Reverse polarity protection for 3-phase, 3-diode bridge?

[cupoftea]

Hi,
Whats the favoured way for rev pol protection on a 3 phase , 3 diode bridge? Ayk, if a phase goes into neutral connector by mistake, and the neutral to one of the phase connectors, the voltage goes high and the magic smoke comes.

Hi,

A little piece of documentation .. and a worker who can read.
Best if the "documentation" is printed on or close to the connectors.

I don´t feel responsible for the mistakes of others (anymore). It´s just my cost and the benefit for others.
