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.
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).
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.
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.
The Intelligent Power Control on the front of the Digital Series power supply allows you to view the status of the power supply, and modify the power supply settings. The Control Panel consists of the following: (Figure 2 Front Panel Display and Control) 3.1.

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.
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.
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.
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.
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.

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.
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).
