5.7.3 Mounting brackets
Table 5-1 Mounting brackets
5.7.4 Installation of the Unidrive SPM mounting
brackets
Common
The Unidrive SPM range use the same mounting brackets for surface
and through-panel mounting.
The mounting bracket has a long section and a short section.
Figure 5-22 Unidrive SPM mounting bracket
The mounting bracket must be installed in the correct orientation with the
long section inserted into or attached to the drive and the short section is
attached to the back plate. Figure 5-23 shows the orientation of the
mounting bracket when the drive is surface and through-panel mounted.
Figure 5-23 Orientation of the Unidrive SPM mounting bracket
When through-panel mounted, the mounting brackets on the left hand
side of the Unidrive SPMA and SPMD can be secured using the screws
already located there. This only applies to the bottom of the Unidrive
SPMC/U rectifier.
On the right hand side, the mounting brackets are just inserted into the
slots in the chassis of the drive; no mounting screws are present here.
Drive specific brackets
Unidrive SPMA
Unidrive SPMA also requires two top mounting brackets when the drive
is surface mounted. The two brackets should be installed to the top of
the drive as shown in Figure 5-24.
