INSTALLATION & OPERATING MANUAL
Manual No. x75-10b
x75-man-Rev10b-0514.indd
9.4 In the center of the unit are three bus bar terminals.
9.4.1 To the left side is the VB or BAT terminal. This is connected to the ‘hot’
or ‘feed’ side of the battery.
9.4.2 In the middle is the –V or –VO terminal. This is the ‘negative’ output of
the rectier bus.
9.4.3 To the right side is the +V or +VO terminal. This is the ‘positive’ output
of the rectier bus.
9.4.4
Battery connection for -48VDC systems is as follows:
+Ve battery terminal connects to the +V terminal.
–Ve battery terminal connects to the VB terminal.
Note that in -48VDC systems the +V terminal is internally connected to chassis
ground.
9.4.5 Battery connection for +24VDC and +12VDC systems is as follows:
+Ve battery terminal connects to the VB terminal.
-Ve battery terminal connects to the –V terminal.
Note that in +24VDC and +12VDC systems the -V terminal is internally connected
to chassis ground.
9.4.6
When the system is required to provide a bulk feed output without using
the internal distribution the +V and –V terminals are used to provide this
feed to the load.
9.4.7 When an expansion shelf is used to increase the overall capacity of the
system the +V and –V terminals of the expansion unit should be bussed
together with the +V and –V terminals of the system unit respectively using
the supplied link bars.
9.5 Immediately to the right of the bus bar terminals is a bank of 15 Spring Clamp
Terminals designated J4. These terminals provide connections for the battery
temperature compensation probe and the relay alarm outputs. They are described
in detail in section 11.
9.6
Next to J4 is a 25-way Sub-miniature D-Type connector, designated J1, which is used
to connect various signal and control lines between a base unit and an expansion
shelf.
