2.2. Back-up Battery
An external lead-acid battery with the same nominal voltage as the power
supply may be connected directly in parallel with the output terminals, or to
the BAT terminal (on units with the LVD option “B”) to provide a DC
backup capability. Use appropriate wire, over current protection and
disconnect device as outlined in the Installation section. Your load will
then be powered from the external battery if the AC input power should fail,
and the battery will recharge from the supply output when the AC power
returns. Choose your battery size (Ahr capacity) so that it can provide power
to the connected loads for the duration of a typical loss of AC power.
For both battery configurations the external battery will be charged with a
constant current (the supply output current setting) until the float voltage
(supply output voltage setting) is reached, and then will be held at a constant
float voltage as long as the Digital Series supply is powered on.
WARNING!
Potential for personal injury, or damage to property and
equipment due to overcharging of the external battery!
The supply output voltage must be set to a voltage level suitable
for the external battery used. Check the float voltage rating of
your battery and set the supply output voltage accordingly
before connecting the battery to the system.
The battery may be charged at a rate up to the maximum output
current rating of the power supply. Ensure the battery used is
capable of being charged at this rate.
Heavily discharged batteries will initially be charged with a small trickle
current on LVD equipped units when connected to the BAT terminal. When
the battery voltage is greater than the LVD Reconnect voltage (user
adjustable) the internal LVD contactor will close connecting the battery to
the main power supply output and the load, allowing the battery to charge
and be maintained at its float voltage level. If the AC power fails during
normal operation the battery will remain directly connected to the output
through the LVD contactor and able to power the load with no delay or
transition time. As battery voltage falls to the LVD disconnect level (user
adjustable) the LVD contactor will open to help protect the battery from
excessive discharge. The contactor will re-close once the battery voltage
rises again to the LVD Reconnect threshold (user adjustable) due to
charging from either an external source, or when AC power is returned to
the power supply.
7
Note that during battery operation with AC power off the front panel display
and optional external communication ports will not be powered. Only the
battery LVD circuitry will be active.
2.3. Installation
The ICT Digital Series Power Supply is designed to be used in an industry
standard 1RU 19” rack mount cabinet or other restricted access location.
Insert the unit at the desired rack location, and secure the unit using standard
rack nuts and bolts (not provided). After the unit is mounted, connect load
and supply wiring as outlined in the steps below, referring to the back panel
drawing in Figure1 for connector locations:
(Figure 1 - Back Panel, “SBC” model shown)
1.
Connect the positive side of the load to the ”POS” busbar and
the negative side of the load to the ”NEG” busbar using
suitable wire and supplied hardware. Make sure to tighten the
busbar hardware to properly secure the wires.
2.
If applicable, on units with the Battery Backup (LVD) option
installed connect the POSITIVE of the backup battery to the
“BAT” busbar and the negative of the backup battery to the
“NEG“ busbar using suitable wire, over current protection,
disconnect device and hardware.
CAUTION!
The internal LVD contactor ties the “BAT” terminal to the power
supply “POS” output.
When using the LVD option in a positive ground system do not
ground the positive terminal of the battery. The system must only
have a single ground connection, normally located at the distribution
or load point. An additional ground connection at the battery will allow
current to bypass the internal LVD contactor preventing
disconnection of the battery during a low voltage event.
8
WARNING!
Battery current through the “BAT” terminal must not exceed the
maximum current limit rating of the Digital Series power supply.
Connect the “BAT” terminal to the external battery POSITIVE
using a suitably rated over current protection and disconnect
device.
Otherwise damage to the unit, load, battery, and personal injury
may occur if the battery is inadvertently connected in reverse
polarity, or the output circuit is over loaded or shorted.
3.
Connect a chassis bonding wire to the ¼ inch ground stud
located on the back panel, if required, using 14AWG/1.5mm2
or larger wire to bond the power supply chassis to the
external rack system for the installation.
4.
