Terminal type, power connections for units of 60 A and higher (continued)
The units are designed for a permanent line supply connection
in accordance with DIN VDE 0160-106, Section 6.5.2.1.
The conductor cross-sections (also for the protective conductor)
must be determined in accordance with the regulations that
apply in each case – e.g. DIN VDE 0276-1000.
