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
and
).
2. Plenum duct to outside of control room (see
and
).
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
through
