closing an open window.
1.4 Application and Use
It would be beyond the scope of these safety instructions
to list all the valid regulations and guidelines.
Always make sure that your system
corresponds to the valid regulations. Pay
particular attention to: the aperture cross-
section of the window, the opening time and
opening speed, the temperature resistance of
the cables and equipment, cross-sections of
the cables in relation to the cable lengths and
power consumption.
