Notes: Before installation the user shall determine the suitability of the product to ensure correct application. A large spark can sometimes
be generated during the connection sequence due to the current required to charge the internal capacitors inside the reducer.
The following connection sequence is to be followed: Ground (Black), Input (White), Output (Red), Control (Blue).
1. Disconnect the battery supply.
2. Choose a mounting position. It is recommended to mount the unit inside the vehicle as the unit is not waterproof.
Select a position with good ventilation where air can pass freely around the unit. Avoid locations such as fuel lines or
where external heat is produced e.g. exhaust system or where the batteries are located.
3. Ensure the unit is protected from water spray and other sources of contamination e.g. oil, grease and dust.
4.
NOTE: A large spark can sometimes be generated during connection, due to the current required to charge the capacitors in the charger.
