Installation & Usage Notes

For optimal performance and safety, please consider the following general guidelines:

• Mount the converter vertically on a non-flammable surface, ensuring the power terminals face downwards.
• Allow for a minimum clearance of 10 cm (approximately 4 inches) above and below the product to ensure adequate cooling.
• Position the converter close to the battery, but never directly above it, to prevent potential damage from battery gassing.
• Always ensure correct polarity when connecting cables. Reverse polarity can damage the device and is not repairable.
• The input positive connection should be protected by an appropriately rated fuse (refer to the manufacturer's manual for specific recommendations).
• The adjustable output voltage can be set using a potentiometer; always connect a small load when adjusting the voltage for accurate readings.
• For detailed installation instructions, wiring diagrams, and fuse recommendations, always consult the official Victron Energy manual for this specific model.
