2 Installation2.1 Setting the gateway's field bus addressGateway XN-312-GW-CAN 06/16 MN050003-EN www.eaton.eu 252 InstallationGateways must only be installed and wired up by qualified electricians orother persons familiar with electrical engineering.The gateway is installed in the following order:• Adjust the field bus address at the device.• Set the Baud rate on the device.• If the gateway is the first or last module on the field bus, use the DIPswitches to activate the bus termination resistor in the device.• Join the gateway and all I/O slice modules to form a system block.• Mount the system block on the DIN-rail.• Connect the power supply.• Connect the field bus.2.1 Setting the gateway's field bus addressBefore mounting the device, set the field bus address using the DIPswitches (DIP = dual in-line package) at the front of the gateway.Follow the example below in order to configure an address on the gateway -18 (decimal) is used as an example in this case:18 dec = 16 + 2 = 1 · 2 4 + 1· 21The address is to be set at the dip switches.▶ Set the CANopen address using DIP switches 1 - 5; refer to ￫ Section“1.5.3 Valid device field bus addresses”, page 23. DIP switches 1 and 4must be switched to ON in the example below. DANGER OF ELECTRIC SHOCK!All installation work must be carried out with the entire installa-tion in a de-energized state.Always follow the safety rules:• De-energize and isolate the system.• Verify isolation from the supply.• Secure against restart.• Short-circuit and ground.• Cover adjacent live parts.NOTICEChanges made to the dip switches' settings will take effect onlyafter the power supply is turned off and back on again.
