Initial Inspection Perform a quick physical check on the unit once it has been taken out of the box to confirm it has not been damaged in shipping, and then check for the included parts and accessories to make sure they are present. Your Digital Series unit comes complete with: • AC input wire clamp input connector plug (3pin), and 7 pin REMOTE connector plug • DC output bus bar cover and mounting hardware (installed) • Three Bus bar bolts with locking nuts for output wiring • Two rack mounting ears and hardware to mount to the power supply chassis (installed) • Instruction Manual 6 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). Pin Number 5 Name Common 6 NO 7 NC Note Alarm Output common Alarm Output normally open contact (0.5A 125Vac max) Alarm Output normally closed contact (0.5A 125Vac max) 3.

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’). 3. Turn the unit’s Power Switch to the ON position. 4. In the Control Panel menu, scroll to the Parallel Settings screen and press Enter. 5. Scroll to the Parallel Mode setting and press Enter. Scroll and choose Standalone as the parallel mode setting, then press Enter. 6. The unit is now configured as a Standalone unit. If the unit was previously configured as a Slave unit, the System Settings Control Panel screen will now be unlocked. Note that when the Parallel Mode setting (Standalone/Master/Slave) is changed to a different setting on a unit, the DC Output of that power supply will automatically be turned OFF if it is currently enabled. The user will need to verify the output voltage/current settings, then manually enable the output. 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. 1. 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. 3. Enter your user name and password. The default Administrator user name is admin, and there is no password by default. 4. Once connected, the Status page will appear in your browser window. 24 5.1. System Status This page provides information on model number, hardware version, input voltage, DC output enable status, output voltage, output current (of unit, and output of total system and number of parallel units if connected), and alarm conditions. The device name can be changed in the Device Setup page. 5.2. Device Setup This page allows you to change the DC output settings, and configure the parallel operation settings of the power supply (if applicable). DC Output Status: Controls and indicates the output status of the power supply. • The output ON/OFF button will enable or disable the DC output and optional battery LVD contactor. • The Auto-Restart button will disable the supply output for the Restart Delay period (see below) when clicked. This feature can be useful when equipment powered by the unit must be remotely power cycled to reboot operation. NOTE: Using the ON/OFF or Auto-Restart button on a unit configured as a Parallel Master will cause all Parallel units in a set to disable their output, but will have no effect if used on a unit configured as a Parallel Slave. Output Settings: Used to change the output voltage or current limit of the supply. To save any changes to the output settings, click on Save Settings at the bottom of the page. 25 • Output Voltage: This field sets the DC output voltage of the power supply within the allowable range. • Current Limit: This field sets the DC output current limit of the power supply within the allowable range. Device Name: Enter a unique name for the power supply if desired. Auto-Restart Delay: Set delay time (5 to 240s) that output will remain off when output is remotely disabled using the Auto-Restart button. The unit will then automatically restart after the Restart Delay period. Parallel Operation: Configure the unit as the master, or a slave unit within parallel connected sets. Also set a unique ID number for each parallel unit (required) and enable parallel slave unit alarm e-mails if desired. See section 4.4 Advanced Parallel Operation with TCP/IP Ethernet Option for more information. 5.3. Battery Backup This page is only available if the power supply has the “Battery Backup” LVD option “B” installed. This page allows you to configure the backup options of the power supply. To save any settings changes, click on Save Settings at the bottom of this page. 5.3.1. LVD (Low Voltage Disconnect) SETTINGS: Disconnect Voltage: If the battery voltage drops below the value in this field, the battery relay will open and disconnect the battery.

RESET COMMUNICATIONS Pressing the Reset button will reset the communications controller on the power supply without interrupting DC power to the output terminals. All existing settings will be maintained. 31 5.7.2. RESTORE FACTORY DEFAULT SETTINGS Pressing the Restore button will restore ALL communications and alarm settings to the original factory default values, including all passwords. If you only want to reset the IP address and Administrator password of the power supply, see the Administrator Password / IP Address Reset section. 5.7.3. SEND TEST E-MAIL Pressing the Send Test E-mail button will send test e-mail to the specified recipient using the e-mail settings on the Network Setup page. 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://188.8.131.52:8000 for IP Address 184.108.40.206, 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 email@example.com, replacing cell number with your cell phone number. Here are some address formats for other mobile phone providers: AT&T firstname.lastname@example.org Verizon email@example.com T-Mobile firstname.lastname@example.org 34 email@example.com Virgin Mobile Nextel firstname.lastname@example.org Bell Mobility email@example.com Rogers firstname.lastname@example.org Telus email@example.com 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.
