Installation of Exhaust Air Hood

Even though this is a liquid-cooled drive, some sections still require
air circulation.

On the top of the cabinets with cooling fans, sheet metal exhaust
hoods are to be installed. The components to make up the exhaust
hood have been packaged and shipped with the drive and are to be
found on a separate skid marked with the same identifying tags on
the skid.

The first step is to remove the protective plate covering the fan
opening on the drive. It is a flat cover plate bolted to the top plate.
Remove the bolts and plate and keep the hardware for reuse.

Secondly, locate the fan hoods on the separate skid and lift these
over the respective holes located on the top of the drive cabinet.

Locate the exhaust hood on top of the cabinet per Figure 2.35 and
reuse the existing hardware set aside earlier. (Care must be taken
that the notches on the bottom flange are oriented toward the sides of
the drive). Affix assembly to the drive top plate. Tighten all
hardware.
