Power Supply
CAUTIONS
Before you charge the device, please check that your local power supply is the same
as the voltage given on the specification plate.
Invia Liberty Pump is operable while connected to the electrical power supply or by the
internal re-chargeable lithium-ion battery. While in use and connected to the electrical power
supply, the battery is re-charged.
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 only turns on when the measured
pressure is lower than the set pressure. If the Invia Liberty Pump is running continuously,
Medela suggests a maximum of 4 hours of battery usage before it is necessary to re-charge.
The average run time of the battery exceeds 10 hours. This 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 will run more often which will reduce the battery run-time.

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). Anybody
connecting additional equipment 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 representative or the Medela
Customer Service Department.
