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 81 , Figure 82 and
Figure 83 ).
2. Plenum duct to outside of control room (see Figure 81 and Figure 82 ).
Plan the location where the plenum will exhaust. Ensure that:
• 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 81 through Figure 83 .
