The AC input voltage ground wire must be connected to the PE terminal located on the front
panel of the CDHD2S. This is good for safety and reduces electromagnetic interference.
The system uses a single point ground (start wiring) to avoid ground loops.
It is strongly recommended to mount the CDHD2S on a metal backplane and provide a high
frequency ground to ground the backplane. Electrical connections are provided throughout the
entire back of the drive panel. It is recommended to use current-conducting plate such as aluminum
or galvanized steel sheet. For painted and other coated metal panels, remove any coating behind
the drive. The goal is to provide a low impedance path between the filter, drive, power supply, and
ground for high frequency signals that may cause electromagnetic interference. Use flat braided
wire or copper busbar for high frequency grounding. When connecting to high frequency ground,
use the shortest braided wire possible.
Ensure good connections between cabinet components. Connect the back panel and cabinet
door to the cabinet body with multiple conductive braided wires. The grounding connection must
not be made by hinges or mounting bolts. Ensure that the cabinet is well grounded with the right
grounding system. The grounding lead shall be the same as or
smaller than the main power lead.
The host computer must also be properly grounded.
