the earthing diagram, cleanly and permanently,
to an electrically clean earthing point, - e.g.
with an earthing bar on your system.

In the event of an electrical accident, it must be
possible to quickly disconnect the pump, and any
electrical ancillaries which may possibly be
present, from the mains.
