Technical Specifications

Installation Guidelines

1. 1 Panel Cutout and Mounting: Ensure the panel cutout dimensions precisely match the unit's specifications for a secure, IP-rated fit. Verify the panel material has sufficient structural integrity to support the PC's weight (19.00 kg). Use all provided mounting clamps and tighten them to the specified torque to ensure a uniform seal.
2. 2 Power Connection: Connect a stable, filtered 24V DC power source to the designated terminals. Use appropriately gauged wiring for the load and distance. Ensure the power supply is properly grounded and provides overcurrent protection. Verify correct polarity before energizing the unit.
3. 3 Grounding: A dedicated, low-impedance protective earth (PE) connection is mandatory. Connect the chassis ground terminal directly to the main control panel's ground bus using a short, heavy-gauge wire to minimize electrical noise and ensure safety.
4. 4 Ventilation and Clearance: Maintain adequate clearance around the unit's rear and sides for proper heat dissipation. Do not block ventilation openings. Ensure the ambient operating temperature within the enclosure remains within the device's specified limits to prevent overheating and premature component failure.
