The 431B Cabinet has four mounting holes to anchor the unit after is has been set in place. See Figure 10-3. Use 1/2 in (12 mm) bolts to anchor the 431B.

Verify the Left Side Access Plate of the 431B and the corresponding Right side ac- cess plate of the 4300 UPS are removed before anchoring the unit.

NOTE: Ensure the 431B can be joined to the UPS before final anchoring of the 431A. Use four 3/8 in. -16 x 2 in long bolts to bolt the ancillary cabinet frames together.
