The Power Array Frame
The Symmetra
TM
Power Array frame serves as the base for the
modular components of the system. The MiniFrame pro-
vides bays for three power modules, and two battery mod-
ules. The MasterFrame provides bays for five power mod-
ules, and four battery modules. Both frames provide one bay
at the top right that houses the main intelligence module (MIM)
and redundant intelligence module (RIM).
The bottom of both frames contain wiring input/output ac-
cess panels and terminal blocks. A system enable switch, input
circuit breaker and maintenance bypass switch are also lo-
cated at the bottom of the frame. The output voltage trans-
former is located inside the bottom of the frame. A fully loaded
MiniFrame is depicted in figure 1-1. A MasterFrame with
factory installed MIM and RIM, and empty power and bat-
tery module bays is depicted in figure 1-2.
