The following must be distinguished in the case of connection via screw terminals:
terminal plugs for voltage connections and
terminal plugs for current connections.
The terminal screws have a slot head for tightening or loosening with a flat screw driv-

The voltage connection terminal modules are available in 2 variants (Figure 2-9).

There is one version of a terminal block for current connections to a 7SA6. The termi-
nal block is illustrated in Figure 2-11.
The correlation between the terminals and their terminal numbers is the same for the
current terminals as shown in Figure 2-10.
