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.
