Safety instructions

The following safety instructions must be followed during installation and working with networks and the software.

Mounting

• Never work on live equipment. Always switch off the power supply for the device before installation, troubleshooting or maintenance. Protect the device against unintentional switching on.
• Observe the relevant accident prevention regulations for your machine (e.g. the BGV A 3, electrical systems and equipment).
• Ensure standard-compliant connection and avoid risks to personnel. Ensure that data and supply cables are laid in a standard-compliant manner and ensure correct connection.
• Observe the relevant EMC guidelines for your application.
• Avoid polarity reversal of the data and supply cables, as this may cause damage to the equipment.
• The devices contain electronic components, which may be destroyed by electrostatic discharge when touched. Observe the safety precautions against electrostatic discharge according to DIN EN 61340-5-1/-3.

Working with networks

• Restrict access to all devices to an authorized circle of persons.
• Change the default passwords to reduce the risk of unauthorized access.
• Protect the devices with a firewall.
• Apply the IT security precautions according to IEC 62443, in order to limit access to and control of devices and networks.

Working with the software

• The sensitivity of a PC against malicious software increases with the number of installed and active software.
• Uninstall or disable unnecessary software.
