Caution signs
IP1503-1 v1
GUID-5D1412B8-8F9D-4D39-B6D1-60FB35797FD0 v1
Whenever changes are made in the IED, measures should be taken
to avoid inadvertent tripping.
GUID-F2A7BD77-80FB-48F0-AAE5-BE73DE520CC2 v1
The IED contains components which are sensitive to electrostatic
discharge. ESD precautions shall always be observed prior to
touching components.
M2695-2 v2
Always transport PCBs (modules) using certified conductive bags.
M2696-2 v1
Do not connect live wires to the IED. Internal circuitry may be
damaged
M2697-2 v2
Always use a conductive wrist strap connected to protective earth
when replacing modules. Electrostatic discharge (ESD) may
damage the module and IED circuitry.
M2698-2 v2
Take care to avoid electrical shock during installation and
commissioning.
M2693-2 v1
Changing the active setting group will inevitably change the IEDs
operation. Be careful and check regulations before making the
change.
GUID-3BEE51C6-8793-4C89-B8A8-07D0FA6EE4CA v3
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.
