7. SeeFigure4foranexampleofacompletedleftsidemountedCMAinstallation.

Cables entering CMA should

have a small amount of slack

to avoid cable strain when

CMA is extended.

NOTE: Do not store excess

cable slack inside the CMA.

The cable may protrude

through the CMA causing

binding and potentially

damaging the cable.
