Overview
1 Commissioning and installation overview
The settings for each function must be calculated before the commissioning task can start. A
configuration, made in the configuration and programming tool, must also be available if the ter-
minal does not have a factory configuration downloaded.
The terminal is unpacked and visually checked. It is preferably mounted in a cubicle or on a wall.
The connection to the protection system has to be checked in order to verify that the installation
was successful.
The installation and commissioning task starts with configuring the digital communication mod-
ules, if included. The terminal can then be configured and set, which means that settings and a
configuration has to be applied if the terminal does not have a factory configuration downloaded.
Then the operation of each included function according to applied settings has to be verified by
secondary injection. A complete check of the configuration can then be made. A conformity test
of the secondary system has also to be done. When the primary system has been energised a di-
rectionality check should be made.
