removed module. Furthermore, the replaced module should have the same software version. And
the replaced analog input module and power supply module should have the same ratings.
NOTICE!
After replacing modules, be sure to check that the same configuration is set as before
the replacement. If this is not the case, there is a danger of the unintended operation of
switchgear taking place or of protections not functioning correctly. Persons may also be
put in danger.
Units and modules may only be replaced while the supply is switched off and only by
appropriately trained and qualified personnel. Strictly observe the basic precautions to
guard against electrostatic discharge.
When handling a module, take anti-static measures such as wearing an earthed wrist
band and placing modules on an earthed conductive mat. Otherwise, many of the
electronic components could suffer damage. After replacing the main CPU module,
check the settings.
