Victron Lynx Power In wiring diagram

The Lynx Power In is an unfused positive/negative distribution module with four connection pairs and a ground connection. Victron's M8/M10 manual covers both generations. This catalog's generic model name does not encode a purchase part number; confirm the actual interconnection size before joining modules.

M10 identifies the enlarged module-to-module joints. It does not mean every internal branch fastener is M10: the manual's introduction and DC-wire instructions specify M8 cable connections. Its later drawing also labels an M10 negative connection, so inspect the supplied hardware before choosing all lugs from the cover name alone.

All 1+ through 4+ points join one positive busbar; all 1− through 4− points join one negative busbar. They are connection positions, not independently switched or regulated outputs. Batteries, chargers or loads can use these positions as appropriate to the system layout.

If the assembly includes a battery shunt or Lynx BMS, battery connections belong on its battery side and every load/charger return belongs on its system side. Putting a charging return directly on the battery-side negative rail bypasses measurement even when the drawing appears electrically connected.

There are no onboard fuses. Printed page 8 requires externally fused connections for attached loads, chargers and batteries. A plain Power In is not a Lynx Distributor and does not become one merely by fitting a fuse somewhere on its end busbar.

The module is rated 1000 A continuous, but that does not assign 1000 A to every cable or certify an equal 250 A allocation among four branches. Review the actual simultaneous current, cable ratings, source-side protection, fuse voltage and available fault current. The least-rated part of the complete Lynx assembly remains a constraint.

Printed pages 10–11 specify 14 N·m for M8, and 33 N·m for M10 joints, reduced to 17 N·m for units with serial numbers before HQ2340XXXX. Apply the correct value to each actual fastener and follow the illustrated lug/washer order. Keep unused busbar ends insulated and secure the assembly using its mounting holes.

The manual places any required system-ground connection after the current-measuring shunt/BMS. The catalog drawing omits that grounding design, external fuse hardware and the mechanical M8/M10 interfaces. Verify those before energising, alongside polarity, protected conductor routing and the final covered assembly.
