5.3.4 Control Section
The Control Section is located in front of the I/O Section and contains the NXG II Controller,
low voltage apparatus, and the auxiliary voltage disconnect switch; the Control Door is
considered part of this section in reference to the "A" and "B" drawings. The door in the
control section is hinged so that it can swing open 150 degrees to allow access to the
input/output section for purposes such as terminating medium voltage cables. Upon opening
the control door, two Cell Section Components polyglass barriers are encountered as
describe previously. In addition, the terminal blocks are accessible with the door in the open
position. See Table "Control Section Components" for the components found in this section.
