Figure 8: Power Cartridge Status Gauge
While the Eclipse Power Cartridge allows the concentrator to operate at its full range of capabilities, the primary purpose of
the Power Cartridge is to allow a patient to ambulate while they are moving between stationary power sources. The Eclipse’s
Power Cartridge, like all lithium ion batteries, is susceptible to permanent damage from excessive heat. Exposure to excessive
heat may significantly shorten the service life of the Power Cartridge.
Each Power Cartridge contains multiple temperature sensors to monitor battery cell temperature. The amount of heat the
Power Cartridge can safely endure varies depending on how the Power Cartridge is being used. During discharge, the Eclipse
software will alarm when internal battery cell temperature exceeds 60°C, and will shut the system down if internal battery
cell temperature exceeds 70°C. While the Power Cartridge is charging, software will interrupt charger operation when the
internal battery temperature exceeds 45°C or temperature is less than 0°C . In both of these cases, when internal battery cell
temperature falls within these limits, the Eclipse will resume normal operation. Operation near these temperature limits will
not damage the Power Cartridge, but are in place to ensure that the service life of the Power Cartridge is preserved.
Heat in the Power Cartridge is generated during discharge, and can also be the result of operating the Eclipse in high ambient
temperatures. The amount of internally generated heat varies with the flow setting – higher flows induce greater Power
Cartridge heating. While high ambient temperatures are typically the result of operation on a hot day, running the Eclipse with
inadequate ventilation can also add additional heat. Always ensure that the Eclipse is operated in a well-ventilated space, the
air intake filter is clean, and intake and exhaust vents are unobstructed.
DO NOT tamper with, disassemble, crush or heat the Power Cartridge
above 140° F (60° C). The Power Cartridge may present a risk of fire or
explosion and will void the warranty.
WARNING:
CAUTION
Store the Power Cartridge in a cool, dry place when not in use.
CAUTION
The Eclipse system can only work with a SeQual Power Cartridge. Use
of another Power Cartridge or Battery may damage the unit, present a
risk of fire or explosion and will void the warranty.
CAUTION
DO NOT leave the Eclipse or the Power Cartridge in a vehicle or in the
trunk during a hot or cold day.
