40 Guidelines for planning the mechanical installation
Layout example, door open
WARNING! Attach the cabinet to the floor or prop it up from the back. The module
has its center of gravity at the back and the cabinet easily topples over.
Note 1 : The power cable shields can also be grounded to the drive module grounding
terminals.
Note 2: See also section Required free space , page 45 .

Arranging the grounding inside the cabinet
Arrange the grounding of the drive module by leaving the contact surfaces of the fastening
points unpainted (bare metal-to-metal contact). The module frame will be grounded to the
1 Cabinet back plate. The maximum allowed
depth of the back plate is 60 mm (2.36 in.)
in order not to cover the air flow grate at
the top off the heatsink.

control unit (P905), the upper door air inlet is
critical for proper cooling of the control board.
