(6) Check air cleaner

The air cleaner

(Sect. 1-1, Fig. 3, item 7)

is a “dry” type. Be sure there are no papers, tapes, or

other material covering the air inlet area.

C. Installing Output Cables

Units are generally shipped without generator set-to-aircraft cables.

(1) Three-phase, AC output cable assembly installation

The AC output terminal panel access cover is located on the right side, just to the right of the en-
gine control panel

(see Fig. 1).

(a) Remove output terminal panel access cover.

(b) Loosen cable horn clamps and and insert the loose ends of the cable assemblies through the
cable horns. Route to output terminal panel.

NOTE: Conductor size recommended for AC output is 2/0 size. Use No. 12 size for control (E and F
terminals). Large cables (A, B, C, N) should be equipped with terminals having at least a 3/8-inch diameter
mounting hole. Mounting hole in small leads (E and F) should be at least 1/4-inch diameter.

(c) Each terminal stud is identified by an identification plate. Each cable should be identified by a
band-type marker. Connect cable “A” to terminal “A”, “B” to “B”, etc. Connect one cable assembly
to the upper row of terminals, and connect the other cable assembly to the lower row of terminals.

(d) Tighten clamp screws securely, but avoid damage to cable insulation.

(e) Install terminal panel access cover which was removed in step (a) above.
