 Installation procedure

 -Install the backshell on the wires before you connect them to the connector.
 -Screw the backshell on the connector.
 -Tighten the backshell with pliers UTICA 529 or equivalent.
 ____
NOTE : To make the tightening of the backshell easer you can use a tightening support SOURIAU 580030 or equivalent.
 -If necessary, safety the connector (ref 20-51-12).
 -On metal backshell install a protective pad E0080-CP1 or NSA935404 between the backshell and the bundle.
 -Attach the bundle to the backshell with a cable tie NSA935401.
