Storage and Operation
CENTERLINE MCCs conform to NEMA standard ICS 1-2000 for service and
storage conditions. All MCCs should operate in an ambient temperature above
0
o
C (32
o
F) but not exceeding 40
o
C (104
o
F) at 95% non-condensing humidity.
If the equipment is stored, the ambient temperature should remain above
-30
o
C (-22
o
F) but not exceed 65
o
C (149
o
F). In addition, MCCs have an
altitude class of 2 km (1 km for MCCs that contain variable frequency drives).
The altitude class of 2 km designates equipment for installation where the
altitude does not exceed 2000 m (6600 ft). For installation above
2000 m (6600 ft), contact Rockwell Automation LV MCC Technical Support at
1.440.646.5800 and follow the prompts to Allen-Bradley>Low Voltage Motor
Control Centers>Post Shipment Support.
