10.0 MAKING CONNECTIONS TO THE X100
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 Option A – 1-8 miniature circuit breaker.
Terminals marked 1-8 are used for breakers marked 1-8 respectively. Each
circuit has a FEED and a RETURN (RTN) connection. Terminals marked
9 and 10 are not used.
10.1.2 Option B - GMT Fuses.
Terminals marked 1-10 are used for fuse marked 1-10 respectively. Each
circuit has a FEED and a RETURN (RTN) connection.
10.1.3 Option C - 1-4 bulk circuit breaker.
To allow for the possibility of individual load circuits providing in excess of
30A this conguration uses two pairs of screw terminals linked together by
a small bus bar for each circuit. Terminals marked 1&2, 3&4, 5&6 and 7&8
respectively are used for Breakers 1 to 4 respectively. Terminals marked 9
and 10 are not used.
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
usedare adequately sized tocarrytheexpectedload current for the circuitinquestion.
The maximum current rating for the individual load terminals is 30A for options A
and B or 50A for option C, but where long cable runs to the load are expected care
should be taken to avoid unacceptable cable voltage drop; this is most likely to 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 tted pairs of
feed and return cables are installed.

INSTALLATION & OPERATING MANUAL
Manual No. x100-5a x100-man-Rev5a-0214.indd
10.2 Battery Connections
The X100 can be connected to two separate battery strings through the battery
two pairs of IMO ER35 terminal blocks. These terminals accept cables in the
range 10AWG to 2AWG. A minimum cable size of 4AWG is recommended when
employing only the internal 100A circuit breakers for protection (see section 8.2).
If a battery string is separately provided with a lower rated circuit breakers or fuse
then smaller gauge cables may be used as appropriate.
10.3 Alarm Relay and Battery Temperature Probe Connections – J2
Connection to the Form-C alarm relay outputs is made through the 18-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
relay contact sets are fully isolated and may be oated from GROUND by up to 100V.
Maximum contact current and voltage are 1A and 30V (DC or AC) respectively.
This connector accepts wire sizes from #28AWG to #10AWG.
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 by default and may be programmed using the Alarm
CongurationWEB page described later in section 12.
Connection of the supplied battery temperature probe, if required, is made using
terminals 1 and 2 of this same spring clamp terminal connector. An optional external
temperature probe may also be connected using terminals 3 and 4. Terminals 5 and
6 allow connection of a volt free contact closure input.

seconds for initialization the MAJA LED at least will light. The RFA LED
may also light, dependent on the number of rectiers installed at the time.
5. 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 rectiers installed.
Using the WEB browser interface described in section 12 it is now possible to check
overall system status for correct operation.
In particular, it is important to ensure that the load current reading does not exceed
the maximum capacity of the installed rectiers or, where N+1 operation is required,
the maximum capacity of one less than the total number of rectiers installed. Note
also, that the system should have been sized so that a proportion of the available
rectier capacity is allocated for battery charging. Where N+1 redundant operation
is used the additional ‘spare’ rectier 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 rectiers; 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 owing to the batteries.
During a following period of approximately 30 minutes the controller will ramp
the system voltage up to the correct oat voltage as determined by the temperature
compensation algorithm.
This ‘walk-in’ function can be disabled via the controller WEB interface if it not
required.

12.0 USING THE CONTROLLER WEB BROWSER INTERFACE
The X100 controller is provided with a built-in WEB server which can be accessed through
the TCP/IPEthernet port using a WEB browser. The WEB server employs JavaApplets to
continually scan system parameters and update the WEB page data. These same Applets
return programming data to the DSC1000 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 rewall or proxies are congured on the LAN that the
DSC1000 is connected to it is important to ensure that these ports are open, otherwise the
DSC1000 will not respond.
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. Please note that installing only a
browser plugin may not be sufcient for correct operation; so we recommend installing a
full Java package.
If the installed version of Java is 7u45 or earlier the following procedure “Setting up Java”
is not required for correct operation and cannot be implemented.
PLEASE NOTE THAT THEAPPLETS WILLNOT WORKWITH JAVAVERSION 7u51.

Setting up Java (7u60 or later only)
In order for the applets to be loaded correctly, you must add the IP address of the controller
to the list of site exceptions in the java control panel. This can be found in the computer’s
control panel. Once the java control panel is open, select the Security tab as below.
