Connect the 0 V connections on all the 24 V power supplies and earth the 0 V mains at a
single point, or ensure that measures are in place to monitor for earth faults.
}
The connection of the 0 V supply to the central earth bar or earth fault monitor must be in
accordance with relevant national regulations (such as EN 60204-1, NFPA 79:17-7,
NEC: Article 250).
}
Connections should be protected from corrosion.

Flexible earthing straps should be used on moving earth parts (e.g. machine parts,
gates). Ensure these earthing straps are as short and wide as possible.
