Intended use

Control Panels and Panel PCs with a compact push-button extension enable the user-specific arrangement
of electromechanical push-button keys with signal lamp directly on the operating unit. It enables precise
adaptation of the Control Panel to the machine control requirements. In many cases a machine operator
control panel is no longer required, since all functions are integrated in the Control Panel.
Improper use
Do not use the compact push-button extensions in the following areas:
• potentially explosive atmospheres
• Areas with extreme environmental conditions, such as particularly high or low temperatures above and
below the operating temperature range
• Areas in which the device is loaded beyond the EMC interference immunity
• Areas (e.g. residential areas) in which the EMC requirements for interference emissions are
inadequate
• Areas in which the device is loaded beyond its shock resistance
