4.9 Supply interface
All supply connections are installed in the supply
interface (control box [1]) in the rear of the device.
Gas connection:
The gas supply lines between the device and the gas
supply system are connected using the supplied
connecting hoses. O

is supplied to the device
through connecting sleeve [2]. CO
2
is connected to
sleeve [3].
All process gases must be supplied to the device at a
fixed pressure that has been preset within a range of
0.8 to 1.0 bar and must remain unchanged.
Before the gases are fed into the work space, they flow
through a gas inlet filter with a separation rate of 99.97
% for a particle size of 0.3
μ m (HEPA filter quality).
The illustration shows the optional combined gas
connection without the optional gas monitoring
system.
Label:
The label [4] contains information about gas supply,
an alarm contact terminal legend, and notes about the
electrical fusing of the device.
RS 232 interface:
Via the RS 232 interface [5], the incubator can be
connected to the serial interface of a PC. This
connection allows the computer-aided acquisition and
documentation of the major operating parameters
(temperature, CO

concentration, error codes,
etc.).
USB interface (optional):
As an alternative to the RS 232 interface [5], the
incubator can be connected to a PC via the optional
USB interface [6]. This connection - USB 1.1 /
USB 2.0 full speed compatible - allows the computer-
aided acquisition and documentation of the major
operating parameters (temperature, CO
