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 terminal 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 communica-
tion modules, 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 con-
figuration can then be made. A conformity test of the secondary system has also to be
done. When the primary system has been energised a directionality check should be
made.
