INTRODUCTION 1.0

Gravitas X75 is an ultra-compact, integrated DC power system. The base system is a 1RU shelf holding up to three hot-swap rectifier modules. This system produces up to 1950 watts output at -54.4, +27.2 or +13.6VDC.

It can also be operated as a 2+1 redundant system with up to 1300 watts output. The expanded system consists of a base shelf plus an expander shelf with a 2RU total height. This system holds up to six rectifier modules with up to 3900 watts output; it can be operated as a 5+1 redundant system with up to 3250 watts output. Each rectifier module is cooled by a fan that operates at a speed which is a function of load and temperature.

There are up to five circuit-breaker protected DC outputs or up to 10 GMT fuse protected outputs on the base system. A battery string breaker and a low-voltage battery disconnect are standard features. The expander shelf comes with a ribbon cable and connectors to link the signals between the two units at their rear panels.

It also comes with bus bar links to parallel the rectifier output bus bars.

The base and expander shelves can also be operated as a battery backup, single feed power system (without load circuit breakers or fuses).

The remote access controller has LED visual indicators and Form C relay alarms. It is programmed by means of a remote PC web page display with communication by Ethernet LAN. Temperature compensated rectifier output is provided by means of an accessory TC probe. The X75 can be quickly installed by a qualified technician.

INSTALLATION & OPERATING MANUAL

Above J1 is a 4-way Phoenix connector type MCO.5/4-G-2.5.

This connector, designated J2, provides terminations for the auxiliary digital alarm input and the optional external temperature probe. The pinout for this connector is described in section

10.

To the left of J2 is the Ethernet TCP/IP connector (J3). This connection uses a standard RJ45

Network connector. It is used to connect either to a Local Area Network or directly to a PC with network connection, the latter using a standard cross-over cable.

The primary means of setting up the X75 unit is via it’s built-in WEB server, which is accessed using a WEB browser via this Ethernet TCP/IP connection.

At the right hand side of the base unit and also the expansion shelf are three IEC60320 C14 inlets. These provide individual AC input feeds to each of the 3 rectifier slots.

The X75 employs UNIPOWER Telecom Sigma Series rectifiers which operate from a

Universal 85-264VAC 50-60Hz single phase supply. The system is designed so that various single and 3-phase supply connections can be made. For example, in the U.S. it might be desirable to connect each rectifier between two 120VAC phases; in which case each rectifier is operating at 208VAC.

IMPORTANT NOTE: DO NOT CONNECT THE UNIT SUCH THAT MORE THAN 264VAC

WILL BE PRESENT BETWEEN THE LIVE AND NEUTRAL TERMINALS OF ANY ONE

INLET SOCKET. SUCH CONNECTION MAY BE HAZARDOUS, WILL DAMAGE THE UNIT

AND INVALIDATE THE WARRANTY.

MAKING CONNECTIONS TO THE X75

10.1

DC Load Connections

The DC load distribution connections at the rear left of the unit are clearly marked as follows:

10.1.1

Circuit breaker option.

For each load circuit there are two terminals marked V1, V2, V3, V4 and V5 respectively for the DC ‘feed’ and two marked RTN for the DC ‘return’.

10.1.2

GMT Fuse option.

For each load circuit there is one terminal marked V1 through to V10 respectively for the DC ‘feed’ and one marked RTN for the DC ‘return’.

Note that in the case of -48VDC system the ‘feed’ terminals are at a negative potential with respect to the ‘return’ terminals. In the case of +24VDC and +12VDC systems the ‘feed’ terminals are at a positive potential with respect to the ‘return’ terminals.

When connecting to the DC load terminals it is important to ensure that the cables used are adequately sized to carry the expected load current for the circuit in question.

The maximum current rating for the individual load terminals is 32A, but where long cable runs to the load are to expected care should be taken to avoid unacceptable cable voltage drop; this is most likely occur at currents in excess of 20A if only a single feed and return cable are employed. It is recommended that for circuits where a 20A or greater breaker is fitted pairs of feed and return cables are installed.

