Installation Guidelines

1. 1 Prepare Mounting Location: Verify that the panel cutout dimensions match the unit's specifications. Ensure adequate clearance for ventilation around the rear of the unit to prevent overheating.
2. 2 Mount the Panel PC: Insert the Panel PC into the prepared cutout from the front of the enclosure. Secure it evenly using all provided mounting clamps and hardware, tightening to the manufacturer's recommended torque specification to ensure a proper seal.
3. 3 Connect Protective Earth (PE): Connect the chassis grounding terminal to the control cabinet's protective earth busbar using a low-impedance conductor. A reliable ground connection is critical for safety and noise immunity.
4. 4 Connect Power Supply: Connect a stable, regulated 24V DC power source to the designated power input terminals. Verify correct polarity (+/-) before energizing the circuit. Use appropriate wire gauges for the current draw.
5. 5 Connect Peripherals: Connect necessary peripherals such as keyboards, mice, and network cables to the appropriate ports. Utilize the front-side USB port for temporary devices like flash drives. Power on the unit and verify system startup and operation.
