Expansion shelves are supplied with a short cable to link the J1 connectors between 

the base unit and the expansion shelf.

 

Above J1 is a 4-way Spring Clamp Terminal connector.  This connector, designated 

J2, provides terminations for the auxiliary digital alarm input and the optional external 

temperature probe.  The pin-out for this connector is described in section 11.

 

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  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.
