4.2 Board mounting considerations

The TMCM-3314 / TMCM-3315 offer 12 metal plated mounting holes. One hole (close to power supply connector)

is connected to on-board system ground (connected to power supply input ground) via 1M (500VDC) || 1nF (1kV).

The same combination of 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-3314 / TMCM-3315 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!
