5.7 Mounting methods
Unidrive SPMA, SPMD and SPMC can be either surface or through-
panel mounted using the appropriate brackets.
Surface mounting is where the drive is simply secured to the enclosure
wall/backplate.
Through-panel mounting is where the drive is secured with the heatsink
protruding through the enclosure panel to the external environment. This
has the effect of reducing the temperature within the enclosure.
The following drawings show the dimensions of the drive and mounting
holes for each method to allow a back plate to be prepared.
