Intended Use
The system housing is for indoor use only, and
may only be used with parts indicated in this
document. Not explicitly mentioned parts may
not be installed or connected. This also applies
to cables. Usage is only allowed in explicitly
indicated configurations and combinations of
parts and with the specified software and
firmware.
Do not install and use this system housing
before you have read all relevant documents.
You must read the safety instructions and all
other directions for use before you start any
work or activity with this system housing.
The system housing has no certified func-
tional safety on board. This means that all pre-
cautions for a safe operation must be ensured
by external components.

Maximum altitude
Free air flow in vertical direction is required
above and below the system housing for a dis-
tance of minimal 10 cm for forced cooled sys-
tems and 20 cm for convection cooled systems.
If convection cooling is used (instead of
forced cooling) the system housing must be in-
stalled vertical to ensure sufficient free air flow
through the ventilation holes. In particular,
bend cables away from the ventilation holes as
near to the connectors as possible.
