iii
CAUTION
Risk of personal injury or damage to equipment and
property. Always observe the following:
•Use wire and connectors rated for the maximum load
current and size of fuse or circuit breaker in accordance with
NEC Section 210.20(A) and keep cable lengths as short as
practical.
•Install unit in a restricted access location (such as an
equipment rack) to limit unintentional contact with terminals
and wiring.
•Keep sources of moisture away from unit.
•Ensure all breakers are in the "OFF" position before
connecting or disconnecting wiring.
•Do not energize the unit before the chassis ground is
connected.
•DC-AC Inverters should not be connected to the outputs of
any ICT Distribution Series panel. DC-AC Inverters create
significant inrush current and may damage the circuitry or
interfere with the operation of power distribution panels that
they are connected to. Connecting an inverter in this way
may void the product warranty. ICT recommends connecting
a DC-AC inverter to the battery bank.
NOTICE
Risk of damage to equipment, environmental hazards, loss
of data and other undesirable consequences. Always
observe the following:
•The unit must be properly handled, mounted, and installed.
•Do not block air inlet or outlet openings.
•Due to environmental factors which are common at outdoor
communications sites, power surges from lightning strikes,
electrostatic discharge, and utility power feeds can occur.
These surges can damage connected equipment.
•Third-party surge suppression devices must be utilized to
protect AC input power feeds, and exposed DC power
conductors and data cables. To provide optimal protection,
these protection devices should be installed at both ends of
the exposed conductor, in close proximity to installed
equipment.
•Consult with manufacturers of surge suppression devices to
select appropriately rated protection device(s) and proper
installation methods.
•ICT’s product warranty does not cover damage caused by
power surges and electrostatic discharge events including
lightning.

NOTE: Due to the breaker-detection circuitry internal to the unit, it may be
possible to measure a voltage on the terminal(s) with no load
connected, even if that terminal’s breaker is open circuit. This is
normal operation. The breaker-detection circuitry is a high-
impedance circuit, and while a voltage may be present on the output
terminal, it is a signal voltage and does not support loading. A load
device connected to the output will immediately pull this voltage to
zero volts.
Product Alerts
CAUTION
Risk of personal injury or damage to equipment and
property. Always observe the following:
•Ensure the total power consumption of the loads does not
exceed the 100 amps (peak) rated capacity of each power
bus.
•Ensure continuous load current through each output
channel does not exceed the 80% of the maximum output
ratings in accordance with NEC Section 210.20(A).

1.0 INTRODUCTION
The ICT Distribution Series 3 dual-bus DC distribution panel provides two
100 amps (peak) bus inputs; with six independently controlled and
monitored output channels per bus in a compact 1RU chassis for 19-inch
rack mounting. Overcurrent protection for each output is available on the
front panel with 65-volt DC rated, user-insertable, magnetic-hydraulic circuit
breakers that are orderable separately.
Each bus can accommodate a supply voltage from 10- to 60-volt DC, either
positive or negative polarity, with a peak input current of 100 amps to be
distributed at 25 amps continuous (16 amps continuous for 48-volt systems)
on each of the six output channels. Each channel has independent current
sensing, overcurrent protection, alarms, and output on/off control.
Remote monitoring and control are available through the integrated
security-protected Ethernet communications port on the back of the unit.
The unit has a built-in web server with an embedded web-based graphical
user interface (GUI) that can be accessed using any standard commercial
web browser. The GUI displays all panel information; allows full access to
channel configuration settings; provides remote channel on/off control; and
can be set up to send an alarm to user-defined e-mail accounts in the event
a fault occurs. The GUI can also be used to configure and download a data
log of up to 30 days of time-stamped event information. Full monitoring and
control are also available using an SNMP-based management system for
larger installations.
System voltage, system current, output channel current, breaker status, and
alarm input status can also be monitored onsite through the front display
panel. Breaker trip status is indicated locally by the rocker handle position
and front Bus Alarm LEDs. Form-C alarm output contacts (C/NO/NC) are
provided on the back panel for each bus to indicate all distribution panel
alarms, while five additional alarm inputs can be used to monitor other dry-
contact site sensors such as door/window opening, smoke alarms, water
detectors, etc.

2.7 Load Connections
CAUTION
Risk of personal injury or damage to equipment and
property. Always observe the following:
•DC-AC Inverters should not be connected to the outputs of
any ICT Distribution Series panel. DC-AC Inverters create
significant inrush current and may damage the circuitry or
interfere with the operation of power distribution panels that
they are connected to. Connecting an inverter in this way
may void the product warranty. ICT recommends connecting
a DC-AC inverter to the battery bank.
•Ensure that the combined current draw on the outputs does
not exceed the output capacity of the bus (100 amps).
•Leave breakers turned off until the software has been
configured (see Section 4).
Make connections to the load using wire and connectors appropriately rated
for the maximum output current capability of the unit.
An output (labelled OUT) and return (labelled RTN) are provided for each
channel.

