ICT STANDARD DUAL BUS DISTRIBUTION PANELS
The ICT Dual Bus Distribution Panel provides two 100A (peak)
bus inputs with six independent output channels per bus in a
compact 1U high chassis for 19 inch rack mounting. Over
current protection for each output is available on the front
panel in two configurations; with 80VDC rated blade style fuses,
or with 65VDC user insertable magnetic-hydraulic circuit
breakers.
Each bus can accommodate a supply voltage from 10VDC to
60VDC, either positive or negative polarity, with a peak input
current of 100A to be distributed at 25A maximum on each of
the 6 output channels. Each channel has independent over
current protection.
Fuse status is displayed by an LED indicator located over each
fuse, while breaker trip status is indicated locally by the rocker
handle position. Form-C alarm output contacts (C/NO/NC) are
provided on the back panel for each bus to indicate that a
channel fuse or breaker has opened.

WARNING
Risk of serious personal injury or damage to equipment and
property! Always observe the following:
Use an appropriately rated over-current protection device
and disconnect switch in line with the main battery
connections to the panel
Shut off or disconnect all dc power sources before
connecting or disconnecting any wiring
Use wire and connectors rated for the maximum load
current and size of fuse or circuit breaker, and keep cable
lengths as short as practical
Carefully observe wiring polarity when making input and
output connections
Securely tighten all connections
CAUTION
Risk of personal injury or damage to equipment! Always
observe the following:
Install unit in a restricted access location (such as
equipment rack) to limit unintentional contact with
terminals and wiring
Ensure the total power consumption of the loads does not
exceed the 100A (peak), 80A (continuous) rated capacity of
each power bus
Ensure load current through each output channel does not
exceed 25A maximum, or 20A continuous
Do not block air inlet or outlet openings in the panel sides
INSTALLATION
Inspect your distribution panel to ensure it was not damaged in
shipping, and has all accessories:
4 black plastic boots to insulate main dc power
connections (shipped with unit)
4 M8 size nut/washer/split-washer sets for high
current bus connector studs (shipped on unit)
2 three pin alarm output connector plugs (shipped on
unit)
8 ICT-BLP Breaker blanking plugs (ICT200DB-12 only)
To complete the installation you will also need appropriate
fuses (FKS-ATO type) or circuit breakers (available from ICT) for
each distribution channel you plan to use. Twelve 15A 80VDC
FKS-ATO blade fuses are shipped with each ICT200DF-12 panel,
while circuit breakers need to be ordered separately from ICT
per the following list for use on the ICT200DB-12 panel:

For 12V and 24V systems standard 32VDC ATO style blade fuses
may be used, with current ratings up to 25A. These fuses are
widely available from multiple manufacturers.
Mount the Dual Bus Distribution Panel in a 19 inch equipment
rack, using standard rack mounting hardware. (Not provided)
On breaker equipped models install appropriately rated circuit
breakers and blanking plugs in desired channel locations by
carefully inserting a breaker so that its mounting tabs securely
snap into the front panel. Breakers are not removable once
inserted.
On fuse equipped units change any channel fuses requiring
different current ratings. (Up to 25A max)
Bond the panel chassis to the rack system ground, connecting a
ground wire with ring tongue to the back panel ground stud. (8-
32 thread)
Connect Bus A loads to each output channel using suitable wire
(10AWG max) sized for the fuse or breaker installed on the
channel, stripping 10-11mm of insulation and firmly clamping in
the Bus A channel 1 to 6 output connectors by tightening the
clamping screw. Note which load is connected to each channel,
for future reference.
Repeat for the Bus B loads if required. The unit may be
operated with either Bus A or Bus B powered, or both.
NOTE!
All channel RTN lines, and the main high power Bus A and Bus B
RTN terminals are common, and tied to a single internal Return bus.
Bus A and Bus B inputs can be wired to a different dc voltage (10 to
60Vdc) of either polarity, but must share a common RTN voltage,
normally at earth potential.
It may be possible to measure a voltage on the output terminal(s)
even if the breaker or fuse is open. This is normal operation. The
high-impedance detection circuitry may report a voltage reading
that is purely a signal voltage and does not support loading.
Connect the main Bus A RTN line to the external battery or
power supply return using wire and ring connectors rated for up
to 100A continuous current. Feed the wire through the plastic
insulating cap (supplied), and connect the ring tongue to the M8
RTN
stud, then securely fasten with supplied hardware. Slip the
insulating cap over the high current ring tongue and
RTN
stud
on the back panel to help prevent accidental contact with the
stud connection.
Connect the Bus A Input through a suitably rated disconnect
switch (
set in the open position
)
and a fuse or circuit breaker
rated for 100A max continuous operation to the external
battery or power supply output, using wire and connectors
rated for 100A continuous current. Feed the wire through the
plastic insulating cap (supplied), and connect the input ring
tongue to the M8
Bus A Input
stud, then securely fasten with
supplied hardware and slip the cap over the ring tongue and
stud to help prevent accidental contact with the input stud
connection.
Repeat input wiring for the Bus B input, its power source and
over current protection device, if the Bus B outputs are to be
