2 OPERATING-PRESENTATION-INTERFA ES
2.1 O PERATING PRIN IPLE
The design of the battery charger is based on a high-frequency converter that transforms the DC signal 12V into
regulated and filtered DC signal 24V.
Once the type of battery and type of charge has been selected, operation of the battery charger is entirely automatic
(unless otherwise specified by the supplier or the manufacturer of the batteries). It can remain connected to the
batteries and does not need to be disconnected when starting up an engine (marine application), because it is
equipped with an integrated separator.

5
2.2 O VERVIEW PRESENTATION
The chargers are divided into 2 zones :
•The user interface zone
•The energy conversion zone (all maintenance in this area is forbidden except with CRISTEC authorization, under
penalty of warranty termination)
Fixing of the charger is made by 4 x M5 round head screws (screw head diameter less than 10 mm).

3 INSTALLATION
This paragraph deals with installation of the equipment.
Installation and initial commissioning should be carried out by an electrician or professional installer in accordance
with the standards currently in force (for pleasure boats the applicable international standard is ISO13297).
The installer should familiarize himself with this operating manual and inform users of the instructions for use and the
safety warnings set out in the manual.
3.1 HARGER OVERALL DIMENSIONS
Place the charger vertically, connection downwards. Failure to respect this position may cause a decrease in available
power and a loss of IP level.
A clear area of 150mm all around the charger for proper ventilation and opening of the charger.
Never put anything on the charger.

3.2 W IRING
When connecting or disconnecting a cable, the charger's power supply must be turned off and the batteries
electrically insulated from the charger.
The references for additional cables required for the appliance to operate efficiently are provided in the following
paragraphs : failure to comply with these provisions renders the warranty null and void.
3.2.1 Battery cable
Disconnect batteries before any wiring and junction of the connector.
Please check the compatibility of voltage, current and setting according to the battery type before switching ON the
charger.
hecking of the charge voltage
Before connecting the batteries to the charger, first check their polarity.
Equally check the battery voltage with a calibrated voltmeter. A too low voltage value on some types of batteries
show irreversible damage and impossibility to recharge.
Any damage due to incorrect connections will be excluded from the warranty.
For battery cables up to 3 metres, the cross-section of the battery cables should be at least equal to or greater than
the values provided in the table below:

Input +12V and 0V common 25mm²

The installer should choose the type of cable (H07-VK, MX, etc.) according to the type of application and the applicable
standards. The connection is made by bolting ring terminals to the 3 electrical power studs.

3.2.2 Precautions regarding electromagnetic disturbance generated by the appliance
We recommend a minimum distance of 2m between the charger and any potentially sensitive equipment.
Use shielded cables for all the connections (*). The shielding should be earthed at both the transmitting and the
receiving ends.
Keep cable length and shielding connections to a minimum.
Route cables as close as possible to conductive parts ("loose" cables or loops should be avoided – cables should be
placed against the hull or walls).
Keep power cables separate from battery cables.
Keep power cables separate from control cables (at least 200mm).
The cables should only supply power to this appliance; any deviation to power another appliance is prohibited.
(
*
)
This is a recommendation for installation rather than an obligation. The installing electrician should decide
whether or not to use shielded cable depending on the EMC environment.

3.3 S WIT HES SETTING - ADJUSTMENT - INDI ATORS
3.3.1 Description
The YPOWER chargers are equipped with switches to configure the charger according the battery type and the
application.
1 = ON
0 = OFF
2 charging modes are available :
-The BOOST function enables a faster charge of the batteries. This function is timed controlled (see table here after)
and is automatically switched off when the battery is fully charged : BOOST stops when batteries current < 20% of
charger rated current. The BOOST function can also be disabled by means of a switch (E).
-The REFRESH function enables to apply periodically a voltage step to maintain the battery, to promote its equalization
and prevent from any sulphation. This function is activated by means of a switch (F).
1 = ON
0 = OFF

3.3.3 Temperature compensation
The STP-NEW-2.8 probe enables the compensation of Absorption voltage and
Floating Voltage depending on the ambient temperature of the battery room.
The coefficient used is -3mV/°C/element.

