Installation Overview- Printable

Product Description
STC SA02601CH authorizes the modification of Univair (ERCO) 415-C, -CD, -D, - E, -G, F-1, F-1A aircraft to incorporate the installation of a high current battery master relay and low current control circuit.

This installation is accomplished through the addition of a high current master relay attached to the battery box, which reuses much of the existing factory installed wiring.

There are two methods developed and approved to accomplish this modification.

  • Method 1 – Provide a battery box mounted master relay controlled by the contacts of the existing AN3023 - 2 battery master switch.
  • Method 2 – Provide a battery box mounted master relay controlled by the contacts of a new AN3027-2 or MS35059-22 battery master switch at its current location or instrument panel mounted.
    Material is supplied to accomplish either installation method.
