Product Information
Full details
The Facom DX.8-12A is an essential protective tool for professional mechanics and automotive technicians who need to safeguard sensitive vehicle electronics during maintenance. By neutralizing voltage spikes caused by welding, high-draw power tools, or parallel battery connections, it prevents costly damage to onboard control units. While it offers robust protection for 12V systems, users should note it is designed specifically for standard automotive electrical environments and requires manual connection to battery terminals.

FAQs
Can I use the DX.8-12A on a 24V truck system?
No, this specific model is designed exclusively for 12V systems.
Do I need to leave this connected while the engine is running?
The device is primarily intended to protect sensitive electronics while performing external work like welding or using power tools; it is not a permanent vehicle accessory.
Does this device require a battery to function?
It can be used with a battery present, or connected in place of a battery if the battery has been removed from the vehicle.
Will it protect my stereo system?
It is designed to protect the vehicle's electronic control units (ECUs); while it filters surges, it is not specifically a noise filter for audio equipment.
How do I know if the device is active?
The device acts as a passive surge limiter; as long as it is connected to the terminals, it is actively working to clamp voltage spikes.
Troubleshooting
Unit does not seem to engage
Ensure both battery clips are firmly attached to clean, paint-free metal contacts on the terminal or lead.
Intermittent electrical behavior during work
Check the 300 mm cable for potential damage or loose connections and ensure the unit is not resting against hot engine components.

Setup, Compatibility & Care
To set up the Facom DX.8-12A, ensure the vehicle ignition is turned off before connecting the clips to the battery terminals. If the primary battery has been removed from the vehicle, you can connect the clips directly in place of the battery terminals to maintain a protective circuit. Always verify that the connection is secure and the clips are making full contact with the terminals. For care, keep the unit away from extreme moisture or direct contact with harsh chemical solvents. Inspect the cable insulation periodically for signs of fraying or cracking to ensure the protective shielding remains effective.
