Installation Procedures
Location Planning
When planning the location for your CENTERLINE Motor Control Center,
consider the following:
•
Conduits
•
Busways
•
Overall height of installation area
•
Alignment with other equipment
•
Future needs
•
Ambient temperature
The area must be level and the environment must be compatible with the
NEMA enclosure rating of the equipment.
Height Considerations
If the motor control center is equipped with optional external mounting
channels or is mounted on a pad, the height from the floor to the center of the
top handles must be checked for compliance with 2005 NEC 404.8(A) and UL
Standard 845. If the distances from the floor to the center of the highest
handle is greater then 6’7” (2000 mm) a unit operating handle extender should
be added (catalog number 2100H-NE1). See Figure 2.1.