10.2

Alarm Relay and Battery Temperature Probe Connections – J4

Connection to the Form-C alarm relay outputs is made through a 15-way spring clamp terminal connector. There are a total of 4 relay outputs with Normally Open, Normally

Closed and Common Contacts available for connection. The individual relays contact sets are fully isolated and may be floated from GROUND by up to 100V. Maximum contact current and voltage are 1A and 30V (DC or AC) respectively.

The alarm relays are designated K1 to K4. K1 and K2 are pre-programmed for MAJOR and

MINOR alarm conditions by default. K3 and K4 are not programmed for any alarm function.

The function of each alarm may be programmed using the

Alarm Configuration

INSTALLATION

The X75 can be mounted in either 19” or 23” racks by using the supplied brackets. Mount it from the front of the rack using the correct offsets to align with existing rack-mounted equipment. Once mounted in the rack the following connections must be made with the unit switched off.

CAUTION: Re-read the Safety Warnings and Precautions in Section 3. All power should be OFF for the input and output loads before making connections. Connection of the X75 chassis to frame ground should be made first. If the X75 has been turned on before installation connections, it should be turned off and given a 5-minute waiting period for all internal energy storage capacitors to be discharged.

11.1

Input AC Power Connection

A 3-wire AC power line should be connected to the input IEC connectors but not plugged into the AC power source. The line, neutral and ground connections should be carefully observed when making the AC connections. The AC line cord should be sized to safely carry

15 amperes AC each, minimum.

11.2

Checking Outputs

Turn all output circuit breakers to the OFF position and/or remove all fuses from the GMT fuse-holder. With no loads connected and without the battery connected, plug in or connect the AC input cords one at a time to the AC power source. Be sure to use the correct AC voltage for the rectifier inputs. Using a volt meter measure the DC voltage reading across the

–VO and +VO bus bars at the rear of the unit. The voltage should be approximately 54.4,

27.2, or 13.6VDC (depending on model), which is the factory setting. One by one, turn each output circuit breaker to the ON position and/or insert a GMT fuse and measure the DC voltage across the corresponding output terminals. The voltage should again read approximately 54.4, 27.2, or 13.6 volts. After each output is measured, turn OFF that circuit breaker and/or remove the GMT fuse and turn ON and/or insert a fuse in the next one. After measuring the last circuit, turn off that breaker and/or remove the GMT fuse and make sure that all output breakers are in the OFF position and/or all fuses are removed. Next, unplug or disconnect the AC input power source. Before touching any terminals wait 5 minutes for the internal storage capacitors to discharge.

11.3

Controller Section Operation and Settings

At this point, before the final installation connections, read section 12 covering Controller setup. Next, make any required signal connections, controller adjustments, temperature compensation adjustment and alarm enabling settings.

WARNING: Remember to take precautions each time the system is turned on and also when connecting or disconnecting the battery. Remember that the battery presents an energy hazard at its terminals. Also remember to allow 5 minutes for internal capacitors to discharge after disconnecting the AC input power and the battery.

INSTALLATION & OPERATING MANUAL

11.4

Connection to Loads

With input AC power unplugged, the battery disconnected and no other power sources connected to the loads, make sure that all load circuit breakers are set to the OFF position and/or all GMT fuses are removed. Connect load wires to each set of output terminals, one at a time. Note that the front panel breaker and fuse numbers directly correspond to the output terminal numbers. Be sure to connect the polarities correctly.

11.5

Connection to Battery

WARNING: Improper polarity of the battery connection may damage the power system. Take precautions when installing the battery and note that the battery cables are “hot” (live) and present an energy hazard.

With AC input unplugged, remove the three rectifier modules from the system chassis. Make sure all load circuit breakers are in the OFF position and/or all GMT fuses removed. Set the battery circuit breaker to the OFF position. Carefully connect the battery cables to the DIN-

Rail battery terminals shown in Figure 2 while observing the correct polarity.

Note that until AC power is applied to the system the controller will not activate the LVD contactor.

11.6

System Turn-On

Perform the following operations:

Set the battery and all load circuit breakers to the OFF position.

For systems with GMT fuse distribution remove all fuses if already installed.

Plug in the rectifier modules.

Connect the AC power cables to the AC source.

Check that the green LED on the front panel has lit. After approximately 20 seconds for initialization the MAJA LED at least will light. The RFA LED may also light, dependent on the number of rectifiers installed at the time.

