relief and screw the strain relief tightly into
place, see page 24.

Connecting the gas cylinders

WARNING
Risk due to gas supply failure
Using a pressure reducer without the
required pressure sensor in place of a Dräger
pressure reducer or connecting a central
supply hose to the connection for the
external gas cylinders will prevent the
availability of the gas cylinders from being
monitored during the system test and while
the system is in use. The back-up
functionality may be compromised.
If the gas cylinder monitoring function is not
available, the user must employ suitable
pressure monitoring conforming to
ISO 80601-2-13 which allows the pressure
indicator to be read from the user's operating
location at the front. Do not connect central
supply hoses to the connectors for external
gas cylinders.

WARNING
Risk of injury or damage to the device
Defective pressure reducers can cause the
connected device to malfunction.
– Service the pressure reducer regularly.
Follow the information in the chapter
"Maintenance".
– If signs of wear are visible, replace the
pressure reducer.
Connections of gas cylinders and pressure
reducers must be undamaged as well as free of
dust, particles, and grease. Otherwise, there is risk
of fire.
When handling pressure reducers, observe the
relevant national laws and regulations.
Special features of the ceiling-mounted version
