Installation 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.
Avoid touching the enclosure of the coupling capacitor REX061 unit and the shunt
resistor REX062 unit. The surface may be hot during normal operation. The
temperature can rise 50°C in REX061 and 65°C in REX062 above the ambient
temperature.
Observe the maximum allowed continuous current for the different current
transformer inputs of the IED. See technical data.
