Grounding the Shelf

Use a 2 AWG wire with a 2-hole copper lug and connect directly to the earth ground point
located on the right side of the back of the shelf. Connect the other end of the wire to a
reliable earth ground. Use the torque setting required by the connector supplier. The 2-hole
lug prevents rotation of the lug and ensures a permanent bonding of ground to the shelf.
The dual hole mount accepts 1/4 #20 screws. Use Panduit LCC2-14AW-Q 2-hole lug or
equivalent.

Shelf Ground Configuration

The AXP1440-C07 shelf was tested in the default configuration of logic ground and shelf
ground connected and does not connect -48VDC return with shelf ground. The system has
been tested in the default configuration and complies with safety and regulatory standards.
As a compliant AdvancedTCA shelf, the AXP1440-C07 allows the system integrator, at
their own discretion, to remove the mechanism which connects logic ground to shelf ground
and install the mechanism that connects -48VDC return to shelf ground.
If the system integrator exercises the option of removing the connections from logic
ground to shelf ground and or adds the connection between -48VDC return and
shelf ground, the responsibility for maintaining compliance to CSA (C/US)/VDE
safety requirements and EMI/RFI emission limits rests entirely with the system
integrator and installer.
