Power supply
Invia Liberty pump is operable while connected to the electrical power supply or by an internal recharge-
able lithium-ion battery. While in use and connected to the electrical power supply, the battery is re-char-
ged.
The charge on the battery is dependent upon the run-time of the pump. The run time refers to
the effective operation of the motor. Invia Liberty pump motor only turns on when the measured pressure
is lower than the set pressure.
Under typical operating conditions, the battery run-time generally exceeds 14 hours. Battery run-time is
influenced by the size of the wound, the air leakage in the system and the set pressure. If there is a
leakage in the system, the pump motor will run more often, which will reduce the battery run-time.
USB port
Additional equipment connected to medical electrical equipment must comply with the respective IEC or
ISO standards (e.g. IEC 60950 for data processing equipment).
Furthermore all configurations shall comply with the requirements for medical electrical systems (see IEC
60601-1-1 or clause 16 of the 3Ed. of IEC 60601-1, respectively). Anyone connecting additional equip-
ment to medical electrical equipment configures a medical system and is therefore responsible that the
system complies with the requirements for medical electrical systems. Attention is drawn to the fact that
local laws take priority over the above mentioned requirements. If in doubt, consult your local representa-
tive or the Medela customer service department.
CAUTIONS
Before you charge the device, please check that your local power supply is the same
as the voltage given on the specification plate.
