Compatibility & Fitment

Installation Tips

  • Disconnect all power to the system before installation.
  • A heat sink is recommended for loads approaching the 40A rating to ensure proper heat dissipation.

  • Verify that the wire gauge used is appropriate for the electrical load.
  • Confirm input and output connections are correct before applying power.
