NOTE:

1.All dimensions are in millimeters (in).

2.Eight-inch minimum clearance above unit required for air exhaust.

3.Keep cabinet within 15 deg. of vertical while handling.

4.Top and bottom cable entry available through removable access plates. Remove access plate, punch to suit conduit size and replace.

5.Color - black.

6.Unit bottom is structurally adequate for forklift handling.

7.M10 threaded mounting holes used for seismic anchoring or floor stand.

NOTE: If floor stand is used, the weight of the unit must be supported under all casters.

8.Each mounting location is supported by two 10 ga. (.135") galvanized steel. The threaded insert is approximately 3/4" deep. Mounting holes are underneath unit base; mounting bolts must be threaded into unit.

9.Side panels must be removed from adjacent units that are bolted together.

10.Leveling feet are not designed to carry the full weight of the cabinet. Finger-tighten leveler against the floor, then tighten with a wrench less than 2 turns for friction fit against floor.
