Front vertical splice plate (elbow) (see
item 10).
The splice plate fits in a gap between the back of the low-volt-
age compartment and the front of the main bus compartment.
Attach the horizontal part using 4 sets of M8-1.25 x 25 lg
SHCS, M8 wide washer, M8 split lock washer, M8 nut.
Attach the vertical part using 12 sets of M8-1.25 x 25 lg SHCS,
M8 wide washer, M8 split lock washer, M8 nut.
Top horizontal splice plate (see
, item 11).
Attach using 4 sets of M10-1.5 x 30 lg SHCS, M10 wide flat
washer, M10 split lock washer, and M10 nut.
Bus tie vertical sections
If the system includes bus tie vertical sections, there will be a cutout
in each vertical section’s cable compartment side walls to accommo-
date bus connections.
These cutouts will require two attachments above the cutout and
two attachments below. Each bus tie vertical section left-hand side
wall will have holes for fasteners. The right-hand side wall will have
weld nuts for mating with the attachment bolts.
Attach at the cutout top and bottom using 4 sets of M8-1.25 x
25lg SHCS, M8 wide flat washer, and M8 split lock washer.

Connect the cable compartment horizontal ground buses
using a copper splice plate (see
Figure 84. Ground bus copper splice plate.
Figure 85. Ground bus splice plate installed.
Install and connect SSIS bus in main bus compartments (see
section
).
Bolt next vertical section to cable vault rails.
5.7.2.6 Obtain the next vertical section in the lineup, and
repeat from section 5.5.2.4
5.8 Low voltage control connections
Refer to the project schematic and wiring diagrams for information
on control connections. Refer to Section 5.13 for information on
cable routing, glands and caulking.
5.8.1 Auxiliary circuits available to the user
Refer to the project schematic and wiring diagrams for information
on auxiliary signals available to the customer.
5.9 Installing SSIS bus and bus joints
Solid Shielded Insulation System components provide modular
shielded busbar conductors protected by solid insulation. The
system includes shielded bus sections and coupling bus joints so
that the completed installation is mechanically robust, impervious
to environmental conditions, and with the shielding features, has no
local electric field around the conductors.
