Does anyone know the rules on devicenet installations in Cl. 1 Div. 2 areas??? We have plug connectors to various devices (which are rated Cl. 1, Div. 2) and I am told I'll need "lock fast" jackets over connectors (to avoid any chance of them falling out) but I can find no written evidence of this. These plugs are made such that they disconnect conductors before they are exposed.
