Installation Guidelines
CRITICAL WARNING: RISK OF EQUIPMENT DAMAGE AND ELECTRIC SHOCK
Installation must be performed by qualified personnel only. Always de-energize the control cabinet and follow Lockout/Tagout (LOTO) procedures before handling, installing, or removing this device. This unit contains components sensitive to electrostatic discharge (ESD). Use appropriate ESD protection, such as a grounded wrist strap, at all times.
-
1
Verify the received part number 6ES7647-7BJ40-4EM0 matches the project requirements. Inspect for any signs of shipping damage.
-
2
Ensure the control cabinet is fully de-energized and locked out. Verify zero voltage with a calibrated multimeter before proceeding.
-
3
Securely mount the Microbox PC to a DIN rail or panel surface inside the enclosure, ensuring adequate clearance for ventilation and cable access.
-
4
Connect the specified DC power supply to the correct terminals. Ensure the power source is stable and within the device's rated voltage range.
-
5
Connect the chassis to the main protective earth (PE) ground point of the cabinet using a low-impedance conductor.
-
6
Connect all required peripherals, such as network cables (Ethernet), display ports, and USB devices.
-
7
After all connections are secure, remove the LOTO device and re-energize the cabinet. Verify the PC boots correctly and establishes communication.