Distribution Series 3 Dual Bus
855-314-002_Rev2.0_Instruction Manual
Page 7 of 46
Each bus provides six remotely controlled and monitored outputs, with front
panel overcurrent protection provided by hydraulic-magnetic circuit
breakers (see Section 2.8 for the installation instructions for the breakers).
The maximum current rating for each bus is 100 amps. Each output can
accept maximum current based on the bus voltage (see Table 4).
Table 4. Bus Output Capacity
Bus Voltage
Output Capacity
12 or 24 VDC
Up to 6 x 30 A peak output (25 A cont.)
48 VDC
Up to 6 x 20 A peak output (16 A cont.)
The unit may be operated with either Bus A or Bus B powered, or both.
Each bus may have independent polarity and bus voltage.
CAUTION
All output return (RTN) lines and the main Bus A and Bus B RTN
terminals are common and are referenced to a single internal bus
(RTN). Bus A and Bus B inputs can be wired to a different DC
voltage (10- to 60-volt DC) of either polarity. When used with
mixed-polarity voltages, e.g., positive 12 volts on Bus A and
negative 48 volts on Bus B, the two voltage sources must be
electrically isolated from each other. Not isolating the two voltage
sources for mixed-polarity applications will short circuit and
potentially damage connected equipment.
For each bus that is being used:
1. Locate the six outputs on the bus rear panel connector block.
2. Ensure that the breakers on the bus are turned off until the software
has been configured (see Section 4).
3. Verify the polarity of the bus.
4. Connect up to six external loads using appropriately rated wire
inserted and secured into the six cage-clamp output connector pairs
on the bus rear panel. The terminal will accept wires from 10–22
AWG.
NOTE: The outputs use normally closed relays.
2.8 Installation of Breakers
Install breakers in the 12 front locations of the panel by inserting into the
breaker openings ("On" or "I" facing up, "Off" or "0" facing down), ensuring
the breaker connector tabs securely seat in the breaker sockets. Leave the
breakers turned off until the software has been configured (see Section 4).

Distribution Series 3 Dual Bus

Page 8 of 46
CAUTION
If the breakers are not fully installed or are not installed "square"
they may cause intermittent power loss or unexpected behavior
for the load devices.
When installing load breakers, apply even pressure to the top and bottom
of the breaker to ensure proper engagement of the breaker with the rear
contacts (see Figure 3).
Figure 3. Installing breaker with even pressure
Applying pressure unevenly may result in misalignment of the contacts (see
Figure 4).
Figure 4. Installing breaker with uneven pressure
2.9 System Wiring Final Verification
1. Connect a 10/100 Base-T Ethernet cable to the RJ45 LAN port on
the rear panel to allow for remote monitoring and control of the unit.
NOTE: See the Network Monitoring and Control section for information on
configuring and using the built in GUI, e-mail, or SNMP functions
(see Section 4.7).

2. Check that all connections to the power distribution panel are
correct and properly tightened.
2.10 Input Connections
1. De-energize the DC source.
2. Connect the main Bus A RTN line to the power supply return using
wire and ring connectors rated for up to 100 amps continuous
current. Feed the wire through the supplied rubber insulating boot
and connect the ring terminal to the M8 RTN stud, then securely
fasten with supplied hardware. Slip the insulating boot over the high
current ring terminal and RTN stud on the back panel to help
prevent accidental contact with the stud connection.
3. Connect the Bus A INPUT through a suitably rated disconnect
switch (set in the open position) and a fuse or circuit breaker rated
for 100 amps max continuous operation to the power supply output,
using wire and connectors rated for 100 amps continuous current.
Feed the wire through the supplied rubber insulating boot and
connect the input ring terminal to the M8 Bus A INPUT stud, then
securely fasten with supplied hardware. Slip the boot over the ring
terminal and INPUT stud to help prevent accidental contact with the
stud connection.
4. Repeat input wiring for the Bus B INPUT, its power source and
overcurrent protection device, if the Bus B outputs are to be used.
5. Energize the DC source and close any disconnect switches.
2.11 Software Configuration
Configure the software (see Section 4).
2.12 Energize Loads
Switch on the output breakers 1 to 12 (if installed) to energize any loads
connected to the distribution panel outputs.
2.13 Mixed Polarity or Voltage Installation
All output return (RTN) lines and the main Bus A and Bus B RTN terminals
are common and are referenced to a single internal bus (RTN). Bus A and
Bus B inputs can be wired to a different DC voltage (10- to 60-volt DC) of
either polarity. When used with mixed-polarity voltages, e.g., positive 12
volts on Bus A and negative 48 volts on Bus B, the two voltage sources must
be electrically isolated from each other. Not isolating the two voltage
sources for mixed-polarity applications will short circuit and potentially
damage connected equipment.

3.0 OPERATION: FRONT DISPLAY PANEL
Energize each bus by closing the main external breaker or disconnect
device on the bus input lines. Check that the distribution panel front graphic
display powers up. The Distribution Series 3 will start up and operate at the
factory default settings when DC power is connected, generally requiring no
further set up or adjustment for basic operation.
3.1 Graphic Display
Use the front display screen and two interface buttons on the front panel to
monitor the bus voltage, total bus current, network status, channel output
status of the selected bus and the alarm status of the external monitored
devices.
Figure 5. Front Control Interface
NOTE: The LCD backlight will activate when pressing either "Output Select"
button and will turn off after approximately 15 minutes of inactivity.
Bus A "Output Select" Button: Use to scroll through the Bus A display
screens; or to switch to the Bus A main screen from Bus B.
Bus B "Output Select" Button: Use to scroll through the Bus B display
screens; or to switch to Bus B main screen from Bus A.
Holding either "Output Select" button for 2 seconds will return the display to
the main screen for that bus. Holding either "Output Select" button for 20
seconds will reset the password to the factory default (see Section 3.3).
3.2 Menu Structure

NOTE: While navigating using the A button, pressing B will take the user to
the Bus B main screen. Similarly pressing A while navigating using
the B button will take the user to the Bus A main screen.
3.2.1 Main Screen
The main screen will show the name of the unit — user configurable through
the graphic user interface (GUI), the bus being monitored (Bus A or Bus B),
the bus voltage, and the total bus current.
Other information will be shown depending on the operating state of the unit:
•The bus voltage will blink if the voltage exceeds the undervoltage
or overvoltage alarm thresholds.
•The total bus current will blink if the current exceeds the
overcurrent alarm threshold.
Press either "Output Select" button to move to the
Network Screen.
