C. Chassis Grounding
The HSD-400 terminal tray-mounted assemblies must be electrically bonded to the
airframe. Ensure the mating surfaces are free from contaminants such as paints or other
non-conductive elements. Where surface preparations are insufficient to ensure a proper
bond, the use of a short, tin-coated, copper bonding strap of at least ¼ inch wide is
recommended. The LRU and tray assemblies should provide a low impedance path of
<0.2 ohms.
