Installation Guidelines
CRITICAL WARNING: This equipment contains components sensitive to electrostatic discharge (ESD). Use a properly grounded wrist strap and work on an anti-static mat during installation and handling to prevent permanent damage.
-
1
Ensure the control cabinet or mounting location is de-energized and locked out according to site safety procedures before beginning installation.
-
2
Securely mount the Box PC chassis within the enclosure using all provided mounting points. Verify there is adequate clearance for airflow and cable routing around the unit.
-
3
Connect a low-impedance protective earth (PE) conductor to the designated grounding terminal on the PC chassis. This is critical for both safety and noise immunity.
-
4
Connect the AC power cable to the power supply unit. Ensure the source voltage matches the 110/230V AC rating.
-
5
Connect all required peripheral and communication cables, such as Ethernet, USB, and video. Route cables neatly and secure them to prevent strain on the connectors.
-
6
After closing the enclosure, restore power and verify that the PC boots correctly and all system fans are operational.
