Install circuit breaker covers and pan-head screws.
Install the rating plug into the trip unit (Figure 3-5 and
Table 3.1). The pins on the circuit board must line up
with the sockets in the rating plug and require only
minimal pressure to install. Do NOT attempt to
force the rating plug into the trip unit.
