Installation Guidelines

1. 1 De-energize Equipment: Verify that the control panel is completely de-energized and locked-out/tagged-out (LOTO) before beginning installation.
2. 2 Panel Mounting: Secure the Panel PC into the designated panel cutout using all provided mounting clamps. Ensure an even torque on all clamps to maintain the IP rating and prevent chassis warping. Verify adequate clearance for ventilation around the rear of the unit.
3. 3 Protective Earth (PE) Connection: Connect the chassis grounding terminal to the main panel protective earth bus using a low-impedance conductor. This is critical for operator safety and noise immunity.
4. 4 Power Supply Wiring: Connect the 24 VDC power supply to the designated terminals. Use appropriately sized conductors and ensure correct polarity. It is recommended to use a dedicated, stabilized power supply.
5. 5 Communication Cabling: Route all communication cables (Ethernet, PROFIBUS, USB, RS-232) separately from high-voltage power lines to prevent electromagnetic interference. Use shielded cables where specified and ensure shields are properly terminated.
