4.2 Board mounting considerations
The TMCM-3214 / TMCM-3215 offer 12 metal plated mounting holes. One hole (lower right) is connected to on-
board system ground (connected to power supply input ground) via 1M (500VDC) || 1nF (1kV). The same
combination or resistor and capacitor is used for connecting the RJ45 shield ground (connector enclosure) to
power supply input ground (see figure 4.2).

Figure 4.2 TMCM-3214 / TMCM-3215 mounting hole connections
All other mounting holes are electrically isolated. Please note that not all holes have to be used for mounting
the pcb. At least the mounting holes in all four corners and two in the middle (6 altogether) should be used to
ensure adequate support of the pcb when inserting / removing connectors in order to avoid significant bending
of the pcb.
In any case: please remove / attach mating connectors carefully – supporting the pcb if necessary!
