Configured for secure hardware housing in D20M system platforms, the GE Fanuc 500-0305 (500-0305 Robust Single-Slot Chassis) provides direct physical support and environmental shielding for a single circuit board or module.

Hardware Specifications

Backplane Bus Communication Velocity Licences

The integration of the 500-0305 chassis within the D20M system necessitates alignment with backplane bus communication standards. As a passive mechanical housing, the chassis facilitates the signal integrity required for high-velocity data transfer between the installed module and the host system backplane. Firmware flash compatibility and bus protocol synchronization remain the responsibility of the active module housed within the chassis. Users must verify that the installation site provides adequate clearance for EMI/RFI shielding effectiveness, as the chassis design relies on conductive continuity to maintain ground reference across the system rack.

Frequently Asked Questions

Q: Does the 500-0305 chassis support hot-swapping of the contained module?

A: No. Power to the D20M system backplane must be isolated before the insertion or removal of any module from the chassis to prevent electrical arcing or backplane bus contention.

Q: How should the chassis be grounded to ensure effective EMI/RFI protection?

A: The chassis must be secured to a conductive, grounded mounting surface using the designated grounding points. Ensure the connection to the cabinet protective earth (PE) bus is verified with low-resistance measurements to maintain electromagnetic compatibility.

Field Installation Guidelines

• Mounting: Utilize the provided mounting points to secure the chassis to a standard industrial panel or rack. Ensure the 782 mm x 356 mm x 835 mm dimensions are accounted for in the cabinet layout.
• Shielding: Ensure the chassis enclosure remains fully intact to maintain EMI/RFI attenuation. Any modification to the chassis housing may compromise protection against external radio frequency interference.
• Module Seating: Insert the circuit board into the slot until the connectors are firmly seated against the backplane. Verify that the module locking mechanism is engaged to prevent displacement due to mechanical vibration.
• Environmental: Ensure the installation location is free from excessive conductive dust or moisture, which could degrade the performance of the shielded housing.
