Precaution StatementsFollow these safety, servicing and ESD precautions to prevent damage and to protect against potential hazards such aselectrical shock.1-1 Safety Precautions1. Be sure that all built-in protective devices arereplaced. Restore any missing protective shields.2. When reinstalling the chassis and its assemblies, besure to restore all protective devices, includingnonmetallic control knobs and compartmentcovers.3. Make sure there are no cabinet openings throughwhich people - particularly children - might insertfingers and contact dangerous voltages. Suchopenings include excessively wide cabinetventilation slots and improperly fitted covers anddrawers.4. Design Alteration Warning:Never alter or add to the mechanical or electricaldesign of the SECR. Unauthorized alterationsmight create a safety hazard. Also, any designchanges or additions will void the manufacturer’swarranty.5. Components, parts and wiring that appear to haveoverheated or that are otherwise damaged shouldbe replaced with parts that meet the originalspecifications. Always determine the cause ofdamage or over- heating, and correct any potentialhazards.6. Observe the original lead dress, especially near thefollowing areas: sharp edges, and especially theAC and high voltage supplies. Always inspect forpinched, out-of-place, or frayed wiring. Do notchange the spacing between components and theprinted circuit board. Check the AC power cordfor damage. Make sure that leads and componentsdo not touch thermally hot parts.7. Product Safety Notice:Some electrical and mechanical parts have specialsafety-related characteristics that might not beobvious from visual inspection. These safetyfeatures and the protection they give might be lostif the replacement component differs from theoriginal - even if the replacement is rated forhigher voltage, wattage, etc.Components that are critical for safety areindicated in the circuit diagram by shading, () or(). Use replacement components that have thesame ratings, especially for flame resistance anddielectric strength specifications. A replacementpart that does not have the same safetycharacteristics as the original might create shock,fire or other hazards.CAUTIONDanger of explosion if battery is incorrectly replaced.Replace only with the same or equivalent type recommendedby the manufacturer.Dispose used batteries according to the manufacturer’sinstructions.ATTENTIONll y a danger d’explosion s’il y a remplacementincorrect de la batterie.Remplacer uniquement avec une batterie du même typeou d’un type équivalent recommandé par leconstructeur.Mettre au rebut les batteries usagées conformément auxinstructions du fabricant.SAM4s ER-900 Series Operator's & Programming Manual v.1.3 3
