block group 14 a (see the figure above) in the control
panel. If the STAZ-81 energy analyser has been selected,
connect the incoming supply directly to the energy ana-
lyser (see page 10). Connect the protective earth directly
to the earthing bar, 7, (see the figure above).
Each incoming supply must be provided with a manu-
ally operated lockable main circuit breaker/load inter-
rupter confirming to Machinery Directive 2006/42/EC
