Overview
LevelOne IEC-4000 is an industrial Fast Ethernet media
converter with a rugged aluminium case which providing superb
heat dissipation. This converter is designed to be mounted on
an industrial standard DIN-rail, plus the clearly visible status
LEDs provide simple monitoring of port link activity. It also
features Link Fault Pass Through in order to alert remote
location when link status changes.
High Reliability
All components are built to withstand harsh environment
applications without compromise where humidity, temperature
variation and even shock vibration are concerns, including
Electric & Utility, Critical Infrastructure, Transportation and
Surveillance Security. This device operates under -40 to 75
Celsius (-40 to 167 Fahrenheit) temperature.
Ultra-Compact
The ultra-compact converter has the smallest form-factor of any
such device in the world, but still offers industrial levels of
toughness. Housed in a rugged IP31 aluminium case with inbuilt surge and ESD protection, the device measures just
59mm by 49mm, with a height of 36mm.

Power Input
Note:
This unit provides 3 pin terminal-block. And it can be operated
using either VAC or VDC power source. The VDC power range
is from 12VDC to 60VDC, and the VAC power range is from
18VAC to 36VAC. Always Make sure your input voltage is
within this supported voltage range.
WARNING – any exceeded input voltage will not make this unit
function and may damage this unit.
To make power connection – Follow the printed polarity for V+,
V- and Ground. Connect positive wire to V+, connect negative
wire to V-, and also connect neutral wire to ground.

DIP Switch
Note:
This unit is equipped with dip switches, located on the front
panel marked as SW1. Adjusting the dip switches will change
the default function of this unit. This unit has set to
manufacturer default as: switch mode and LFP function off.
The table shown as you may change the dip switch setting to
your desired environment.

DIN Rail Mount
Assembly: Place the switch on the DIN rail from above using
the slot. Push the front of the switch toward the mounting
surface until it audibly snaps into place
Start-up: Connect the supply voltage to start up the switch
via the terminal block (or DC JACK)
Dismantling: Pull out the lower edge and then remove the
switch from the DIN rail
