Description
The standard cabinet units are supplied with integrated ventilation grilles in the bottom of the
doors as standard.
With option M59, the Cabinet Modules are delivered with closed doors.
Safety information
When closed doors are used, the base plates, which are available as standard for ensuring
a sufficient cooling air supply, are not required.
In this case, the customer must ensure that no dirt/conductive dust or moisture can enter
the Cabinet Module. Cables must not be routed in such a way that they impede the flow of
air through the cabinet floor opening.
If the area beneath the Cabinet Modules can be accessed, the customer must provide
shock protection.
The required ambient conditions must be taken into account to prevent, for example,
overheating of the cabinet and the ingress of dirt or moisture.
When removing doors, take care not to damage the grounding strips attached to them.
Make sure that the strips are reattached properly when the doors are mounted.
Note
The door opening angle with free-standing cabinet units is 180°.
With a side-by-side configuration of the cabinet units, this opening angle is 130°.
For degrees of protection IP23/IP43/IP54 and with option L37 (DC interface incl. pre-
charging input circuit), the door opening angle is only 110° .
