4.2 Connecting to External AC Power
Any of four power sources: AC power, 12 – 30 VDC power, Internal Battery power, or Auxiliary DC car
adapter (cigarette lighter) can be used to power the ventilator. But when AC power is available, the
ventilator will automatically select AC power as its operating power source.
To prevent accidental disconnection of the AC power cable, use the power cable holder ( Figure 4-1 ,
item 1) that is inserted into the notch ( Figure 4-1 , item 2) of the battery cover (follow the instructions
on the next page).

Caution
•
The use of any accessory other than those specified by Puritan Bennett, may lead to an increase in
electromagnetic emissions or a decrease in the equipment’s insulation against electromagnetic emissions.
•
The Puritan Bennett 540™ Ventilator requires special precautions for electromagnetic compatibility and
should be installed and started according to the recommendations stated in
Appendix A, “Specifications” . In
particular, the use of nearby mobile and portable communications equipment using radio frequencies (such
as mobile telephones) or other systems exceeding the levels set in the IEC 60601-1-2 standard may affect the
ventilator’s operation.
WARNING
•
The power supply to which the ventilator is connected (both AC and DC) must comply with all current
and applicable standards and provide electrical power corresponding to the voltage characteristics
inscribed on the rear of the ventilator to ensure correct operation.
•
Never connect your ventilator to an electrical outlet controlled by a wall switch because the power may
be inadvertently turned off.
•
To be held correctly, the AC power cable must be fitted into the cable holder incorporated in the battery
access cover and located under the AC power socket. Refer to the following instructions.
Caution
•
Connect the external electrical power source by first connecting the power cable to the ventilator and then to
the external power source. Follow the reverse procedure to disconnect the device from electrical power
sources.
•
Ensure that the AC power cable is in perfect condition and not compressed.
•
Do not leave power cables lying on the ground where they risk being stepped on and damaged.