Connect appropriately rated non-energized AC power wiring
to the removable AC input connector terminal plug. (AC line
or neutral to either outer connection, safety ground to the
middle pin) using 14AWG/1.5mm2 or larger wire.
5.
Connect the unit to a properly grounded non-energized AC
source capable of handling the rated Digital Series input
current. The building supply circuit must have a short circuit
protection breaker rated 20A or less.
6.
Energize the AC source, and push the front panel “ON”
switch to power up the unit, then close the backup battery
disconnect device if an external battery is used.
7.
Disconnect all power sources (AC input, output battery or
back-up battery) before attempting any service activity.
2.4. Remote Control and Monitoring Connections
The following connections may be made to the “REMOTE” connector on
the back panel for the following remote control and monitoring
functionality:
CAUTION!
9
Ensure unit is off and power is disconnected prior to making
connections to the REMOTE connector terminals to avoid
damaging the power supply or connected devices.
•
Connect external Remote Shutdown control lines (TTL
compatible signal) to the REM SD+ (pin 1) and REM SD- (pin
2) terminals of the “REMOTE” connector on the back panel if
external on/off control of the power supply output is required.
(Hi = output off, Lo = output on) (Does not alter the state of the
Battery contactor on units with the LVD option)
•
Connect remote voltage sense lines (16-26AWG twisted pair)
from the REM SNS+ (pin 3) and REM SNS- (pin 4) terminals of
the “REMOTE” connector on the back panel to the external
load connections if required for tighter voltage regulation at the
load. (Default voltage regulation sense point is at the output
bus bars if Remote Sense is not connected).
•
To keep the remote sense lead voltage compensation accuracy
to within about 2% of the total load cable voltage drop, remote
sense lead resistance should be kept to below 0.5ohms each.
For example 15m (50ft) of 20AWG wire would be about
0.5ohms in resistance. Longer remote sense lead connections
can be made using larger wire sizes, or relaxing remote sense
voltage compensation accuracy expectations.
•
Connect external alarm monitoring input wiring to the Alarm
Output contacts on the REMOTE connector to enable the
internal Alarm relay contact closure to flag an external
monitoring system that the power supply has encountered a
fault condition. (See section 5.4 Alarm Setup, for details on
which fault conditions will trip the Alarm Output contacts).

4. SMART PARALLEL OPERATION
If your load requires more power than can be supplied by a single
ICT Digital Series power supply, two or more power supplies
(maximum 6) of the same output voltage rating can be connected in
parallel in a Master-Slave configuration to increase the power
available, provided the TCP/IP Ethernet Option is installed
WARNING!
Do not use the Battery Backup/LVD option “BAT” terminal on
units connected in parallel, as there is a risk that the potential
current could be higher than the rating of the internal low
voltage disconnect relay.
Otherwise damage to the unit, load, and/or personal injury may
occur if the battery output current through the BAT terminal
exceeds the rating for an individual supply.
CAUTION!
Do not connect power supplies of different output voltage
ratings in parallel, as this may cause damage to equipment or
connected load.
Up to six power supplies of the same output voltage rating can be connected
in parallel to provide up to six times the total output power capability. An
optional bus bar set (ICT-PAR) is available to simplify connection of two
units in parallel. When multiple power supplies are operating in parallel,
they should all be connected together through the RS485 SHARE interface
(included as part of the “Ethernet Option”), which will allow the units to
share output current more equally, and allow for external network
connection for the combined units using a single Ethernet port. One of the
units will operate as a Master, and the remaining units are Slaves. The Slave
unit’s settings will be controlled by the Master.
Each unit displays its own output current and voltage on the System
Status screen in the Control Panel menu.
If you are running a single, standalone power supply, the Parallel
Mode setting must be set to Standalone.
18
4.1. RS485 Interface Connector
The RJ-11 connectors for the RS485 serial interface are located on
the back of the power supply and are labeled SHARE “A” and “B”.
