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 mounted 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.
