The N-Series Drives are designed to be used in a wide variety of operating conditions. As shown in Figure 3-6 they
have a robust mechanical design that allows rigid mechanical attachment at the two primary interface points; the
interface between the N-Series Drive and the user PCB, and the interface between the N-Series Drive and the heat
sink or cold plate also called a supporting plate. The following sections describe how mechanical attachment at both
these interfaces occurs.
3.7.1 Attachment to the User PCB
Attachment at the PCB is accomplished by soldering the PCB to the N-Series Drive’s four mechanical alignment posts.
While these posts do not serve an electrical function, they provide a rigid attachment of the PCB to the N-Series ION,
and thereby reduce strain that may occur in the solder connections between the user PCB and the Power and Signal
Connectors of the N-Series ION. Use of the four PCB alignment posts are recommended for all applications.
