Installation Guidelines

CRITICAL WARNING

Failure to ensure adequate ventilation clearance around the unit can lead to overheating, component failure, and system shutdown. Maintain specified clearances on all sides as per the enclosure design. Disconnect all power sources before installation or maintenance.

1 Verify the panel cutout dimensions against the device's mechanical drawings. Ensure the mounting surface is clean, flat, and can support the weight of the unit.
2 De-energize the main control cabinet and apply Lockout/Tagout (LOTO) procedures. Confirm the absence of voltage before proceeding.
3 Insert the Panel PC into the prepared cutout from the front of the panel. Ensure the front bezel gasket is properly seated against the panel surface to maintain ingress protection.
4 From the rear of the panel, install and progressively tighten the mounting clamps in a crisscross pattern to ensure even pressure distribution. Do not overtighten.
5 Connect the protective earth (PE) conductor to the designated chassis grounding point using a low-impedance connection. This is critical for electrical safety and noise immunity.
6 Connect the AC power supply, Ethernet, PROFIBUS, and any other required I/O cables. Ensure all connectors are securely seated. Route cables to prevent strain and interference.