12
3.3.4 Factory setting
The charger's factory settings are:
Sealed type battery (lead sealed)
BOOST in ON position
REFRESH in OFF position
This setting is a compromise for satisfactory recharging of different technologies of batteries :
-Opened classic lead
-Sealed, Gel or AGM
-Spiral sealed
-Lithium Iron Phosphate ( LiFePO4 ) with BMS
To define the charge in function of your battery, please refer to the chart, paragraph : 3.3.2.
RISTE is not liable for any damage caused to the batteries or for inefficient recharging.

13
3.3.5 harging curve
BOOST in ON position
With this setting the YPOWER charger delivers a 5-step charge curve IUoU + automatic weekly recycling (switch F) +
return to automatic BOOST : BOOST, ABSORPTION, FLOATING + REFRESH, REBOOST.
V BOOST : BOOST voltage (see table above)
V FLOAT : FLOATING voltage (see table above : voltage with no BOOST)
T BOOST : BOOST maximum duration (see table above – paragraph 3.3.2)
T ABS : ABSORPTION maximum duration (see table above – paragraph 3.3.2 )
BOOST phase :
Starts up automatically when the charger is turned on if the battery is flat. The current is then at maximum output.
ABSORPTION phase :
Begins when the voltage has reached the maximum BOOST level. The current level starts falling.
These two phases combined last a maximum of TBOOST+TABS (depending on setting). If the current falls below 20% of
rated current, the FLOATING phase automatically kicks in. Duration and current intensity depend on how charged the
battery is.
FLOATING phase :
Starts after TBOOST or if output current has reached 20% of the charger's rated current. The voltage switches to the
FLOATING value and the rated current continues to drop.

14
REFRESH phase :
It is an automatic weekly cycle (Inhibited or not by means of switch F) in order to optimize the battery life duration.
It will occur only after a complete recharge cycle (BOOST, ABSORPTION and FLOATING).The charger will generate
automatically a safe timed voltage step every 7 days whatever the position of BOOST switch.
Phase REBOOST :
Automatic phase consisting in coming back to a BOOST voltage if the DC utilizations require it (i.e. after a complete
recharge cycle BOOST, ABSORPTION and FLOATING if a some DC constant consumptions are detected the charger will
restart a new complete charge cycle including a BOOST phase).
This REBOOST phase will be authorized after measuring certain battery voltage during a determined time.
BOOST in OFF position
With this setting, the YPOWER charger produces a single-stage UI type charge curve. It generates a constant voltage,
supplying the current required by the battery(ies). Recharging time depends on the state of the battery, being longer
than when the BOOST is in the ON position.
3.3.6 Indicators
The following led indicators are visible on the front of the appliance for monitoring.

4 EQUIPMENT MAINTENAN E AND REPAIRS
4.1 O VERVIEW
This paragraph deals with equipment maintenance and repairs. Proper operation of the product and its service life are
dependent on strict compliance with the following recommendations.
4.2 E QUIPMENT MAINTENAN E
Disconnect the battery charger from the DC network and the batteries before starting any maintenance work.
If appliances are in a dusty atmosphere, vacuum-clean them regularly, since dust deposits may adversely affect heat
dissipation.
Check the state of battery charge every 3 months.
Nuts and screws should be tightened annually to ensure efficient operation of the appliance (particularly in rugged
conditions: vibrations, shocks, high variations in temperature etc.).
4.3 E QUIPMENT REPAIRS
Disconnect the battery charger from the DC power network and disconnect the batteries before undertaking any
repairs.
When fuses have blown, only use fuses of the type and size recommended in this manual.
Please contact CRISTEC or their distributor for any other repairs.
Any repair without CRISTEC prior agreement entails an exclusion of warranty.
