DISCHARGING Lights when internal batteries (or auxiliary batteries) are discharging at a rate of 0.25A or greater. Runtime. Approximate runtime under various loads can be computed from the storage capacity (5 A-hr in 12 V mode; 2.5 A-hr in 24 V mode) and the load (main unit and other DBKs). The following Load Wattage vs. Hours graph is for a typical new battery that is fully charged. Charging : In general, lead-acid batteries [and related Gel-Packs] require charging at 120% of drain energy (e.g., the 5 A-hr DBK34A requires a charge equal to or greater than 6 A-hr). Charging times vary; but 4 to 5 hours at 14 V is typical for a completely discharged battery; after which, charging may continue indefinitely. Note that 16 to 18 VDC at the power input is required for optimal charging. CAUTION Voltage applied to a DBK34A must not exceed 30 VDC. Appendix C 977995 Power Options C-7

Environmental Concerns CAUTION DBK34A Gel-Pack batteries contain toxic materials (Pb and H 2 SO 4 ). At the end of the battery life cycle (typically after 5 to 10 years of use), the Gel-Packs must be recycled or properly disposed of. Fuse Replacement DBK34A contains four MINI ATO fuses that can be replaced by the user. Note that you should always check your unit for blown fuses prior to sending it back to the factory for repair. This could save you time and money. The following table indicates the probable reason that a particular fuse may have blown, and includes part numbers and fuse rating. Fuse Rating Probable Cause of Blowing Fuse Replacement Fuse F1 7.5 A Auxiliary Battery overload. 7.5A MINI ATO, LITTLEFUSE# 297-07.5 F2 7.5 A Output overload. 7.5A MINI ATO, LITTLEFUSE# 297-07.5 F3 7.5 A Output overload. 7.5A MINI ATO, LITTLEFUSE# 297-07.5 F4 15 A Input overload. 15A MINI ATO, LITTLEFUSE# 297-015 DBK34A, Fuse Location Reference To replace a fuse: 1. Disconnect the DBK34A from loads and from supply power. 2. Remove the DBK34A’s cover plate. This requires the removal of 4 screws (2 per side). 3. Examine the fuses (F1 through F4) to see which, if any, have blown. Note that you can usually see the blown element through the fuse’s transparent casing. 4. Replace the blown fuse with the appropriate replacement fuse (see preceding table). Note that the fuse value is present on top of the fuse; also, the fuses are color coded as an aid to identification. 5. Replace the DBK34A cover and secure with screws (removed in step 2).
