SA-WMSP87/WMSP87E SECTION 1 DIAGRAMS
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this, the necessary note is printed in each block.)
Note on Printed Wiring Boards: � X : parts extracted from the component side. � Y : parts extracted from the conductor side. � : Pattern from the side which enables seeing. Note on Schematic Diagrams: � All capacitors are in µF unless otherwise noted. (p: pF) 50 WV or less are not indicated except for electrolytics and tantalums. � 2 : nonflammable resistor. � 5 : fusible resistor. � All resistors are in � and 1/4 W or less unless otherwise specified. � C : panel designation. Note: The components identified by mark 0 or dotted line with mark 0 are critical for safety. Replace only with part number specified. Note: Les composants identifiés par une marque 0 sont critiques pour la sécurité. Ne les remplacer que par une piéce por tant le numéro spécifié.
