For AC-power-equipped appliances you should provide an external Surge Protection Device.

The nominal working voltage range for a DC-power-equipped appliance is -48 VDC. This appliance can operate over an input voltage range from -38 VDC to -72 VDC.

For DC-power-equipped appliances, you must provide an external certified, dedicated circuit breaker rated at a minimum of 20 A for each DC power supply.

For DC-power-equipped appliances, you must supply four DC power cables that meet your local code requirements.

You must provide a good earth ground for the rack.

On DC-power-equipped models, you must supply a ground cable for the power supply. We recommend using a ground cable identified according to local standards to ground the appliance.

You must use only copper grounding conductors.

For a ground wire attaching directly to the rack, we recommend using the following ground lug: Panduit P/N LCDX8-10A-L, #8 AWG, #10 stud, 0.625-inch spacing.

To ensure a reliable low-resistance ground bond, you must provide and use star washers and thread-forming screws with paint-piercing washers to secure the ground wire to the rack frame, and to secure the appliance chassis to the rack.

If you connect the ground wire to a ground rail in the rack or to any other grounding facility provided by the site, you must use the appropriate fasteners to ensure a reliable ground bond. When the ground wire is attached with bolts or to studs, locking washers can help ensure the ground wire does not come loose.
