Installation Guidelines
-
ESD Protection: Always utilize an anti-static wrist strap and proper grounding techniques when handling the card to prevent damage to sensitive electronic components.
-
Power Status: Ensure the host industrial PC is completely powered down and disconnected from the AC supply before inserting or removing the PCI card.
-
Seating: Ensure the card is firmly seated in a compatible PCI slot; secure the mounting bracket to the chassis to prevent mechanical stress.
-
Cable Routing: Keep DeviceNet network cabling separated from high-voltage power lines and sources of significant electromagnetic interference (EMI) to ensure optimal signal quality.
