Caution signs

Whenever changes are made in the IED, measures should be taken
to avoid inadvertent tripping.
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 earth
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.

Note signs

Observe the maximum allowed continuous current for the different
current transformer inputs of the IED. See technical data.
