Breakers and Fuses
CAUTION: SIGNIFICANT EXTRACTION FORCE IS REQUIRED TO REMOVE DISTRIBUTION
DEVICES DUE TO THE CONTACT PRESSURE REQUIRED FOR HIGHLY RELIABLE , LOW -
TEMPERATURE RISE CONNECTIONS .
Up to six distribution busses, arranged into three sets of t o, can be configured
to receive plug-in breakers or plug-in fuse holders from the front of the Flatpack2
-48V 150A system. Plug-in positions are like ise grouped into a maximum of
three sets of t o positions, ith each set stacked vertically and oriented
horizontally.
Do not use any type of clamps, pliers, or other hard tools to remove distribution
devices as the housing may be cracked by excessive force. Damaged distribution
device represent an operational hazard and should never be used.
Figure 11 - Plug-in Disconnect Device Positions (2B 4L shown)
Plug-in Breakers
Auxiliary contact circuit breakers are standard over-protection devices used
this distribution. All breakers are connected to system alarming so that an
open breaker ( hether tripped or manually placed in the OFF position) triggers
a “Load Distribution Alarm” in the Smartpack controller. Breakers should be
removed from any unused positions to prevent nuisance alarms. Single-pole
circuit breakers rated up to 100A can be installed. Each set of positions also
accepts a t o-pole breaker rated up to 175A.
Plug-in Fuse Holders
As an alternative to plug-in circuit breakers, plug-in fuse modules may be
installed. The same considerations regarding insertion and removal of
breakers should be observed.
A plug-in fuse assembly consists of three main parts: A fuse, an alarm fuse
indicator, and a plug-in module. If the main fuse element opens, the alarming
fuse also opens, giving a visible indication of a fault condition; a signal is then
sent via the Smartpack alarm board that activates the remote system
monitor. The alarming fuse must be replaced henever a ne main fuse is
required. A fuse holder may be removed and inserted into the plug-in module
at any time; it is not necessary to remove the plug-in module to replace the
fuse.

the alarm may not signal properly hen a device opens.
To install plug-in breakers or fuse-holders for LOAD:
1) Remove the t o scre s holding the front cover in place using a Phillips
scre driver.
2) Orient the “LINE” and “LOAD” bullets to the correct bus. The leftmost
breaker set (next to the Smartpack controller) has LINE to the right
and LOAD to the left; the actuator turns ON to the left. The other
positions have LINE to the left and LOAD to the right; the actuator
turns ON to the r ght.
To install plug-in breakers or fuse-holders for BATTERY (if used):
1) Connect the battery alarm ire to the device’s normally closed (NC)
alarm pin.
2) Orient the “LINE” and “LOAD” bullets to the correct bus. The battery
breaker set (next to the Smartpack controller) has LINE bus to the right
and its LOAD bus to the left; the actuator turns ON to the left.
Securely insert device into the receptacles.
3) Remove fuses and turn breaker actuators OFF until system turn-up.

CAUTION: D O NOT CONNECT BATTERIES UNTIL SYSTEM TURN - UP . F OLLOW THE
CHECKLIST PROVIDED FOR THE PROPER PROCEDURE .
Every distribution configuration of the Flatpack2 -48V 150A system features t o
battery termination points. When vie ed from the rear, the battery bus landings
take up the one of the rightmost positions of the distribution section, just to the
left of the Smartpack alarm board. A label reading “BATT (-)” appears directly in
front of the landings.
There are t o possible configurations for battery connections: With breaker
positions or ithout breaker positions.
If breaker positions are utilized, the battery busses take up the rightmost
position hen the system is vie ed from the rear. The corresponding breaker
positions are located to the right of the Smartpack controller at front (leftmost
position hen facing the front of the system).
NOTE: Battery breakers turn ON to the left and OFF to the r ght.
If there are no breakers installed, the battery busses take up the position just to
the left of the bus ith breaker positions and to the immediate right of the
return bus. In this case, the rightmost busses may be used for load output. In
every case, make sure to check the labels before connecting batteries to the
system.