Set the battery circuit breaker to the ON position. Then set the load breakers to the

ON position and/or insert the GMT fuses.

After approximately 5 seconds the status of various alarm LEDs will change, dependent on the number of rectifiers installed.

Using the WEB browser interface described in section 12 it is now possible to check overall system status for correct operation.

Manual No. X75M-5

08/12 X75-man

X75 SERIES

INSTALLATION & OPERATING MANUAL

In particular, it is important to ensure that the load current reading does not exceed the maximum capacity of the installed rectifiers or, where N+1 operation is required, the maximum capacity of one less than the total number of rectifiers installed. Note also, that the system should have been sized so that a proportion of the available rectifier capacity is allocated for battery charging. Where N+1 redundant operation is used the additional ‘spare’ rectifier will normally provide this current.

IMPORTANT NOTES: a) It is not possible to start the system by connecting the batteries alone. b) During the 30 seconds initialization period the system bus voltage will be at the factory preset level of the rectifiers. Nominally 54.4V, 27.2V or 13.6V depending on system voltage. After this period the internal controller will lower the output voltage by approximately 15% in order to limit current flowing to the batteries. During a following period of approximately 30 minutes the controller will ramp the system voltage up to the correct float voltage as determined by the temperature compensation algorithm.

USING THE CONTROLLER WEB BROWSER INTERFACE

The X75 is provided with a built-in WEB server which can be accessed through the TCP/IP Ethernet port using a WEB browser.

The WEB server employs Java Applets to continually scan system parameters and update the WEB page data. These same Applets return programming data to the X75 when set-up changes need to be made.

The WEB server communicates with the browser using HTTP on IP Port 80 and the Java Applets on IP Port

8888. If any firewall or proxies are configured on the LAN that the X75 is connected to it is important to ensure that these ports are open, otherwise the X75 will not respond.

Note also that a genuine Java engine must be installed on the browser PC. The latest version can be downloaded and installed for free from

www.java.com

The X75 has various network programming capabilities which allow it to be connected to almost any configuration of IP network.

The default network settings that the X75 is shipped with are:

IP Address

Subnet Mask

– 192.168.0.200

– 255.255.255.0

All pages served by the X75 built-in WEB server consist of two frames; a ‘navigation’ frame on the left hand side and an ‘information/programming’ frame which occupies the majority of the browser window.

The buttons in the ‘navigation’ frame can be used at all times to jump between the various pages. Clicking on the UNIPOWER Telecom logo at the top will navigate directly to the UNIPOWER Telecom WEB site www.unipowertelecom.com

Each of the blocks of information in the ‘information/programming’ frame is a Java applet. In some cases these applets simply collect information from the X75 and presents it on-screen, in other cases the applets contain data entry fields for uploading programming information to the unit.

DESCRIPTION

Gravitas X75 is an ultra-compact, integrated DC power system.

The base system is a 1RU shelf holding up to three hot-swap rectifier modules. This system produces up to 1958 watts output at -54.4, +27.2 or +13.6VDC. It can also be operated as a 2+1 redundant system with up to 1305 watts output. The expanded system consists of a base shelf plus an expander shelf with a 2RU total height. This system holds up to six rectifier modules with up to 3916 watts output; it can be operated as a 5+1 redundant system with up to 3264 watts output. Each rectifier module is cooled by a fan that operates at a speed which is a function of load and temperature.

The system can also be operated as a battery backup, single feed power system (without load circuit breakers or fuses).

The remote access controller monitors the system parameters and has alarms for system failures. There are six red LED alarms which indicate a failure: Major Alarm, Minor Alarm, Rectifier

Alarm, AC Input Alarm, Overtemperature Alarm and Overvoltage

Alarm. A green LED indicates that the controller is operating. Four

Form C relay outputs give alarms: Major Alarm, Minor Alarm,

Rectifier Alarm and AC Input Alarm. The controller is programmed by means of a remote PC webpage display. Communication is by Ethernet LAN with an SNMP (Simple Network Management

Protocol) alarm option. It also has provision for temperature compensated charging of an external battery using a supplied

TC probe.
