Weidmuller WI-MOD-E-A & -E-G: Wireless Ethernet & Device Server v1.9 - Manual

FCC Statutory Requirements
Unlicensed operation limits the radio power. High gain aerials may only be
used to compensate for cable losses.
9-30V
DC Supply
NOTES
ALL connections must be SELV (Safety Extra Low Voltage <50V AC & <120V DC)
Ethernet Port wiring is that of a hub or switch.
‘-' Supply terminal and 'M4 GND screw on rear of module' must be connected to EARTH /
GROUND as close as practical to the unit.
Module Power Supply -Ve terminal is not Isolated from Earth/GND
DIO channel can be wired as either input or output.
Care must be taken with antenna selection and proximity to the radio.
The non-metallic cover of the Wireless Ethernet Modem is considered to constitute an
electrostatic discharge hazard. Clean only with a damp cloth
The Wireless Ethernet Modem enclosure contains aluminum and is considered to constitute a
potential risk of ignition by impact or friction and must be taken into account during installation.
If the Wireless Ethernet Modem is installed as Category 3 equipment, then it shall be installed
in an Enclosure which maintains an ingress protection rating of IP54 and meets the enclosure
requirements of EN 50014 or EN60079-0.
If installed in a hazardous environment coaxial cable shall be installed in a metallic conduit as
per NEC requirements
