Installation Guidelines

• Install the terminal onto a 35 mm DIN rail (EN 60715) and secure it using the integrated locking mechanism.
• Use the double slot and key connection for reliable side-by-side assembly with other EtherCAT terminals.
• Connect sensors using solid or flexible conductors; utilize spring-actuated terminals for secure contact (stripping length 8–9 mm).
• Ensure wiring practices adhere to EMC standards EN 61000-6-2/EN 61000-6-4 to maintain signal accuracy.
• Operate within the ambient temperature range of -25 to +60 degC to ensure the specified measuring performance.
