H. Proceed with stacking of remaining modules, checking
that stack is plumb in both axes as stacking progresses
before torquing hardware. Be certain to check the
layout/wiring diagram for correct horizontal orientation to
provide proper polarity interconnection as stacking
progresses. See Figure 17B.
8.2 Horizontal-Multiple Stacks
It is recommended that all of the first modules with bottom
supports attached (see Section 8.1.1) be placed in position
first. A chalk line floor mark should be used to assure all
stacks will be in a straight line. This applies for stacks end-
to-end or end-to-end and back-to-back. Also refer to Section
8.1.3, Items A through H (Item E for base module leveling).
Module ends should be butted together so that module side
channel ends meet (see Figure 18).
Refer to layout/wiring diagram for seismic shim requirements.
At this time stack tie plates should be installed (see Section
8.2.1). It will be necessary to temporarily remove the hard-
ware fastening the base modules to the I-beams.
See Figure 20A. Install tie plates and hardware. Torque to 47
Newton-meters (35 Ft-Lbs).
For stacks back-to-back, the two base modules are posi-
tioned to provide a minimum 4.5” spacing between the bot-
toms of the modules (not I-beam edges). See Figure 19A.
When all base modules are set in place, continue with stack-
ing of subsequent modules. Procedures for assembly of
multiple horizontal stacks are the same as outlined in section
9.1. Also consult layout/wiring diagram. Each stack should be
built up in sequence to the same level until the top modules
in all stacks are the last to be installed. The use of a line cord
attached to upper module corners of opposite end modules
as stacking progresses aids in alignment. See Figure 19B.
