2.1 About the application
2.1.1 General description
This document mainly includes general information (in point form) on how to upgrade a standard PPU-2 to a
PPU-3 system, including mounting instructions and wiring descriptions, parameter and general standard con-
versions. Upgrading of a GPU-2 to a GPU-3 is a similar setup. Contact DEIF support for more details.
The general purpose of this document is to help the user with the first steps of upgrading a standard paralle-
ling and protection unit system.
DEIF A/S always recommends to create a full backup parameter file before the old unit is powered down.
