Features and Modifications
Table 3.A Motor Control Center Vertical Section Features and Modifications
1 All 1336 D and E-frame drive units and common DC bus F-frame drive units and PowerFlex frames 4 - 9 have 20" deep sections as standard. Common AC bus F-frame drive units and all
G-frame and H-frame drive units have 25"bump-back sections as standard.
2 If you are using a Bulletin 2364 front-end common-DC-bus supply unit in your lineup, verify that the front-end depth is compatible with the Bulletin 2362 sections that you are selecting.
3 If ANY one section is at least 20" deep, then ALL sections in that lineup must be at least 20" deep.
4 You must specify a power bus and a ground bus for each section.
5 3000A-rated horizontal power bus requires a 1/4" x 2" horizontal ground bus (PE) selection. Zero potential bus (TE) remains at 1/4" x 1" regardless of horizontal ground bus (PE) size selection.
Splice kits with 1/4" x 2" PE contain three 1/4" x 1" bus splices (Qty 2 for PE + Qty 1 for TE); splice kits with 1/4" x 1" PE contain two.
6 One kit required per shipping split on flush-front lineups. (Control bus splice kits are only required if lineup has control bus.)
7 Common AC bus F-frame drive units and all G-frame and H-frame drive units require base channels.
8 If you are using a Bulletin 2364 front-end unit in your lineup, lookup the base channel requirements of the front-end being utilized.
9 If ANY one section has base channels, then ALL sections in that lineup must have this optional base channel factory-installed. Base channels add 1.5" to the overall section height.
10 PowerFlex® frame 10 requires a 25” deep flush back section.
