7. SeeFigure4foranexampleofacompletedleftsidemountedCMAinstallation.
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.