See figure 3. Parallel units must be connected together in a daisychain manner with a RJ-11 4-wire straight-through cable.. A short (4
inch) RJ-11 connector cable suitable for interconnecting stacked
power supplies is available from ICT, part number “ICT-JMP”.
(Figure 3 Back panel SHARE connections)
4.2. Configuring the Power Supplies for Parallel
Operation
Before connecting the power supplies together, they should all be
configured for parallel operation. To do this:
1.
Power each unit up independently. In the Control Panel menu,
scroll to the Parallel Settings screen and press Enter.
2.
Scroll to the Parallel Mode setting and press Enter. Scroll and
choose a parallel mode setting, then press Enter. One unit must
be configured as a Master, and the remaining units must be set
to Slave. If more than one unit is configured as a Master, the
units will not operate in parallel correctly.
Since the Slave units will be controlled by the Master, set the unit
you would like to use to set the Output Voltage and Current Limit
as the Master unit. You will be unable to set the Output Voltage
or Current Limit from any of the Slave units once they are
configured as Slaves.
3.
Scroll to the Device ID setting and press Enter. Scroll and choose
a unique device ID number for each unit, then press Enter. If
more than one unit is assigned the same device ID number, the
units will not operate in parallel correctly.
19
NOTE: Although not recommended, it is possible to connect up to six
Digital Series power supplies in parallel without using the TCP/IP
Ethernet option and the Smart Parallel feature. It is important that the
parallel-connected power supplies generally share the load equally.
In order to achieve this, the size and length of the connecting wires
should be sized properly and of the same gauge, and the wire
lengths between the power supplies should be virtually identical. To
ensure proper load balancing without using the Smart Parallel
feature, use a voltmeter to measure the output voltage of each power
supply with the load connected, and using the Intelligent Power
Control interface on the front of the Digital Series power supply,
adjust the output voltage level of each power supply until the outputs
are within +/- 1% of each other.
4.3. Connecting the Power Supplies in Parallel with
TCP/IP Ethernet Option Installed
20
WARNING!
Do not use the Battery Backup/LVD option “BAT” terminal on
units connected in parallel, as there is a risk that the potential
load current could be higher than the rating of the internal low
voltage disconnect relay.
Otherwise damage to the unit, load, and/or personal injury may
occur if the battery output current through the “BAT” terminal
exceeds the rating for an individual supply.
(Figure: 4 Back Panel Parallel Connections)
1.
After configuring each power supply for parallel operation, turn the
Power Switch on all units to the OFF position.
2.
Connect the positive terminals (labeled “POS”) of each unit together at
a common positive load point using the optional ICT-PAR parallel
straps. This will provide optimal current sharing between the units. See
figure 4.
3.
Connect the negative terminals (labeled “NEG”) of each unit together at
a common negative load point using the other ICT-PAR parallel strap.
4.
Using a RJ11 4-wire straight-though cable (Optional accessory part no.
ICT-JMP), connect the SHARE “A” terminal on the first unit to the
SHARE “B” terminal on the second unit. If there will be more than two
units operating in parallel, repeat this step for each unit, as shown in
Figure 4 above.
21
5.
Turn the Power Switch on all units to the ON position, no load
connected. The Parallel Settings screen in the Control Panel
menu on each unit will now display the number of units
connected together through the RS485 SHARE interface. If any
of the units were not configured correctly for parallel operation, a
“Parallel Configuration Error” warning will be displayed on the
Control Panel display.
6.
In the Master unit’s Control Panel menu, scroll to the System
Settings screen. The Output Voltage, Current Limit, and Output
Enable of all units are set here. The Output Settings screen on all
of the Slave units will be locked out.
4.4. Advanced Parallel Operation with TCP/IP
Ethernet Option
If the TCP/IP Ethernet option is installed, the following settings and
information are available on the Device Setup page: (see section 5)
Parallel Mode: This field sets the Parallel Mode of the power supply
to Master, Slave, or Standalone. The Parallel Mode can also be set
from the Control Panel.
