Primary Conduit Locations for Top or Bottom Entry
[ ] = Dimensions in mm.
➀ Primary conduit locations for top or bottom entry.
➁ Recommended minimum clearance to rear of
VacClad-W: 36 inches [914.4].
➂ Floor steel, if used, must not exceed 3.25 inches
[82.55] under VacClad-W.
➃ Anchor locations: indoor – 0.5-inch [13] bolts or
weld, outdoor – 0.5-inch [13] bolts.
➄ Station ground connection provision.
➅ Secondary conduit space: All – maximum of
1-inch [25.4] projection.
➆ Minimum clearance to LH side of VacClad-W:
32 inches [812.8].
➇ Finished foundation surface (including floor
steel) must be flat and level and in true plane.
➈ Minimum clearance to front of VacClad-W:
70 inches [1778].
➉ Changes to 8.25 [209.55] if optional hinged rear
doors are required.
Note that the figure above shows that the
arrangement of components differs between
upper and lower panels. The figure may also be
used to select custom arrangements of hinged
panel components.
Use of multipurpose solid-state relays such as the
Cutler-Hammer Digitrip 3000 (same size as device
7) will significantly reduce consumption of panel
space.
