2 DESCRIPTION
The 9475-ETG is an Intrinsically Safe (IS) Gigabit Ethernet Dual Port Media converter
suitable for Zone 1 / Zone 21 mounting, (Zone 0 / Zone 20 with a suitable Ex ia Power
Supply).
There are 2x RJ45 (LAN) ports that support 10/100/1000 IS Ethernet connections –
these can allow ‘daisy-chaining’ of units together.
There are 2x Fiber-Optic Type SC (1310nm) connections presented.
The use of 1310nm optics allows a longer fibre-optic link length, typically 10Km at
(Gigabit) 1000Mbps using Single Mode fibre or 500m when using multi-mode fibre.
Power (12V DC) is supplied to the module locally.
The compact and cost effective design makes it the ideal choice for many applications:
Petrochem
Process Monitoring & Control...
Mining
Underground Communication Links, PLC and Machine Monitoring…
Electrical connections are via cage-clamp and/or screw type plug/socket terminals
along with RJ45 type connectors for the Ethernet LAN ports.
The Fibre ports are duplex SC Type.

7 WASTE REMOVAL INFORMATION
The electronic equipment within must not be treated as general waste. By
ensuring that this product is disposed of correctly you will be helping to
prevent potentially negative consequences for the environment and human
health, which could otherwise be caused by incorrect waste handling of this
product. For more detailed information about the take-back and recycling
contact Controlled Systems Ltd

8 INSTALLATION
The module requires mounting within an enclosure providing a degree of protection of
at least IP6x, in accordance with EN60529 and in a manner that does not impair the
existing creepage and clearance distances. The enclosure must also comply with the
requirements of Clauses 7 and 8 of EN50014 and be sealed to prevent the ingress of
dust.
The 12V supply to the module connects via screw terminals 1 + 2 as shown above.
As the 9475 Gigabit Media Converter supports Auto MDI/MDI-X, a straight connected
RJ45 Cat5e cable is used to connect to any device required, it is also possible to daisy-
chain the units using the two LAN ports.
It is recommended that Cat5e cables for Hazardous Area Zone 1 use are ‘Blue’ in
colour and are of good quality (see accessories section), the Safe Area cables being a
colour other than blue to aid identification.
The operating parameters must not exceed those as detailed on the certificate.
This apparatus must only be installed or replaced by a competent person who must
ensure that existing IS segregation is maintained.

12 CONNECTING THE 9475-ET(G)TO A PC/NETWORK
Ensure that the 9475 unit is powered by a suitable IS supply, such as the MTL
9492-PS-PLUS. PoEx can be used to power the unit via the LAN port if required.
The 9475 unit should then be connected to an IS Ethernet Network/PC using a
suitable CAT5/6 cable. Either LAN Port 1 or 2 can be used. The other LAN port can
be used for daisy chaining units together.
Run the 9461-ET Finder.exe program which can be found on the MTL website, this
will automatically search for and locate any 9475 units connected to the network.
Click on the device that you are looking to configure, then click the “configure IP
settings” button and this will bring up the following screen
Manually type in the settings that you require and then enter the password “CSL”.
Click the apply button to send the settings to the 9475.
Reboot the device by either powering down or by clicking the “reboot” button in
the above screen.
Once the 9475 is up and running, navigate to the IP Address that has been
programmed into the unit using a web brower.
