Installation Guidelines

1. 1 De-energize the control cabinet and disconnect the main power supply before beginning installation.
2. 2 Verify a zero-energy state using a properly rated multimeter. Apply personal and equipment locks and tags per LOTO protocol.
3. 3 Mount the Microbox PC securely onto a DIN rail or panel surface within the enclosure, ensuring adequate clearance for ventilation and cable access.
4. 4 Connect a low-impedance protective earth (PE) ground wire to the designated chassis terminal. This is critical for safety and noise immunity.
5. 5 Connect all required communication cables, such as PROFIBUS DP and Ethernet, ensuring proper shielding and termination.
6. 6 Connect the DC power supply wiring to the correct terminals, verifying voltage and polarity before connection.
7. 7 After clearing all tools and personnel from the enclosure, remove LOTO devices and re-energize the cabinet. Verify the PC boots correctly and establishes communication.
