10) To secure the spread plates into the palm beam ends, pull down on the bus wire, and line up the

spread plate screw holes with the leg screw holes. With a 3/16” hex driver, insert a 5/16-

18x1.125 flathead screw (046-06409-00) into spread plate screw hole sans the bus wire. Once

the screw is threaded in and tightened down, remove the bus wire and insert the other counter-

sunk screw in the screw hole that the bus wire previously occupied. You may have to loosen the

other screw a little in order to remove the bus wire.

11) Using the 3/16” hex driver and 5/16-18x2.25 flathead screws (046-06401-00), install the spread

plates (part# 726-06402-01, items 5 & 6) into the back beam ends. (Like spread plate pictured

in Step 5.)

12) Install all the modules into the frame to ensure that their surfaces are flush. Use the

thumbscrews (936-07240-01, S5 thumbscrew kit, 4 per module) to secure the modules to the

box beams. Before installing the 401 module permanently into the frame, attach the talkback

mic bracket (936-07219-01, S5 talkback mic kit) into the middle top screw hole of the SBC panel,

using the screw and insulating washer supplied in the S5 talkback mic kit.

13) After verifying that the control surface is acceptable, tighten all loose screws and bolts in the

frame. Tighten the bolts on the box beam braces only until their lock washers flatten, and no

further. You will have to temporarily remove the modules on each end of the frame to be able to

tighten the box beam braces.

14) Using a ¼” hex driver and 5/16x18x0.375 socket head screws (044-06686-00), install the back

cover braces (item 15, brace 1). Determine the position of the braces by aligning them with the

back cover mounting screw holes. Move the slide nuts in the rear box beam and back beam to

the brace locations, and mount the braces to them.
