INSTALLATION STEPS
Step 1 −Drill mounting holes in panel for specific disconnect device being installed. See installation instruc-
tion index above for appropriate panel drilling instructions. Additional holes may be required when using
fused switches. See disconnect manufacturers instructions.
Step 2 −Install operating handle on enclosure flange in holes provided. Follow disconnect manufacturers
instructions.
Step 3 −Install disconnect device on panel. Follow disconnect manufacturers instructions for installation
and adjustment.
Step 4 −Install door hardware on enclosure door. See table 3 on page 3 for selection of appropriate 2−point
or 3−point door hardware. Follow disconnect manufactures instructions and Hoffman additional information
to install door hardware. See disconnect manufactures instructions to adjust door hardware to properly in-
terlock to disconnect operating handle.

Note 1 −Hoffman enclosures include a latch bar and have a door catch and stud−type standoffs provided on the door. Therefore;
Allen−Bradley door hardware items 19, 20, 21, 22, 24, 25, 26, and the Allen−Bradley door catch (shown in figure 4 of the Allen−Bradley
instructions) can be omitted. The Allen−Bradley pivot plate (item 23) is to be installed on the stud−type standoffs with the sleeve and
locknut provided by Hoffman. Fasten the Allen−Bradley defeater actuator (item 30) to the latch bar. The latch bar has six (6) mounting
holes. Use the top holes for eight (8) inch deep enclosures, middle holes for ten (10) inch deep enclosures, and the bottom holes for
twelve (12), and sixteen (16) inch deep enclosures.
Note 2 −Hoffman enclosures include a latch bar and have a door catch and stud type standoffs provided on the doors. Therefore the
Cutler−Hammer door catch and some door hardware items will not be needed (CH items no. one (1) through six (6)). Install the CH
defeater bracket (item 28) onto latch rod (furnished with enclosure). The latch rod has six (6) mounting holes. Use the top pair of holes for
eight (8) inch deep enclosures, the middle holes for ten (10) inch deep enclosures, and the bottom holes for twelve (12) inch and sixteen
(16) inch deep enclosures. Adjust door hardware as required.
Note 3 −Hoffman enclosures include a latch bar and have a door catch and stud−type standoffs provided on the door. Therefore, G.E.
door hardware items 17, 18, 20, 21, and 22 can be omitted. Use optional mounting of upper latch (figure 1a on G.E. instructions) where
upper latch roller contacts top of enclosure flange. The G.E. roller assembly (item 19) should be installed on the stud−type standoffs with
the locknut provided by Hoffman. Install the G.E. interlock bracket (item 23) ont the latch bar. The latch bar has six (6) mounting holes.
Use the top holes for for eight (8) inch deep enclosures, middle holes for ten (10) inch deep enclosures, and the bottom holes for twelve
(12), and sixteen (16) inch deep enclosures.
Note 4 −Hoffman enclosures include a latch bar and have a door catch and stud−type standoffs provided on the door. Therefore, Square
D door hardware items 10, 13, 22, 23, 24, 25, and 26 can be omitted. The Square D latch arm (item 16) is to be installed on the stud−type
standoffs with the sleeve and locknut provided by Hoffman. Note: Assemble the upper Square D latching arm to the latch bar as shown in
of Square D instructions. Also see Figure 6 (above) which shows correct assembly of door hardware. Fasten the Square D latch bar
bracket (item 8) to the latch bar. The latch bar has six (6) mounting holes. Use the top holes for eight (6) inch deep enclosures, middle
holes for ten (10) inch deep enclosures, and the bottom holes for twelve (12) and sixteen (16) inch deep enclosures.
Note 5 −Hoffman enclosures include a latch bar and have a door catch and stud−type standoffs provided on the door. Install the I−T−E
roller assembly on the stud−type standoffs with the locknut provided by Hoffman. Fasten the I−T−E interlock defeater lever to the latch bar.
The latch bar has six (6) mounting holes. Use the top holes for eight (8) inch deep enclosures, middle holes for ten (10) inch deep
enclosures, and the bottom holes for twelve (12) and sixteen (16) inch deep enclosures.
