3.3 Compartment area
The front enclosure of each section is divided into
individual compartments. These compartments
house either a low voltage power circuit breaker
or are used to mount instruments, control
components and other ancillary devices.
3.4 Instrument panel (AKD-20 only)
A standard instrument panel, Fig. 3.3, is located
above each breaker compartment eliminating
cross-hinge wiring. When required, optional
devices may be included and mounted on the
front face of the panel such as breaker control
circuit fuses, pilot lights, and a RELT switch.
Fuses for the charge, close, and trip circuits of the
electrically operated EntelliGuard G breakers are
mounted on the panel. Routine wiring inspections
and fuse checks or fuse replacements can be
performed with the breaker compartment door in
the closed position so that operators are protected
from the energized primary circuits.

Circuit breaker control fuse panel (Entellisys only)
Control fuses for the charge, close and trip circuits
of electrically operated EntelliGuard E circuit
breakers are mounted in the middle right side
of the cassette, behind the compartment door.
Control fuses for the SET and RESET coils of the
optional Network Interlock breaker accessory are
also mounted on the same panel. See Fig. 3.4.
3.5 EntelliGuard messenger (Entellisys only)
An EntelliGuard messenger, Fig. 3.5, is located
above each breaker compartment. The messenger
provides an interface between the circuit breaker,
the breaker compartment, and the Entellisys
system. For additional information and
instructions, reference DEH-501.
