Overview
Enclosures with standard and customized equipment
Enclosed pushbuttons and indicator lights are used as hand op-
erated control devices for separately allocated control units and
cabinets.
Enclosures with handle are available for suspension
(e.g. for crane control units).
The enclosed pushbuttons and indicator lights are available with
conventional controls as well as for connection to the AS-Inter-
face bus system.
The following versions are available:
• Enclosures with standard fittings
with 1 to 3 command points
• Enclosures with customized equipment
with 1 to 6 command points
• Empty enclosures (individual parts must be ordered sepa-
rately)
Customer-specific enclosures
On request enclosures with more than 6 command points can
also be supplied with AS-Interface connection.
Use the configurator for selection.
For AS-Interface enclosures see page 13/96.
