Plenum Exhaust Considerations
The following options for locating the plenum exhaust are presented:
1. Plenum ducted to an area of the control room where arc gases are
permitted to escape, with plenum extensions (see Figure 60 , Figure 61 ,
and Figure 62 ).
2. Plenum duct to outside of control room (see Figure 60 and Figure 61 ).
Plan the location where the plenum will exhaust.
• There is no access to personnel while equipment is energized.
• Area is free of flammable material or vapors.
Ensure that adequate space is provided around the plenum exhaust, as
outlined in
Figure 60 through Figure 62 .
