Upgrade the EnerVista software as outlined in this chapter.2. Input the IP address and subnet mask of the relay on the front panel under Settings > Product Setup >Communications > Network, and input the gateway address under Default IPv4 Route.3. Upgrade the firmware in the EnerVista software as outlined in this chapter, for example under Maintenance > UpdateFirmware.If you see error messages after the upgrade, disconnect power to the relay and shut down the software, then startboth again. If you see a flashing message about front panel communications trouble, check the connection of thegraphical front panel to the CPU module.4. In the EnerVista software, click the Device Setup button and refresh the order code for the device.5. Set the relay to Programmed mode under Settings > Product Setup > Installation.6. Update the EnerVista software to recognize the graphical front panel under Maintenance > Change Front Panel. Thissetting does not display for units already with a graphical front panel.11.11 Replace moduleThis section outlines how to replace a module.The relay, being modular in design, allows for the withdrawal and insertion of modules. Replace modules only with likemodules in their original factory configured slots.To replace a module:1. Open the enhanced front panel to the left once the thumb screw has been removed. This allows for easy access of themodules for withdrawal. The new wide-angle hinge assembly in the enhanced front panel opens completely andallows easy access to all modules in the L30.Figure 11-26: Modules inside relay with front cover open (enhanced front panel)Withdraw or insert a module only when control power has been removed from the unit, and besure to insert only the correct module type into a slot, else personal injury, damage to the unit orconnected equipment, or undesired operation can result.To avoid damage to the equipment, use proper electrostatic discharge protection (for example, astatic strap) when coming in contact with modules while the relay is energized.
