KSU Grounding
The
Earthling is required for user safety and to minimize EMC interference.
If does not connected mains earth, to ensure proper system operation and for safety purpose, a good earth ground is required. A metallic COLD water pipe usually provides a reliable ground. Carefully check that the pipe does not contain insulated joints that could isolate the ground path. If insulated joints exist, another earth ground source must be used or, if allowed, the joints may be bridged.
A #14 AWG or larger copper wire should be used between the ground source and the connector, CN27, of the KSU. The wire should be kept as short as possible, it is recommended that the wire be no longer than 8 meters.(about 25 feet)
