Spreaders must be used to provide the
vertical lift on single controllers to prevent
eyebolt failure. Always keep the controller
upright while lifting.
Some enclosure sections may contain
heavy or special equipment that cause the
center of gravity to be off center.
A 4 ton to 7 ton rated fork lift is required
depending on weight as listed in Table 1
Figure 7 -
Lifting and assembly
LD12154a
Adjust rigging lengths to maintain the enclosure in a
upright position. The angle between the lifting cables
and vertical must not exceed 45°. Ropes or cables must
not pass through the holes in lifting angles or eyebolts.
Use slings with safety hooks or shackles of adequate
load rating.
After the enclosure sections are in place, bolt together
with 1/2 in. hardware supplied, then install and wire
the fan assemblies. Connect the DC bus cables to the
modules and plug in the control connector. Assemble
the ground bus splice(s).
