EvitaXL

Mains power/DC power operation
Components and definitions
Mains power/DC power operation*
EvitaXL contains a DC power supply with integrated battery to
ensure that operation of the ventilator can continue for at least
10 minutes following a power failure (provided that the battery
is fully charged).
The ventilator can be powered from an external battery via this
DC power supply.
Components and definitions
DC power supply FB and DC power supply MB
The DC power supply in EvitaXL is available in two versions,
both of which operate in a similar manner:
— DC power supply FB (Fixed Batteries): in this version, the
batteries are located inside the power supply and are only
accessible after removing the power supply.
— DC power supply MB (Movable Batteries): the batteries for
this version are located in a drawer. A filter is installed in
front of the power supply fan.
Whenever reference is made in these Instructions for Use to
the "DC power supply", the information applies equally to both
versions. If the information applies to only one version, the version
concerned is specified by reference to either the "DC
power supply FB" or "DC power supply MB".
Integrated battery
The two 12 V lead-gel batteries integrated into the DC power
supply are always supplied with the DC power supply.
The integrated battery in the DC power supply is only fully
charged after charging for 24 hours.
● The integrated battery in EvitaXL must be charged for at
least 24 hours, see "Charging the batteries", page 171.
The integrated battery is intended exclusively for emergency
use and not for normal operation!
It is therefore essential to operate the ventilator with external
battery power or mains power again as soon as possible
after switching over to operation with integrated battery.
* An Evita 4 oder Evita 2 dura unit which has been upgraded with the
EvitaXL option can also be operated without the DC option.
External batteries (optional)
Additional rechargeable 12 V or 24 V lead-gel batteries which
are connected to EvitaXL via the DC socket. The external batteries
are not supplied with the DC power supply.
It is advisable to use 24 V lead-gel batteries (or two 12 V leadgel
batteries connected in series) with a minimum capacity of
15 Ah. The efficiency of the DC power supply and the associated
duty period is significantly higher when using these batteries
than when using 12 V batteries with comparable
capacity.
The external battery may also take the form of two 12 V leadgel
batteries accommodated in the base of the trolley. Refer to
the Order List for details for purchasing these batteries and
the required connecting lead.
Commercially available rechargeable lead-gel batteries can
also be used. For requirements to be met by the external batteries,
see "Technical data", page 200.
Only use rechargeable batteries!
Disposable batteries may explode during operation with
mains power on account of the charging function of the DC
power supply!
DC socket
Socket on the back of the DC power supply for connecting an
external battery.
This socket is identified as follows:
DC power supply FB: 12 V; 24 V; VDC
DC power supply MB: 12 V/24 V; F200; F30A 80V.
Only use rechargeable batteries!
Disposable batteries may explode during operation with
mains power on account of the charging function of the DC
power supply!
Only external batteries (see page 170) may be connected
to the DC socket and only using the connecting leads
specified in the Order List.
Mains-powered equipment must not be connected to the
DC socket!
Mains power supply (mains power)
AC power supply (= mains power supply) for the ventilator via
the mains connecting cable.
For voltage ranges/characteristics of the mains power, see
"Operating data", page 196.
