ESO 2 ICU Ventilator 8 User Manual
Description
3.2.2 Electrical System
The ventilator has a single connection (1) to a mains power
supply, and an integral battery backup.
WARNING
1. Always use a mains power outlet socket that can be
easily accessed.
2. To isolate the ventilator from the mains power supply:
Disconnect the mains cable from the hospital power
outlet.
Mains Supply
The mains supply inlet is designed for connection to the
following mains voltage supplies:
200 to 240 VAC, 50 to 60 Hz, 0.6 A max
110 to 120 VAC, 50 to 60 Hz, 1.2 A max
Note that the ventilator adjusts automatically to the supply
voltage range.
The connector is a standard IEC type.
Back-up Battery
In the event of mains electrical failure, the back-up battery
cuts in automatically. The back-up battery will power the
ventilator for the period listed below if the battery has been
maintained in a fully charged condition.
NOTE
Manual Delivery of Fresh Gas is not possible.
Battery back-up period
A fully charged battery will power the ventilator for
approximately 60 minutes (depending on ventilator settings).
Charging the battery
Battery charging takes place automatically when the ventilator
mains lead is connected to a ‘live’ mains supply.
The power on/off indicator on the ventilator front control panel
will show an amber light during charging (see section 3.2.3).
NOTE
1. The stated battery back-up period will only be available if
the battery is kept fully charged.
2. If the battery has been allowed to discharge below the
LOW BATTERY condition, the ventilator will not function
correctly until the voltage raises above the LOW BATTERY
level.
3. A fourteen hours recharge will be necessary to bring the
battery to full charge.
Battery care
See Appendix 1 for battery care procedures.
