Installation Guidelines

• Before removing the module, ensure all fixing screws are completely loosened and the unit is freely movable.
• To remove, push the ejection lever (on the front label) downward and withdraw the module in an upward motion to prevent the triggering of faulty signals.
• To attach, place the module onto the terminal block and press inwards until fully seated; perform this action quickly to maintain system signal integrity.
• Verify correct settings for the bus station number and transmission rate using switch S1.
• Buffer battery maintenance: Replace at least every 6 years, or within 3 months if the "BATI" display appears; use Lithium battery type CR 2477N (HIMA part no. 44 0000018).

Compliance and Certifications

• IEC 61508 (up to SIL 3)
