Commissioning manual
The IED contains components which are sensitive to electrostatic discharge. ESD
precautions shall always be observed prior to touching components.
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 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.
