BCU Warning Labels
A supply of warning labels (form number X39001257-01) is shipped with
each BCU (see Figure 9). Use these labels to warn operating, mainte-
nance, and service personnel about the potential hazards associated with
automatically controlled equipment.
Before making any control wiring connections, place one or more labels in
conspicuous locations on each piece of controlled equipment.

Installing and Removing the BCU Cover
The BCU has a resin cover that protects the internal components from
damage. The cover slips easily onto the BCU metal back panel and locks
for security purposes.
