Transformer protection RET650
Commissioning manual
Always use a conductive wrist strap connected to protective ground when
replacing modules. Electrostatic discharge (ESD) may damage the module and IED
circuitry.
Take care to avoid electrical shock during installation and commissioning.
Changing the active setting group will inevitably change the IEDs operation. Be
careful and check regulations before making the change.
Observe the maximum allowed continuous current for the different current
transformer inputs of the IED. See technical data.
