2.1 Mounting SK 2xxE
The devices are available in various sizes depending on their output. They can be mounted on the
terminal box of a motor or in its immediate vicinity.
Motor-mounted version Wall-mounted version
When a complete drive unit (gear unit + motor + SK 2xxE) is delivered, the device is always fully
installed and tested.
IP6x-compliant devices must be installed by NORD since special measures have to be taken. IP6x components
that are retrofitted on site cannot guarantee this degree of protection.
