip into the water
before the nuts are ghtened.

Reinforcement board and tightening
• Apply sealant around the bolts on the inside.
• Place the reinforcement board over the bolts.
• Insert the washers and nuts.
• Tighten the nuts evenly by alternately ghtening each one
(Figure 9)
4.3 Mounting and dismounting the turbine
(Figure 10)
5. Slide the turbine (2) onto the axle (1). Ensure that the turbine wedge
is aligned with the groove in the axle. When the turbine has been
installed correctly on the axle, there is a gap of approximately 3 mm
between the turbine and the generator.
6. Install an acid-resistant spring washer (3) under the acid-resistant
M6x30 Allen screw (4).
7. Insert the screw and the spring washer through the hole in the
turbine and use a hex key to ghten the turbine into place to a
torque of 4.0 Nm.
To dismount the turbine, loosen the screw and pull the turbine o the
axle. You can use thin screwdrivers or equivalent thin, at tools on the
opposite sides of the turbine to gently pry it o of the axle. Do not pull
or twist the turbine blades.

4.4 Installing the charger
4.4.1 Installation location considerations:
• The charger must be installed in a dry indoor area in the boat.
• Ensure that the charger is not exposed to water (e.g. dripping condensed
water, etc.)
• To install the charger, use 4 pcs of 4 mm thick wood screws. The length of the
screws depends on the installaon locaon.
• Cooling: During charging, the charger unit may warm up considerably.
Therefore, it is important to install the unit in a locaon where the ambient
temperature does not rise signicantly. Avoid installing it in the engine
compartment or a similar space. The charger should always be installed in
an upright posion to ensure unobstructed and sucient ow of air in the
cooling element. That is why the minimum distance of the charger to the
ceiling or other similar obstrucons to the air ow should be 20 cm. The
charger has a built-in temperature monitoring funcon. If the temperature
becomes too high, the charger reduces its charging power and, if needed,
stops the charging unl the temperature drops to a safe level. Therefore,
insucient cooling weakens the charger’s performance.
• To achieve the best eciency, all wires should be as short as possible.
• The cross-seconal area of the hydrogenerator cable wires should be a
minimum of 2.5 mm2 throughout their length.
• The cross-seconal area of the charging wires to be connected to the
baery should be 6–10 mm2 and the maximum length of the charging
wires should be 3 metres.
4.4.2 Installing the cable feedthrough
The Remoran™ Wave 3 sales package includes a weather-
resistant generator cable (4*2.5 mm2) integrated in the outboard
unit, as well as a cable to be installed in the space behind the
feedthrough and intended for dry spaces, with a corresponding
cross-seconal area and number of wires. Amphenol Aquarius
Ecomate connectors have been factory-installed to the end of
the wires. (Figure 11)
[Figure 11] Amphenol Ecomate Aquarius
connector pair

17
REMORAN™ WAVE 3
A 22-mm hole should be drilled in the desired locaon in the transom of
the boat for the feedthrough of the cables (Figure 12). Ensure that the
2-metre generator cable reaches the feedthrough without becoming
excessively taut, allowing the outboard unit to turn freely. Seal the
feedthrough properly with the O-ring supplied with the connector and
a sealant suitable for the purpose. Aer that, screw the connector into
place (Figures 13 and 14).
The length of the dry area cable supplied in the sales package is 2
metres. The cable is connected to the charging unit in accordance with
the numbering on the wires (see secon 4.4.4 Connecng the cables
to the charger).
4.4.3 Using extended generator cables
The outboard unit’s integrated cable is a special product and designed
to withstand marine condions. In addion, the connector is factory-
installed using a waterproof method. We do not recommend that you
modify this cable. If you need a longer outboard unit cable, please
contact the manufacturer. If the cable is too long, you should coil it up
ghtly to prevent it from becoming tangled with the ropes of the boat
etc.
Generator cable. The cables inside the boat can be extended by using
methods typically used in the boat’s low-voltage electrical connecons.
We do not recommend detaching the feedthrough connector from the
original cable; instead, the extension should be carried out at the end
of the original cable. When making the extension, ensure that the new
cable has the same number of wires and the same cross-seconal area
than the original cable. Also note the numbering of the cable wires
and connect the numbered wires of the cable to the corresponding
numbered screw terminals of the charger.

4.4.4 Connecting the generator cables to the
charger
Three wires of the generator cable are numbered and one wire is
the protecve earth (green-yellow). The numbered wires should be
connected to the corresponding numbered screw terminals of the
generator connecon of the charger (Figure 15). The protecve earth
wire has been connected to the hydrogenerator’s aluminium frame
structure. If the operator so wishes, the protecve earth wire can be
connected to the boat’s earth potenal to prevent corrosion to the
generator's mechanical parts. If the wire is not connected, it should be
taped or, if needed, cut. Using the wire for any other purpose is strictly
forbidden.
4.4.5 Connecting the charging wires to the
charger
The charging wires (posive and negave) to be connected to the
baery should be selected so that the maximum charging current
(25A) does not cause signicant power loss (heat). The minimum cross-
seconal area of the wire is 6 mm2, but we recommend a 10 mm2 wire
to ensure opmal charging. The sales package does not include the
wires but they can be ordered from our webstore. Also do not exceed
the wire length of 3 metres.
The red charging wire (+ posive) should always be equipped with
a 40 A circuit breaker (between the charger and the baery). Install
the circuit breaker as close to the baery as possible (max. 30 cm).
If you do not have a circuit breaker available, you can order one
from our web store. There is no circuit breaker inside the charger.
!
[Figure 15] The cables are
numbered (1, 2, 3) and
should be connected to the
corresponding apertures.
[Figure 16] Carefully connect
the charging wires to the
appropriate apertures with
the + and - wires in their
appropriate locaons.

19
REMORAN™ WAVE 3
To ensure uninterrupted operaon of the product, install a clamp-on
ferrite lter on the posive charging wire (Figure 17). The ferrite lter
is included in the sales package and should be installed as close to
the charger as possible. When closing the plasc body of the ferrite
around the wire, you should hear a click when the two pieces interlock.
This ensures that the pieces are properly connected. If needed, they
can be reopened by turning the clip on the side of the ferrite.
When stripping the generator cable and the charging wire, use
sucient lengths in order to avoid short-circuits: The stripping length
of the generator cable (Figure 18) and the stripping length of the
charging wires (Figure 19). Roll the copper threads of the stripped
cables into smooth bundles before inserng them into the charging
unit. The threads must not bristle and touch adjacent screw terminals
or wires!

4.4.6 Circuit diagram
When connecng the hydrogenerator (Figure 20), rst connect the
wires of the generator (Figure 21). A rechargeable baery or baery
pack may be connected only aer that. The connecons must always
be performed on an unenergised product
(the generator must not run). All connecons must be performed
carefully and in compliance with the electrical safety regulaons.
[Figure 20] Connecon illustraon
[Figure 21] The generator wires are connect-
ed to the chargers so that the wire numbers
match the numbering of the screw terminals
in the charger.
