Safety notes
2.1
Preliminary information
The following general safety notes serve the purpose of preventing injury to persons
and damage to property. They primarily apply to the use of products described in this
documentation. If you use additional components, also observe the relevant warning
and safety notes.
2.2
Target group
Software specialist
Any work with the software may only be performed by a specialist with suitable train-
ing. A specialist in this context is someone who has the following qualifications:
•
Appropriate training
•
Knowledge of this documentation and other applicable documentation
•
SEW‑EURODRIVE recommends additional training for products that are operated
using this software.
2.3
Designated use
The interface adapter USM21A is designed for connecting an engineering PC with a
USB interface to the diagnostic slot of a unit from SEW‑EURODRIVE.
2.4
Network security and access protection
A bus system makes it possible to adapt electronic drive technology components to
the particulars of the machinery within wide limits. There is a risk that a change of pa-
rameters that cannot be detected externally may result in unexpected but not uncon-
trolled system behavior and may have a negative impact on operational safety, system
availability, or data security.
Ensure that unauthorized access is prevented, especially with respect to Ethernet-
based networked systems and engineering interfaces.
Use IT‑specific safety standards to increase access protection to the ports. For a port
overview, refer to the respective technical data of the device in use.
