PowerBrick™ Installation Chapter 3
Dimensions Refer to Figure 2 , Figure 3 , and Figure 4 for PowerBrick dimensions and
mounting.
Torque Requirements All electrical connections must be torqued to the specifications shown in Table 4 .
Table 4 - Torque Requirements
PowerBrick Mounting PowerBricks are to be mounted in a vertical orientation in order to provide
adequate component cooling. Mount the PowerBricks in a suitable location using
the mounting holes provided in the assembly (refer to
Figure 2 ). Use
M8 (5/16 in.) or similar hardware for the mounting hole dimensions of
10.7 x 15.9 mm (0.421 x 0.625 in.).
PowerBricks are provided with two methods for mounting (as shown in
Figure 2 ). The PowerBricks can be mounted to a vertical surface using the four
mounting locations on the rear face, or they can be mounted to a horizontal
surface using the four mounting locations on the base.
Note: Using either mounting option requires space above and below each phase
assembly (refer to
Figure 3 and Figure 4 ).
ATTENTION: Ensure that all electrical connections are torqued to the correct
specification. Failure to do so may result in damage to the equipment and/or
injury to personnel.
