PRODUCT OVERVIEW

IDC25X

INSTALLATION

MOUNTING

• IDC25X’s IP68 & IP69K tough & rugged design allows for the unit to be mounted where best suits the application. IDC25X entire PCB is potted using a high-quality thermal compound inside the aluminium extrusion; this ensures IDC25X is impervious to vibration, dust, moisture and extreme temperatures. Though tough, it is advisable however to keep the charger as far away from exhaust, turbos, or any other high temperature components to ensure improved performance.

WIRING

• To make reliable and durable electrical connections, battery cables will need to be made to the correct length. Reducing the wires’ or cables’ lengths properly will help to avoid unexpected voltage drops and noise. Cable lugs should be crimped and insulated to the cable before connection to the brass posts and spade terminals.

Minimal cable size for wiring up to 12m

Please increase the cable size for cables beyond 12m length as required. Contact Technical Support for assistance on 1800 422 422.

1. Disconnect the negative battery cable (Earth) from the vehicle’s starting battery or disconnect power to the trailer. Note: To prevent the loss of vehicles electronic memories, radio pre-sets & security codes, it is recommended that an “Electrical System Memory Protector” be used.

2. Connect the Auxiliary Battery positive (+) terminal to the IDC25X auxiliary battery output post. Fit at a fuse (50A for IDC25X) to the cable as close as possible to the Auxiliary Battery positive (+) terminal.

3. Connect the Auxiliary Battery (-) terminal to the IDC25X common ground output post. Alternatively connect both Auxiliary battery negative (-) terminals and IDC25X common ground output post to the vehicle’s chassis ground. After the Auxiliary battery has been connected, check LED indicators. Do not proceed if either there is Output Overvoltage alarm (red LED) or the LEDs do not turn ON.

4. Connect the Starter Battery positive (+) terminal to the IDC25X Alternator Input Post ( ). Fit at a fuse (50A for IDC25X) to the cable as close as possible to the Starter Battery positive (+) terminal.

5. If your vehicle has a fixed voltage or temperature compensating alternator installed, do not make connection to the Ignition Input Blade Terminal.
   If your vehicle has a smart (variable voltage) alternator installed, the Ignition Input Blade Terminal must be connected to the vehicle’s ignition. At 12.2V ALT voltage, the IDC25X will only operate when the vehicle’s ignition is turned on (may take up to 2 minutes to start charging). Fit a 1-2A fuse to the cable as close as possible to the vehicle’s ignition.
   Consult the vehicles manufacture for type of alternator installed in your vehicle.

6. To add 12Vdc solar panels to the system connect the solar panel positive terminal (+) to the IDC25X solar input post ( ). Fit a fuse to the cable as close as possible to the Solar Panel positive (+) terminal (refer to the table below for fuse size).
   NOTE: No solar controller is required with the IDC25X. If using portable solar panels that include a solar controller, the controller will need to be bypassed.
   After the positive has been connected, connect the solar panel negative (-) terminal to the (-) vehicle chassis ground.

7. The LED output terminal provides about 5mA constant current output. It can power an LED panel mount indicator without an external resistor.
   This LED output terminal is not required to be wired into if you do not need an external LED indicator. If an external LED indicator is required, connect the positive (+) terminal of a LED Indicator to the LED input terminal ( L.E.D ).
   Connect the negative terminal of the LED indicator to the vehicle chassis ground.

8. The TEMP1 & TEMP2 input terminals are used to provide temperature compensated battery charging. Attach the provided temperature sensing loom blade terminals to TEMP1 & TEMP2 inputs on IDC25X, the ports are dual polarity allowing the negative and positive to be plugged into either port. The temperature sensing loom is provided with 5m wire, please cut the excess length to minimize voltage drops and noise.

HOW TO SELECT BATTERY CHEMISTY

IDC25X allows you to select the select the appropriate charge setting for your auxiliary battery.

