Caution signs

10
Always connect the IED to protective earth, regardless of the operating conditions.
This also applies to special occasions such as bench testing, demonstrations and
off-site configuration. This is class 1 equipment that shall be earthed.
Never remove any screw from a powered IED or from a IED connected to powered
circuitry. Potentially lethal voltages and currents are present.
Take adequate measures to protect the eyes. Never look into the laser beam.
The IED with accessories should be mounted in a cubicle in a restricted access area
within a power station, substation or industrial or retail environment.
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 IED's operation. Be
careful and check regulations before making the change.
