1. Switch the IED off and insert the new module.2. Switch the IED on, wait for it to start, and then perform a HW reconfig.3. Perform a license update in PCM600.The new module is now available in PCM600 and is ready to be configured.Removing a module from an IEDProcedure:1. Remove all existing configuration for the module in PCM, and write that configuration to theIED.2. Switch the IED off and remove the HW module.3. Switch the IED on, wait for it to start, and then perform a HW reconfig.4. Perform a license update in PCM 600.If any configuration that makes the module needed remains, then the HW reconfigwill not remove the module.The module will still be needed. An error indication for the module will appear, if themodule is physically removed from the IED and the IED is restarted with some partof the configuration still requiring the module.Moving a module in an IED from one position to anotherProcedure:1. Remove all existing configuration for the module in PCM, and write that configuration to theIED.2. Switch the IED off and move the HW module.3. Switch the IED on, wait for it to start, and then perform a HW reconfig.4. Perform a license update in PCM600.The new module is now available in PCM600 at the new position and is ready to be configured.14.3 Repair instruction IP8767-1 v1M11764-2 v2Never disconnect the secondary connection of a current transformer circuitwithout short-circuiting the transformer’s secondary winding. Operating a currenttransformer with the secondary winding open will cause a massive potential buildup that may damage the transformer and may cause injuries to humans.Never connect or disconnect a wire and/or a connector to or from a IED duringnormal service. Hazardous voltages and currents are present that may be lethal.Operation may be disrupted and IED and measuring circuitry may be damaged.1MRK 504 154-UUS B Section 14Troubleshooting237Commissioning manual
