PRODUCT- AND TECHNOLOGY-RELATED SAFETY
INSTRUCTIONS
Hazardous movements!
Risk of injury due to incorrect connection or incorrect activation of electrical and
electronic devices and resulting unforeseeable machine movements.
▶ Observe safety according to EN ISO 13849 or IEC 62061.
▶ If persons have to enter the hazard zone while the control is active, provide
superordinate monitoring functions or measures for personal safety. These
measures must be provided according to the specific data of the system and
on the basis of the risk and error analysis of the system manufacturer/user.
In this connection, the safety provisions applied for the system must be taken
into account.
▶ Failures and defects in the control current or the energy supply can result in
uncontrolled machine movements.
▶ Electronics emit interference to other electronics within the permitted limit
values and also react to interference. This can cause malfunction in the
control process. Only use electronics below EMC limit values or provide
appropriate shielding.
▶ Electrostatic processes, an inadequate grounding concept or missing
equipotential bonding can lead to damage to the electronics and hence
cause malfunction or uncontrolled movements of the machine. Ensure proper
grounding and provide equipotential bonding.
▶ Using the product outside the specified IP protection class can result in
short-circuit and malfunction and hence in uncontrolled machine movements.
Therefore, use the product only within the IP protection class and in
environments as specified in the data sheet.
▶ Provide safety functions for personal safety separately. Amplifiers, command
value processing cards and control electronics themselves do not include
safety functions for personal safety and are no safety-related components.
▶ Avoid contact with salt-laden environments and adhere to the ambient
temperature given in the data sheet.
▶ In the event of an emergency, fault or other abnormalities, switch the system
off and secure it against being switched on again.
High electrical voltage due to incorrect connection!
Danger to life, risk of injury due to electric shock.
▶ When carrying out any work, disconnect the relevant machine section from the
power supply and protect it against being switched on again.
▶ Only connect devices, electrical components and cables which feature
protective extra low voltage (PELV) to connections or terminals having
voltages from 0 to 50 Volt.
▶ Only connect voltages and power circuits that feature safe isolation
from dangerous voltages. Safe isolation can be achieved with isolation
transformers, safe optocouplers or mains-free battery operation.
▶ Always connect all cables to the provided connections. Avoid open cables or
contacts.
