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 71
, Figure 72 and Figure 73).
2. Plenum duct to outside of control room (see Figure 71
and Figure 72).
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 71
through Figure 73.
