CRITICAL WARNING: RISK OF ELECTRIC SHOCK
Disconnect all power sources before installation, servicing, or removal. Failure to de-energize the equipment can result in severe injury or death. All work must be performed by qualified personnel in accordance with local electrical codes and safety regulations.
Ensure the panel cutout dimensions precisely match the device specifications for a secure and environmentally sealed fit. Clean the mounting surface of any debris or contaminants.
Insert the thin client into the panel cutout from the front. Secure it from the rear using the provided mounting clamps. Tighten the clamp screws evenly in a diagonal pattern to ensure uniform gasket compression.
Connect the designated PE terminal on the device chassis to the cabinet's main protective earth bus using a low-impedance conductor. This is critical for operator safety and noise immunity.
Connect a stable, correctly rated 24V DC power source to the power supply terminals. Ensure correct polarity (+/-). Use appropriately sized wiring and verify the power supply is properly fused.
Connect the Ethernet cable to the network port. If required, connect any USB peripherals. Ensure all cables are routed to prevent strain and are separated from high-voltage power lines to minimize interference.
