9.0 LITHIUM BATTERY REPLACEMENTThe <strong>Class</strong> <strong>3200</strong> meter has a lithium coin cell battery, which is used to retain thecontents of SRAM and the RTC during power outages. The battery’s life expectancy isgreater than 5 years.Nominal Working VoltageNominal Current CapacityCell ChemicalOperating Temperature RangeManufacturerManufacturer’s Part Number3 Vdc Output225 mAHrManganese Dioxide Lithium-30 to +60 Degrees CelsiusPanasonicCR2032Table 1. Battery specifications at 25 degrees Celsius.WARNINGReplace battery with Panasonic part number CR2032 only. Use of anotherbattery may present a risk of fire or explosion. See owner’s manual for safetyinstructions.The battery cell is mounted in a coin cell holder on the upper right side of the mainpower board. The internal unit firmware will set a flag to indicate the low batterycondition. When the unit data is next downloaded, the monitoring facility will be alertedof the low battery condition and will schedule a service call.+ –BATTERYM33197Fig. 20. Lithium Battery Cell.CAUTIONBattery may explode if mistreated. Do Not recharge, disassemble, or disposeof in fire.62-0390-02 32
9.0 LITHIUM BATTERY REPLACEMENT(CONTINUED)Use the following procedure to replace the lithium battery cell.CAUTIONThe battery is not completely discharged; therefore, DO NOT short theterminals on the battery with any conductive material.CAUTIONInternal circuit card components are extremely sensitive to electrostaticdischarge. Be careful not to touch internal circuitry prior to discharging anystatic buildup on your person. T o discharge yourself, touch a grounded metalobject such as conduit or a metal enclosure interior.1. Disconnect power from the meter at the unit external circuit breaker.2. Remove the battery from its holder and place on a non-conductive surface.3.
