Surface-mounting the Drive
1. Use the two surface-mounting brackets. These
are manufactured from metal. Ensure the
brackets make direct electrical contact with the
back-plate; for example, tap M6 (

/
4
in)
threaded holes in the back-plate in the positions
shown in Figure 2–10 to accept the mounting
screws. (For model size 1, you may use the
central or, preferably, the two outer screw
holes in the mounting bracket.)
2. Insert the surface mounting brackets into the
slots in the top and bottom of the Drive
heatsink, as shown in Figure 2–9.

bracket in a heatsink
3. Retain the mounting brackets to the back-plate
using electrically conducting screws.
Note
When surface mounting a model size 3,
allow a clearance of 150mm (6in) above the
Drive; this is required for dismounting. A
minimum clearance of 100mm (4in) is
required for ventilation.
