Frequently Asked Questions (FAQ)
Q: Can the module be inserted or removed while system power is on?
A: No. The module must only be handled with the system powered down.
Q: Is periodic calibration required?
A: No. The device contains no user-serviceable parts and does not require calibration.
Q: How is terminal block and I/O card compatibility ensured?
A: The rotary keying system automatically aligns terminal blocks with the corresponding I/O cards after installation.
