Power cabling options

The UPS input mains, output supply and battery power
cables are connected to busbars fitted in the distribution
frame and fully accessible from the front of the cabinet.
The busbar connections are identified on a label attached
to the inside of the distribution frame door, as shown in
Figure 4.9 (TOP). Notice that there are three pairs of
battery connections on both the left and right sides of the
distribution frame (X501 - X506).
The cable connection busbars shown are bolted to further
busbars that run across the entire lower back of the UPS
cabinet to make the power connections available in each
of the UPS module frames.
The battery busbars similarly pass across the back of the
cabinet to the module frames but in this case the busbar
connections are made using flexible busbars (flexi-bars)
to allow the batteries to be connected in various
configurations (see paragraph 4.3.3).
The distribution frame busbar construction is shown in the
lower illustration of Figure 4.9.
The AC and DC cable groups can be connected using
either top or bottom cable entry and can be split so that
one group enters the top of the distribution frame and the
other enters the bottom. The lower illustration in
Figure 4.9 shows top cable entry for all AC and DC cables
– examples of other cable entry configuration are
provided in Figure 4.10 to Figure 4.13.
Note that the cable colours shown in the illustrations are:
• brown – input/output AC (L1)
• black– input/output AC (L2)
• grey – input/output AC (L3)
• light blue – neutral (N)
• green – earth (PE)
• red – battery positive (B+)
• dark blue – battery negative (B–)
CAUTION: These colours do not conform to
any particular international standard and are
used for illustrative clarity only.
The cover plates fitted to the top and bottom of the
distribution frame can be removed to fit suitable cable
glands as shown in the diagrams.
