IMPORTANT SAFETY WARNINGS
FOR AUTOMOTIVE 12 VOLT USE ONLY, NOT TO BE USED WITH DRY CELL BATTERIES.
To avoid any personal injury, please read the following safety instructions. This battery charger is not intended for use by young children or infirm persons
without supervision.
1. During the charging process, do not use a naked flame near a battery.
Batteries generate explosive gasses during the charging process that
may explode.
2. Never smoke or light cigarettes near a battery.
3. Do not place tools on top of a battery or allow tools to fall on the battery
to prevent the chance of a short circuit and sparks.
4. Always wear eye protection when charging a battery.
5. Ensure charging and testing is conducted in a well ventilated area.
6. Ensure the chargers ventilation holes are not obstructed. Inadequate
ventilation may over-heat the charger and cause in-efficient operation.
7. This battery charger is not intended for outdoor operation.
Do not expose it to moisture or extreme weather conditions.
8. If skin or clothing comes in contact with battery acid, flush the affected
area immediately with water. Seek medical attention if necessary.
NOTE:
The warnings, cautions and instructions detailed in this manual cannot cover all possible conditions and situations that may occur.
Common sense and caution are factors which cannot be built into this product and must be supplied by the operator.

INSTALLATION INSTRUCTIONS
• Locate the charger in a suitable dry area in the vehicle or caravan.
• Secure the charger using the mounting tabs on the unit.
• Connect the input terminal on the rear of the charger using suitable cable
to the main starting battery of the vehicle (see specification table on
next page), it is recommended to place a circuit breaker (30A minimum,
not supplied) in the main positive lead as close as possible to the starting
battery.
• Connect the auxiliary battery to the output terminal of the charger, ensure
the correct size cable is used to prevent any voltage drop (see specification
table on next page).
• It is recommended to place a circuit breaker (30A minimum, not supplied) in
the auxiliary positive lead as close as possible to the auxiliary battery.
• Secure the negative wire to the common negative terminal and secure to a
metal (unmoving) part of the vehicle, it is preferable to connect this directly
to the negative terminal of both batteries.
• The TDR02010 will work with even the newest computer controlled
alternators, for installation into vehicles with variable voltage alternators,
negative must be connected to vehicle chassis.
• If connecting a solar panel connect the positive from the panel to the
solar input terminal and the negative of the panel to the negative terminal.
• There is no need for an external regulator the DC/DC has a built in
MPPT solar regulator.
• Check all connections are tight.
Once correctly installed the TDR02010 is a simple set and forget dual battery
solution.
Start the vehicle and let it idle, the charger will recognize that there is charge being
applied to the main starting battery. Once the main starting battery has reached
13.1V the charger will automatically begin to charge.
The charger will continue to operate even after the vehicle has been switched off,
however once the main start battery falls below 11.9V the charger will automatically
shut down.
The TDR02010 will prioritize the vehicle input over the solar input so while the
battery voltage is above 11.9V it will continue to charge, however once the main
battery has reached 11.9V and the charger switches off it will look for a solar
input.
If the solar input is above 13V then the green LED on the display will illuminate to
indicate that the TDR02010 is now using the solar input to charge the auxiliary
battery.
Once the solar input goes under 12V the charger will turn off completely.

INTEGRATED LED DISPLAY & WIRING DIAGRAM
The TDR02010 uses an integrated LED display for easy reference of your
auxiliary battery state of charge and indicator lights.
These functions include;
• Solar (green LED)
• Reverse polarity (orange LED including alarm)
• Faulty battery (red LED)

REVERSE WARNING
BATTERY ERROR
Solar Panel
As your auxiliary battery charges, its state of charge is reflected by the Thunder
logo illuminating in 10% increments. A percentage charge is also shown in green.
This percentage charge will be affected by loads that are attached to the auxiliary
battery. The percentage charge of the auxiliary battery is most accurate when
there is no load being drawn.
