Cabling should be screened and routed away from noise-carrying cables and
machines to reduce interference. The screen can be connected to power earth if
it is not already grounded at the shunt end.
The shunt should be located in the low voltage unswitched return line to
minimise common-mode noise.
These connectors are only used when options are fitted
