Operating Instructions
The Ferve F-970 offers both battery charging and jump starting functionalities.
Battery Charging
- Prepare Battery: Ensure the battery terminals are clean and free of corrosion. If charging a lead-acid battery with removable caps, check electrolyte levels and top up with distilled water if necessary.
- Connect Clamps:
- Connect the red (positive, +) clamp to the positive (+) terminal of the battery.
- Connect the black (negative, -) clamp to the negative (-) terminal of the battery. If the battery is in a vehicle, connect the black clamp to a metal part of the vehicle chassis away from the battery and fuel line.
- Select Voltage: On the charger's control panel, select the appropriate voltage (12V or 24V) corresponding to your battery.
- Connect Power: Plug the charger's power cord into a suitable mains power outlet.
- Start Charging: Turn on the charger. The unit will begin charging at a current of 70A for 12V batteries or 55A for 24V batteries. Monitor the charging process.
- Disconnect: Once charging is complete, first turn off the charger, then unplug it from the mains. Finally, disconnect the black (negative) clamp, followed by the red (positive) clamp.
Jump Start Function (450A)
Use the jump start function only when the vehicle's battery is severely discharged and needs immediate assistance to start the engine.
- Vehicle Off: Ensure the vehicle's ignition is off and all accessories are turned off.
- Connect Clamps:
- Connect the red (positive, +) clamp to the positive (+) terminal of the vehicle's discharged battery.
- Connect the black (negative, -) clamp to a solid, unpainted metal part of the vehicle's engine block or chassis, away from the battery and moving parts.
- Connect Power: Plug the charger's power cord into a suitable mains power outlet.
- Activate Jump Start: Select the jump start mode on the charger (refer to the control panel markings).
- Start Vehicle: Attempt to start the vehicle's engine. Do not crank for more than 5 seconds. If the vehicle does not start, wait at least 1 minute before trying again.
- Disconnect: Once the vehicle starts, immediately turn off the jump start function on the charger. Then, unplug the charger from the mains. Disconnect the black (negative) clamp first, followed by the red (positive) clamp.
