Ri4Power Form 4a Separation between the busbars and function units and sepa- ration between the individual function units and separation between the connections for conductors fed in from the out- side that are assigned to a function unit, and the connections of all other function units, as well as the busbars. With Form 4a, however, the connections and the function unit are in one compartment. Form 4b Separation between the busbars and function units and sepa- ration between the individual function units and separation between the connections for conductors fed in from the out- side that are assigned to a function unit, and the connections of all other function units, as well as the busbars. With Form 4b, however, the connections and the function unit are like- wise separated. Explanation: Internal separation is met via compliance with protection category IP XXB. For protection against the ingress of solid foreign bodies, protection category IP 2X is a minimum requirement.
