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 pin assignment.
• 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.
