Installation 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 IED's 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.
