Design and Function
2.6.1 Electrical connection
Observe the country-specific regulations when making connections (e. g. in Germany DIN VDE
0100 with residual current device).
This appliance is intended for operation on an electrical power system with a system imped-
ance Z
max
at the point of transfer (service line) of a maximum of 0.292 ohm. The operator must
ensure that the incubator is operated only on an electrical power system that meets these
requirements. If necessary, you can ask your local energy supply company what the system
impedance is.
2.6.2 Connection of external appliances
Only appliances may be connected externally (depending on the model, USB, RS 232, RS 485,
Ethernet, printer) whose interfaces comply with the requirements for safety extra-low voltage
(e.g. PC).
2.6.3 Gas connection
The oven can be connected with the supplied compressed air hose via a pressure regulator
with gas bottle monitor (DIN 8546) to a CO
2
compressed gas bottle or directly to a central CO
2
gas supply.
For models with the CO
2
or premium modules, two gas bottles with quick release connectors
can be connected. If equipped with the O
2
module, an N
2
gas bottle can be connected instead
of a second CO
2
gas bottle ( Fig. 4 ).
The pre-pressure must not exceed 1.2 bar. A value between 0.8 and 1 bar is considered to be
an ideal value.
2.6.4 Water connection
For models with a humidity module, the incubator can be connected with the supplied hose
to the also supplied water supply tank.
2.7 Intended use
INCO incubators may only be used for incubating cell cultures or similar. Any other use is
improper, and may result in hazards and damage.
The incubators are not explosion-proof (they do not comply with workplace health & safety
regulation VBG 24). The chambers may only be loaded with materials and substances which
cannot produce any toxic or explosive vapours at temperature ranges up to 50 ºC, and which
themselves cannot explode, burst or ignite.
The incubators may not be used for drying, vaporising and branding paints or similar materi-
als, the solvents of which could form an explosive mixture when combined with air. If there is
any doubt as to the composition of materials, they must not be loaded into the incubator. Po-
tentially explosive gas-air mixtures must not be produced, either in the interior of the chamber
or in the direct vicinity of the appliance.
The incubator may not be used for sterilisation purposes. It is not a steriliser with respect to
the Law on Medical Devices.
Only gas bottles with a pressure regulator may be connected to the gas connections of the
oven. Introducing other gases or materials than CO
2
or N
2
is not permitted.
