Other requirements
To completely separate the chamber from the power supply, you must disconnect the power plug. Install
the chamber in a way that the power plug is easily accessible and can be easily pulled in case of danger.
With an increased amount of dust in the ambient air, clean the condenser fan several times a year. We
recommend checking the fan grid (behind the left maintenance access flap) every week. In case of visible
dirt accumulation, disconnect the chamber and clean the fan grid by suction.
Avoid any conductive dust in the ambiance according to the chamber layout complying with pollution degree
2 (IEC 61010-1).
9. Installation and connections
9.1 Connecting the CO
2
pressurized gas cylinder
Connecting the CO
2
pressurized gas cylinder serves to ensure the effectiveness of all safety devices. It is
carried out as part of commissioning after the installation has been completed, see chap. 11.1.
9.2 Inertization connections for customer systems
Permanent inertization of the test space displaces atmospheric oxygen and reduces the risk of ignition of
combustible gases or vapors released by escaping or venting the cell(s) into the chamber.
BINDER provides connections for this purpose.

The operator is responsible for provision and control of inert gas (e.g., N

).
The connection is established via a quick-release coupling.