To change the battery type, hold and press the Mode Button ( ) for about 3 seconds. When the Charge LED turns OFF and the Battery Type LED will begin to flash, then release Mode button. After which, Mode Button ( ) can be short pressed to select the Battery Type. When the Battery Type LED is in the correct Battery Chemistry for about 3 seconds, then that Battery Type chemistry is deemed selected.
To confirm you have selected the correct battery chemistry, press the Mode button.

OUTPUT OVERRIDE
If Auxiliary battery has been heavily discharged, hold and press the Mode button ( ) for about 10 seconds. When all Battery Type LEDS light up simultaneously, let go of the Mode Button. This will cause IDC25X to commence charging.

FREQUENTLY ASKED QUESTIONS

Q. Is the IDC25X waterproof?|
A. The IDC25X was designed and engineered to the stringent ingress protection rating of IP68 & IP69K. This allows the IDC25X to meet the toughest of challenges whether that be river crossings, engine bay washing or direct high pressure washing of the unit.

Q. Why do the positive cables from the batteries need to be fused?
A. High-Capacity batteries can produce large amounts of power and are capable of melting cable insulation and catching fire in the case of a short circuit. Each positive (+) cable connected to the battery must be protected by a fuse located in close proximity to the battery.

Q. Is the IDC25X safe to use with modern ‘electronic’ vehicles?
A. The IDC25X has been designed to work with all vehicles, including new vehicles with EFI and computer management systems. The charger utilizes sophisticated electronics that ensures complete safety for you and your vehicle.

Q. How do I know if the battery is charged?
A. Refer to diagram “LED BATTERY CHARGE STATUS INDICATORS” on page 13 to identify when the IDC25X is indicating battery charging is complete.

Q. I have connected the IDC25X properly but the power LED “ come on?
A. Check the cable size. The IDC25X is designed to power on and charge from an input source as little as 9V. If small size cables are used for wiring, the voltage might drop below 9V when IDC25X is attempting to start up. Please refer to Installation  wiring section for recommended cable size.

Q. I have connected the IDC25X to solar   and alternator inputs  but LEDs do not come on?
A. In some cases batteries can be discharged to the point where they have very little or no voltage. This can occur if a small amount of power is used for a long time, for example a map reading light is left on for a week or more. The IDC25X is designed to charge an auxiliary battery from as little as 2 Volts. Refer to Page 13 Output Override for detailed instruction.

Q. Why does the IDC25X indicate the battery is fully charged straight away?
A. There are three possible reasons why the IDC25X indicated the battery is fully charged.

1. The battery is fully charged.
2. The battery has taken a surface charge.
3. The battery has a faulty cell.

Q. What is a “Surface Charge”?
A. Batteries unused or left discharged for some time build up a resistance to being recharged. When the charger is first connected, these batteries will take a surface charge, and the IDC25X LED’s will indicate the auxiliary battery is fully charged within a short period of time. The battery however is not fully charged. The charger is voltage sensitive and cannot differentiate between a surface charge and a fully charged battery. After a few hours, the battery may start to accept some charge but most batteries with this condition may not recover.

Q. What is a Faulty Cell?
A. 12 Volt batteries contain 6 cells, and one faulty cell is enough to ruin your battery.
If after twelve hours of charging your battery is still accepting charge, you should test the cells using a hydrometer. If one reading is lower than the rest, it indicates a faulty cell. It is pointless to continue charging; the battery needs replacing.

Q. Why is there no output at the IDC25X’s auxiliary battery output?
A. The IDC25X incorporates short circuit protection that makes it much safer For this reason, the IDC25X will only output power when properly connected  to a battery. To check if the IDC25X is functioning, follow the instructions to connect and operate the charger as normal on a flat battery. While the battery is charging measure the battery voltage with a volt or multi-meter. Charging can be confirmed if the voltage is increasing (within the voltage parameters set out in the specifications).
