5.8.1 Enclosure layout
Observe the clearances in Figure 5-3 taking into account any appropriate notes for other devices / auxiliary equipment when planning the installation.
A Unidrive SPMA is shown, but the illustration also applies to a docked Unidrive SPMD and SPMC.
Figure 5-27 Enclosure layout
Ensure minimum clearances
are maintained for the drive
and external EMC filter. Forced
or convection air-flow must not
be restricted by any object or
cabling
For EMC compliance:
1) When using an external EMC
filter, one filter is required for
each drive
2) Power cabling must be at
least 100mm (4in) from the
drive in all directions