Device ID: This field sets the unique Device ID (number between 0
and 5) for parallel operation of the power supply. The Device ID can
also be set from the Control Panel.
Send Slave Alarm Emails: If this box is checked while this power
supply is operating as Master unit, the Master will send out alarm
notification e-mails when an alarm occurs on a Slave unit. This
feature is useful if your site has a limited number of Ethernet network
ports available at your site and you are unable to connect all of the
Slave units to the Ethernet network.
•
This box will have no effect if the unit is configured as a Slave or
Standalone unit
•
If this feature is enabled, check the Send E-mail boxes on the
Master unit’s Alarm Setup page for the alarms you wish to
receive e-mail notifications for
Parallel Errors: Displays any errors or alarm conditions related to
the RS485 interface that are currently active.
22
4.5. Changing a Power Supply Back To a Standalone
Unit
To release a unit from parallel operation and change it back to a
Standalone unit, do the following:
1.
Turn the Power Switch on all parallel units to the OFF position.
2.
Disconnect the connections to the positive terminal (labeled
“POS”), negative terminal (labeled “NEG”), and RS485 interface
(labeled “A” and B’).

5. TCP/IP WEB BASED UTILITY OPTION
When ordered with the TCP/IP Ethernet option “C”, this power supply
will be equipped with an embedded Web server that allows you to
monitor the status of the power supply, and change the power
supply’s settings and configuration when the unit is powered from the
AC line. (Note: Remote communication is not supported during
battery backup mode when power is being supplied from an external
battery.)
The advantage of an embedded Web server is that it provides an
interface to the power supply that can be accessed through a
23
standard Web browser on a network-connected computer. There is
no additional software to install or configure.
Follow these steps to access the Digital Series embedded Web
server from a browser. The recommended web browsers to use with
this power supply are Microsoft Internet Explorer, Mozilla Firefox or
Google Chrome.

2.
Start your Web browser.
Enter the IP address of the power supply in the location/address
field of the browser.
If the power supply is connected to a network with a DHCP server,
the power supply will be assigned an IP address automatically. The
current IP address of the power supply can be found on the Network
Status screen (see the Control Panel Menus section for more
information). If the power supply is not connected to a network with
DHCP, it will use a default IP address of 192.168.0.181.

5.8. Router Configuration
This section explains how to set up the embedded Web server
interface behind a router and enable remote access to the panel over
the Internet.
A router allows multiple PCs to share a single Internet connection. To
enable access to the Web server over the Internet, you will need to
configure your router to forward incoming remote data to the local IP
address of your power supply.
The following steps use a Linksys WRT54G router as an example:
1.
Log in to your router and go to the port-forwarding screen. In the
Linksys WRT54G, this is located in the Applications and Gaming
tab. The location of port forwarding may be different on other
routers (consult your router manual for instructions).
2.
To configure HTTP forwarding, following these steps:
a. Enter a unique name in the Application field.
b. Enter the HTTP port number that the power supply is using in
the Start and End fields. If you are using the default power
supply port settings, the port number is 80.
c. Select Both under Protocol (TCP and UDP).
d. Enter the local IP address of the power supply (e.g.
192.168.0.181) in the IP Address field. The current IP
address of the power supply can be found on the Network
Status screen (see the Control Panel Menus section for more
information).
e. Check Enable, and then click on Save Settings.
32
NOTE: Many ISP’s block access to port 80. If your ISP does block
port 80, you will need to change the HTTP port the panel uses from
80 to something else, such as 8000. Valid port numbers are in the
range of 1 - 65535. See the Network Setup section for instructions on
how to change the power supply network ports.
You will also need to change the HTTP port number from 80 to
something else if your local network already contains another device
using port 80 such as another panel or a Web server.
3.
To configure HTTPS forwarding, repeat steps 2a – 2e with the HTTPS
port number that the panel is using. If you are using the default panel
port settings, the HTTPS port number is 443.
4.
