Use the following steps for panel mounting in an NEMA enclosure.
NOTE: There should be at least 6 inches (150 mm) of clearance at the top
and bottom of base for adequate airflow. The base depth is 7.99 inches
(203 mm).
1. Open NEMA enclosure door.
2. Drill four holes in sub-panel of NEMA enclosure with a #21 drill bit.
Refer to Table 3-2 for screw-hole dimensions for each base.
Ensure that chips from drilling do not contaminate other equipment.
3. Tap the drilled holes with a #10-32 tap.
4. Position the base inside the NEMA enclosure.
NOTE: Be sure that the bracket holes and the tapped holes in the sub-panel
are aligned.
