Installation

ATTENTION

• Do not expose the DC/DC booster to rain or snow.
• Do not use the DC/DC booster if it has received a sharp blow, been dropped, has cracks or openings in the case, or is damaged in any other way.
• Do not install the booster near a heat source.
• This booster should not be installed in an airtight or poorly ventilated area.

PRECAUTION

• Do not attempt to open the DC/DC booster. There are no user serviceable parts except for user replaceable fuses.
• Do not use the DC/DC booster with damaged cables.
• It is strictly forbidden to disassemble the booster and/or modify the housing in any way.

This booster is suitable for use in recreational and commercial vehicles.

Leave a free space of at least 5 cm / 2 inches around the booster for good ventilation.

Install the booster in a vertical position to create optimal ventilation. Note that the wiring is located at the bottom of the booster.

All electrical connections to and from the booster must remain accessible at all times.

The booster must be properly and securely fastened.

This appliance is not a toy and must be kept out of the reach of children.

Connections

ATTENTION

• To prevent overheating, make sure the connections are properly tightened.

The installation to which the booster is connected must comply with the standards in force in the country of use.

The output batteries must be connected to the booster before switching on the power.

This equipment complies with the standards in force concerning interference emitted and interference from external sources.

With regard to electromagnetic interference, make sure that other equipment used is compatible with this device to avoid irreversible damage.

Serial number (S/N)
The serial number is available on the grey label stuck on the top of the booster.

Choose the load curve

WARNING

• It is important to choose the correct charging curve, adapted to the battery technology. A wrong choice can cause irreversible damage. In particular, there is a risk of overheating and harmful gases in the event of overvoltage on the battery.

The LITHIUM charging cycle is only compatible with LiFePo4 batteries with integrated BMS (Battery Management System).

Maintenance

If necessary, the fuses must be replaced by identical products.

This booster cannot be disassembled and the electronic board is inaccessible.

Therefore, with the exception of the fuses, all on-site maintenance is prohibited.

Battery precautions

DANGER

• Disconnect the DC power supply before servicing, cleaning or working on circuits connected to the DC/DC booster.
• Once disconnected, isolate the battery connection terminals.

Chemical and gas risks

ATTENTION

• It is important to ensure that the area around the batteries is well ventilated. The gas produced by the batteries can be explosive. Protect the eyes of all persons in the vicinity of the batteries. Ensure adequate ventilation to avoid accumulation of harmful and/or dangerous gases. Do not smoke, use open flames or cause sparks near the batteries at any time.
• It is important to make sure that the battery voltage matches the output voltage of the DC/DC booster.
• It is important to make sure that no corrosive products come into contact with the eyes or skin when working on the batteries.
• Always remove metal objects from hands, wrists and neck, such as rings, bracelets, watches or necklaces.
• Always work with grounded battery. If necessary, the battery ground connections should be made last.

PRODUCT PRESENTATION

PACKAGE CONTENTS

DIMENSIONS

BOOSTER ATTACHMENT

Overview of the booster

DANGER

• Before connecting a battery, it is necessary to switch off the power supply.
  

Connectors
The DC/DC booster is supplied with removable connectors for easy installation.

ATTENTION

After plugging in the power connector, it must be locked to the DC/DC booster by tightening its fastening screws completely.

The cable cross section to be used depends on the distance between the DC/DC booster and the equipment:

Equipment| Cable cross-section with booster 12.25/18| Cable cross-section with booster 12.40/18
---|---|---
B1 and B2 if Lg < 3m| 6 mm²| 10 mm²

FRIDGE if Lg > 3m| 10 mm²| 10 mm²

D+ connector

| Rep.| Designation
---|---|---
| D +| Alternator signal

Cable cross-section: max. 1.0 mm².

The D+ signal allows the DC/DC booster to operate at the same time as the vehicle engine:

• Booster ON as soon as D+ = 12V
  

• Booster OFF as soon as D+ = NC or 0V

Adjusting the selectors

• Selectors 1 and 2 are used to choose the type of charge in relation to the type of battery.
• Selector 3 is used to choose the type of refrigerator.
• Selector 4 allows autonomous operation without a D+ signal.

ATTENTION
The «ON» position of the dipswitch is towards the rear side of the DC/DC booster housing.

Using

WARNING
Caution, important risks of overheating of the batteries, and gaseous emissions harmful to health, in case of charging cycle not suitable for battery technology. In case of uncertainty, contact the battery manufacturer.

Operation with D+
If the D+ signal is used, the DC/DC booster operates automatically when the vehicle engine is running.
The auxiliary battery is then recharged when the main battery is full and the fridge is powered to produce cold.

Operation without D+ signal
The DC/DC booster works when the B1 battery is properly charged. The auxiliary battery is then recharged when the main battery is full and the fridge is powered to produce cold.

Operation of the Fridge output

When the motor is running and/or the motor battery B1 is relatively charged, the Fridge output is directly powered by B1.

When the motor is stopped and/or the motor battery B1 relatively little charged, the fridge output is switched off or supplied by B2 according to the setting of Dipswitch N°3 :

• fridge output cut off in absorption position ,

• fridge output powered by B2 in compression position
