• Minimum H1: 1.7 m (67 in.)
• Minimum H: 1 m (39 in.)
Additional Notes
•
The walls of the plenum exit area must be capable of withstanding the
pressure generated.
•
Any painted surfaces which directly face the arc products may ignite.
Flame suppression is recommended.
•
The exit point can also be outside the building. Ensure the exit area
cannot be blocked by ice, snow, or vermin nests.
•
Access barriers are recommended as a means of restricting access by
personnel while the equipment is energized. Chain link fencing is a
suitable barrier material.
•
Equipment that consists of more than 4 vertical sections that are bolted
together may require additional plenum exits. Rockwell Automation will
provide guidance on requirements for additional plenum exits when
required.
