supply only of the type described in the operating instructions or as
marked on the unit.
11. Grounding or Polarization — Precautions should be taken so
that the grounding or polarization means of the unit is not defeated.
12. Power Cord Protection — Power supply cords should be routed
so that they are not likely to be walked on or pinched by items
placed upon or against them, paying particular attention to cords at
plugs, convenience receptacles, and the point where they exit from
the controller.
6. Carts and Stands — The unit should be
used only with a cart or stand that is
recommended by the manufacturer. A unit
