4.3
Checking the power supply
Check that the auxiliary supply voltage remains within the permissible input voltage range under all
operating conditions. Check that the polarity is correct before energizing the IED.
4.4
Energizing the IED
4.4.1
Checking the IED operation
Check all connections to external circuitry to ensure correct installation, before energizing the IED and
carrying out the commissioning procedures.
Energize the power supply of the IED to pickup. Keep the DC power supply on until the Root menu or the
selected default screen is shown on the HMI before interrupting the DC power supply again. The
energization could be done in a number of ways, from energizing a whole cubicle with many IEDs to
energizing each single IED one by one.
If HW (i.e. I/O and/or communication boards etc.) have been changed (i.e. removed, replaced, or added),
the user should re-configure the IED by navigating in the local HMI menu to: Main menu/Configuration /
Reconfigure HW modules to activate the changed hardware modules in order to enable the self-
supervision function to detect possible hardware errors.
Check also the self-supervision function in Main menu/Diagnostics/IED status/General menu in local
HMI to verify that the IED operates properly.
Set the IED time if no time synchronization source is configured.
To ensure that the IED is according to the delivery and ordering specifications documents delivered
together with each IED, the user should also after start-up use the built in HMI to check the IED's:
•
Software version, Main menu /Diagnostics/IED status /Product identifiers.
•
Serial number, Main menu /Diagnostics/IED status /Product identifiers.
•
Installed modules and their ordering number, Main menu/Diagnostics /IED status/Installed HW .

Do not insert anything else to the female connector but the corresponding male
connector. Inserting anything else (such as a measurement probe) may damage the
female connector and prevent a proper electrical contact between the printed circuit
board and the external wiring connected to the screw terminal block.
Instead of the LHMI the Remote IED Access tool, RIA600, can be used and perform all
of the actions that a physical LHMI can.
Information about LHMI working procedures is also valid when the operation is
performed through RIA600. For more information on RIA600 operations, see manual
Remote HMI client RIA600 user guide (1MRK 511 619-UEN).
