Wiring
The Outdoor Ethernet Switch Assembly contains a power supply module and Ethernet switch module mounted
on an assembly bracket. The modules will need to be removed from the mounting bracket to complete the
requiredwiring.UseaPhillipsheadscrewdrivertoremovetheDINrailstopfromthebracketshowninFigure
1. Use a small slot head screwdriver to pry the release tab of the power supply module. Now slide the modules
off of the mounting bracket.
The Switch Assembly is provided with the DC power supply pre-wired to the Switch module. Therefore, the
user will only need to provide the AC input and ground wiring to the assembly. The AC input power should be
wired to the power supply connections labelled ‘L’, ‘N’, and Ground (symbol) in the Ethernet Switch Assembly
as shown in Figure 2. The Ethernet Switch module provides a ground connection which should be connected
to earth ground, see Figure 3. A grounding stud is provided to tie all ground connections together. Once all
connectionsaremade,mountthemodulesbackontheassemblybracketandsecurethemoduleswiththeDIN
rail stop.

The Switch Assembly provides 5 or 8 Ethernet ports, depending on the model. One of these Ethernet ports are
required to connect the Switch Assembly to a network or computer, leaving the remaining ports available for
othernetworkeddevices(1218CElectronicTankGauges,1218CWirelessClient,1218CExternalInput/Output
Expansion Module, 1218C Cellular Gateway, Modbus devices, etc.). Once all connections are made and devices
areallpoweredon,verifytheconnectionindicatorsforeachoccupiedEthernetportareilluminatedorashingas
