Torque Settings
- 150A connector: 3Nm
- 80A / 40A connectors: 1.8Nm
- 25A connectors: 0.8Nm
- Tighten all unused clamps to avoid vibration noise. In high-vibration builds, check torque as part of regular maintenance.
Recommended Tool: EGON recommends using a precision torque screwdriver, such as the Precision Torque Screwdriver available from EGON, to correctly tighten the contacts on the circuit board.
Fuse Handling
- Fuses are designed to fit tightly to prevent voltage drop and overheating. Do not bend or loosen fuse holders.
- If a fuse becomes loose, gently pinch the connector with pliers before reinserting.
- Pay particular attention to fuse fitment at P9 (DC/DC charger).
Cable sizes (max) for connectors:
150A = 50mm², 80A = 16mm², 25A = 4,59MM²
