Phasor measurement unit RES670
Commissioning manual
Always transport PCBs (modules) using certified conductive bags.
Do not connect live wires to the IED. Internal circuitry may be damaged
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 IED's 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.
