Procedure complete
Replacing the System Controller
See also Application Note AN0145.
The SC300 system controller can be replaced without switching off the dc power system and
disconnecting the equipment it powers.
Before you start you will require:
•
A PC/Laptop with
DCTools*
connected to the system controller or a web browser*
connected to the system controller via an IP network.
*See Communications Options in the System Controller Operation Handbook.
•
A replacement SC300 system controller.
A new system controller is factory loaded with a 48V (nominal) default configuration file.
DCTools/Web can be used to modify the configuration file already loaded in a system controller.
Alternatively, the configuration can be converted using the “Generic Configuration” feature.
Refer to the SC300 Operation Handbook for more details.
•
A copy of the appropriate configuration file. Either:
•
use the configuration file saved from the existing system controller, or
•
contact your Eaton dc power system supplier to obtain a master configuration file to suit
the dc power system. This file will have to be customized for the site.
