Thermal Problems
In order that the LCD-monitor maintains an optimum operating temperature while in use, air must be
allowed to circulate freely around the SCD 1297 enclosure. It is particularly important that the rear of
the system is kept free.
Please bear in mind that increased temperatures can lead to defects and to a significant reduction in
the lifetime of the monitor.
EMC Problems
This LCD-monitor is a piece of equipment designed for building into an industrial system. The
operator of the entire plant is responsible for maintaining electromagnetic compatibility according to
EMC laws.
Safety Problems
All voltage and signal connections must adhere to appropriate legal requirements.
Ergonomics
The screen should be easily viewable from all sides and without reflections.
2.2.1 Installation of the AC/DC-power supply unit or 24V-DC/DC-
Converter
Either an AC/DC power supply unit or a DC/DC converter can be used to supply the control panel with
24DC. If an AC/DC power supply unit is used, it is attached to the enclosure using the bracket
indicated in Fig. 1 on page 10.
If the DC/DC converter, which is delivered with the unit, is to be used then it should be inserted below
the AC/DC power supply unit shown in Fig. 1, so that the 24V connector is accessible. The DC/DC
converter should then be screwed to the enclosure using to the two holes provided for the bracket.
