(1) These assemblies are ESD sensitive, ESD precautions shall be observed.
(2) These assemblies must be clean and free from flux and all contaminants. Use of no clean flux is not acceptable.
(3) These assemblies must comply with workmanship standards IPC−A−610 Class 2.
(4) C9 can be installed by the customer if using long cables (inductive load)
(5) Place shunts as follows (Jumper pin orientation: pin 1: top (toward RD), pin 2: center, pin 3−bottom). Place shunts on J5, J6, J7−1/2 (LED);
J9−2/3 (LOW); J8−2 (optional)
