Storage and Operation
CENTERLINE MCCs conform to NEMA standard ICS 1-2000 for service
and storage conditions. MCC ambient operating temperature range is
0…40 °C (32…104 °F) at 95% noncondensing humidity. Ambient storage
temperature range is -30…65 °C (-22…149 °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
