Procedure:
1. Remove all existing configuration for the module in PCM, and write that
configuration to the IED.
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.

Repair instruction
IP8767-1 v1
M11764-2 v3
Never disconnect the secondary connection of a current transformer
circuit without short-circuiting the transformer’s secondary
winding. Operating a current transformer with the secondary
winding open will cause a massive potential build up 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 during normal service. Hazardous voltages and currents are
present that may be lethal. Operation may be disrupted and IED and
measuring circuitry may be damaged.
M11764-10 v1
An alternative is to open the IED and send only the faulty circuit board to ABB for
repair. When a printed circuit board is sent to ABB, it must always be placed in a
metallic, ESD-proof, protection bag. The user can also purchase separate
replacement modules.
Strictly follow the company and country safety regulations.
M11766-4 v3
Most electronic components are sensitive to electrostatic discharge and latent
damage may occur. Please observe usual procedures for handling electronics and
also use an ESD wrist strap. A semi-conducting layer must be placed on the
workbench and connected to earth.
Disassemble and reassemble the IED accordingly:
1. Switch off the dc supply.
2. Short-circuit the current transformers and disconnect all current and voltage
connections from the IED.
3. Disconnect all signal wires by removing the female connectors.
4. Disconnect the optical fibers.
