After switching the HMI device off, wait for at least 1 minute before opening it.
Before opening the housing lid users must ensure that all non-intrinsically safe circuits have
been switched off. Circuits supplied from different sources may be connected !
Please note that all associated equipment (such as the SK-KJ1710, for example) must also

10.4 Industrial Security
Our products with Industrial Security functions support the secure operation of plants, systems
and equipment. Protection against cyber threats requires an all-encompassing Industrial Security
concept. The key to a successful concept is integrated implementation, continuous maintenance
and state-of-the-art technology. This is the responsibility of the plant operator.
The following are key issues for an effective Industrial Security concept:
Prevention of unauthorised access to plants, systems, equipment and networks
Systems, equipment and components should only be connected to the company intranet or
the internet if and when required
Employ protective measures such as firewalls and network segmentation
Only use the latest software product versions
