NOTES OF SCHEMATIC DIAGRAM
Safety precautions The Components identified by the symbol are critical for safety. For continued safety, replace safety critical components only with manufacturer's recommended parts. 1. Units of components on theschematic diagram Unless otherwise specified. 1) All resistance values are in ohm. 1/6 W, 1/8 W (refer to parts list). Chip resistors are 1/16 W. K: KΩ (1000Ω), M: MΩ (1000KΩ) 2) All capacitance values are in µF, (P: PF). 3) All inductance values are in µH, (m: mH). 4) All diodes are 1SS133, MA165 or 1N4148M (refer to parts list). Note: The Parts Number, value and rated voltage etc. in the SchematicDiagram are for references only. When replacing the parts, refer to the Parts List. 2. Indications of control voltage AUX : Active at high. AUX or AUX(L) : Active at low.
