EVICES
The EPMs-PS1 circuitry is protected from spike and surge damage by on-board transient voltage
suppression (TVS) devices on the power out signals. In order for the TVS devices to function
properly, they must be connected to earth ground. This connection is made at the board’s lower
right mounting hole, as shown in Figure 2. All other mounting holes are floating. Use metal
standoffs or a grounding strap to connect the lower right mounting hole to the enclosure chassis,
which should be connected to earth ground.

Only the lower left mounting hole
connects to the TVS devices. This
hole must be connected to earth for
TVS protection to function.
