AS YOU LIFT AND TILT MODULE
TO REMOVE IT FROM RAIL
When attaching the module to the
T-type DIN rail, angle the top of the
unit towards the rail and locate the
top groove of the adapter over the
upper lip of the rail. Firmly push the
unit towards the rail until it snaps into
place. To remove, first separate the
input terminal block(s) from the
bottom side of the module to create a
clearance to the DIN mounting area.
Next, while holding the module in
place from above, insert a
screwdriver into the lower arm of the
DIN rail connector and use it as a
lever to force the connector down
until the unit disengages from the rail
(do not twist the screwdriver to avoid
damaging plastic).
The Ethernet port of this unit is wired MDI-X by default, but includes
automatic crossover (the Ethernet port of your PC is typically wired MDI).
Thus, you can use either a straight-through or crossover cable to connect
this device directly to a PC, Ethernet switch, or another unit.
CONNECTIONS

Mounting & Removal
Network
For 100Base-TX systems, at a
minimum, use data grade
Unshielded Twisted-Pair
(UTP) wiring that has a 100Ω
characteristic impedance and
meets the EIA/TIA Category 5
wire specifications.
It is recommended that you
use a CAT-5 cable to connect
this device to your PC.
For 10Base-T systems, you
may use Category 3, Category
4, or Category 5/5E UTP/STP
cable.
In either case, you are limited
to 100 meters between any
two devices.
