NOTES:

N.A. CAUTION: THIS DEVICE IS SUBJECT TO DAMAGE BY STATIC ELECTRICITY. LINCOLN ELECTRIC TO SEE E2454 BEFORE HANDLING.

N.B. SNAP POWER TERMINALS INTO COMPONENT SIDE OF BOARD. N.C. THIS AREA TO BE COVERED ON BOTH SIDES OF BOARD (WHERE

POSSIBLE) WITH SEALANT PRIOR TO ENCAPSULATION.

N.D. INJECT SEALANT ITEM 8 THROUGH THE PC BOARD TO SEAL MODULE LEADS

(16 PLACES), AND ALL COMPONENT LEADS ON THE NONO-COMPONENT SIDE OF THE BOARD, THAT ARE COVERED BY MODULE CASE.

N.E. FEMALE EYELET TO BE AGAINST THE NON-COMPONENT SIDE AS SHOWN EYELET MUST NOT SPIN AFTER CLINCHING.

N.F. SOLDER EYELET SO THAT SOLDER COVERS ENTIRE EYELET AND ALL AROUND EYELET ON COPPER SIDE ONLY.

NO ICICLES OR SOLDER BLOBS PERMITTED.

N.G. AFTER SOLDERING, INSPECT POWER TERMINAL CONNECTIONS TO ENSURE SOLDER HAS PROPERLY WET COMPONENT SIDE PAD ON A MINIMUM OF 3 OF THE 4 LEGS OF THE POWER TERMINAL.

N.H. BAR MUST BE FREE OF ENCAPSULATION MATERIAL ON BOTH SURFACES AROUND MOUNTING HOLES AND ENTIRE LENGTH OF MOUNTING SURFACE. ENCAPSULATION MATERIAL MUST NOT EXTEND BEYOND THE MOUNTING SURFACE PLANE. (2 PLACES)

N.J. DO NOT COAT WITH ENCAPSULATION MATERIAL, TOP AND BOTTOM, .80 +/- .05” DIA.

N.K. PC BOARD HOLES TO BE FREE OF ENCAPSULATION MATERIAL AND SEALANT FOR A DIAMETER OF .50” FOR THE LARGER HOLES, AND .25 FOR THE SMALLER HOLES, BOTH SIDES OF BOARD. (4 PLACES).

N.L. THIS AREA TO BE COVERED ON COMPONENT SIDE OF BOARD WITH SEALANT

PRIOR TO ENCAPSULATION. MATERIAL MUST BE APPLIED FROM TOP TO COMPLETELY FILL TO UNDERSIDE OF DEVICE. THEN APPLY SEALANT AROUND BASE OF DEVICE.

N.M. THIS AREA TO BE COVERED ON OPPOSITE COMPONENT SIDE OF BOARD WITH ITEM 8 PRIOR TO ENCAPSULATION. DO NOT COAT WITH ENCAPSULATION MATERIAL ON THE TOP SURFACES NOR THE THREADS.

N.N. THESE SURFACES MUST BE MAINTAINEDCO-PLANAR WITHIN .010” THROUGH ENTIRE SOLDERING AND SEALING PROCESS.
