4. Preparation for Use

4.1. Setup

4.1.1. Connecting the electrical power supply
The e500 is designed to operate using one of the following power
options:
• Internal rechargeable battery pack
• AC/DC external power supply.
• A fully charged battery must always be installed for safety
reasons, even when operating from an external power supply,
so that continuous ventilation is not interrupted in the absence
of external power.
• The use of batteries, other than those specified, may cause the
ventilator to fail and/or endanger the patient and operator.
• Connect the ventilator to an external electrical source right
away if the "Battery Empty" alarm is triggered.

4.1.2. Installing / replacing the battery

1. Ensure the ventilator is turned off and unplugged from the
mains electrical supply.
2. Turn the two screw knobs on the battery compartment cover
anticlockwise and open the cover downwards.
3. Disconnect the battery leads and pull out the battery pack
using its stand-off.
Always use the battery stand off to pull out the battery pack,
never pull the battery by its leads (Figure 05).
4. Insert the fully charged battery such that the battery stand-
off is positioned upwards (as per illustration below), attach
battery connectors. Close cover and turn screw knob clockwise
to secure.
