For fixed-mounted circuit breakers, secondary terminal blocks
mount onto an insulated support frame (Figure 2).

Electrical accessory leads are tagged with numbers associ-
ated with the applicable connection diagram. Leads are also
supplied with keyed secondary connector plugs to ensure
proper connections (Figure 3).
Figure 3. Leads and Connectors (Drawout Configuration Shown)
Secondary connections are made by plugging the connector
plugs into the appropriate location. A connector plug already con-
nected can be removed by squeezing two release tabs together
with small needle nose pliers and pulling out (Figure 4).
