Step 3: Mount AFM-20DSP

To rack mount the machine, attach both rack ears (by removing the screws from each side of the machine and replacing those screws through the rack ears) or place the machine on a table.

• Ensure that the environment (e.g., maximum ambient temperature & air flow) is compatible for the device.

• Avoid uneven mechanical loading.

• Appropriate consideration of equipment nameplate ratings should be

used for avoiding overloading of the circuits.

• Reliable earthing of rack-mounted equipment should be maintained.
