Connections
Overview
DC (load) distribution panels offer either fuses (US or DIN styles) or
circuit breakers (US or DIN styles). Fuse panels are available with
protectors from 1 to 600 amps and circuit breaker panels are available
with protectors from 3 to 800 amps. Some of the larger protectors (100
amperes and above) have load monitoring shunts in each load protector
path. When using remote peripheral monitoring modules (RPMs) with
the Galaxy Millennium Controller, measurement of these loads is
available for history and sizing.
The dc distribution panels may be equipped with a ground return bar for
connecting the load returns internal to the cabinet, or external ground
return bars may be used.
All distribution panels except for the smallest GMT fuse panels may be
equipped with a low voltage load disconnect (LVLD) contactor for
load-shedding applications.
Each panel is equipped with an alarm card that communicates to the
controller any operated fuse or circuit breaker and provides a visual
LED that indicates an operated protector.
Note: Panels for dc distribution are white; battery connection panels are
blue.
Warning
Turn off dc breaker and remove dc fuses before making connections.