To set up your router to allow remote panel firmware upgrades, repeat
steps 2a – 2e with the UDP port number that the panel is using. If you
are using the default panel port settings, the UDP port number is 9393.
Firmware upgrades can still be applied locally if this step is skipped.
5.
Before you can access the panel over the Internet, you will need to
know the WAN IP address of the router, which is assigned by your ISP.
With the Linksys WRT54G router, this information is available in the
Status tab, listed as “IP Address”.
33
NOTICE! If you are using a Dynamic IP address, your WAN IP
Address may change from time to time without warning, depending
on your ISP. You may want to obtain a Static IP address from your
ISP, which will be more convenient to use to access the panel from a
remote location. A Static IP address is a fixed IP address that will not
change. Alternatively, if a Static IP address is not available, you can
use a Dynamic DNS service such as DynDNS.com (see
www.dyndns.com).
To access the panel over the Internet, type the WAN IP Address of the
router in the location/address field of your browser, followed by a colon
and the HTTP port number that the panel is using (e.g.
http://209.123.10.33:8000 for IP Address 209.123.10.33, Port 8000).
The Web server panel should then appear, as shown below:
5.9. Text Message Alarm Notifications
The Digital Series Power Supply can send text message alarm
notifications to a cell phone by sending the alarm e-mail to an
address at the mobile phone provider. On the Network Setup page,
enter the address for your phone in one of the “To” E-mail Address
fields. For example, to send a text message to an AT&T phone, enter
cellnumber@txt.att.net, replacing cell number with your cell phone
number.
Here are some address formats for other mobile phone providers:
AT&T
cellnumber@txt.att.net
Verizon
cellnumber@vtext.com
T-Mobile
cellnumber@tmomail.net
34
cellnumber@vmobl.com
Virgin Mobile

5.10. Troubleshooting
I am unable to access the embedded Web server:
• Check that you are using the correct IP address to access the
power supply’s embedded Web server by viewing the Network
Status screen on the Control Panel display (see the Control
Panel Menus section for instructions on how to access the
Network Status screen). The IP address for the power supply
may have changed if DHCP is enabled.
•
If the Network Status screen on the Control Panel display shows
Network Not Connected, check the network cable connections to
the power supply and the network.
•
Ensure that you are using the correct type of network cable. An
industry standard "crossover" cable should be used for
connecting directly to a computer, and a “straight-through” cable
should be used for connecting to a network.
•
Ensure the network card settings on your computer are
appropriate for accessing the IP address of the power supply. To
access a power supply with the default IP address of
192.168.0.181, typical network settings for your computer are:
o IP Address: 192.168.0.100
o Subnet Mask: 255.255.255.0
o Gateway: 192.168.0.1
•
If the HTTP port of the power supply has been changed, you
must append the port number to the URL used to access the
panel. See the Administrator Password / IP Address Reset
35
section for instructions on how to reset the port number to the
default setting.
I am not receiving e-mails from the power supply:
•
On the Network Setup page, ensure that the SMTP Server field is
entered correctly. The SMTP Port should be set to 25 for most
servers.
•
There must be valid e-mail addresses in the "From" E-mail
Address and "To" E-mail Address #1 fields. Do not enter more
than one e-mail address in each field.
If your SMTP server requires authentication, ensure that the
SMTP User Name and SMTP Password fields are entered
correctly. If no authentication is required, leave these fields blank.
•
•
Verify your e-mail settings by going to the Maintenance page and
clicking on the Send Test E-mail button to send a test e-mail. The
Send Test E-mail page will display an error message if the power
supply unable to send the e-mail.
•
On the Alarm Setup page, ensure that the Send E-mail checkbox
is checked for alarm conditions you wish to receive notifications
for.
I forgot my password for the embedded web server:
•
See the Administrator Password / IP Address Reset section for
instructions on how to reset the password.
I forgot my password for the Control Panel Menu:
•
36
See the Control Panel Menu Password Reset section for
instructions on how to reset the password.
