ATTENTION
Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). There are
two grounding points for the unit. One point is the 3-pin terminal block connector for power. Underneath the
bottom mounting appendage is another grounding point.
For DIN-rail mountable units: Ground the DIN rail itself. The modem's grounding point under the mounting
appendage will be in direct contact with the rail. Be sure to ground the DIN rail before connecting the modem
to the DIN rail.
For wall or panel-mounted units: Run a ground wire from the right-most pin of the terminal block connector. Be
sure to connect the ground wire before connecting devices to the modem.
