Decommissioning and Disposal

Where external components such as resistors or voltage dependent
resistors (VDRs) are used, these may present a risk of electric shock
or burns if touched.
Operation of computers and equipment connected to RT43x under
environmental conditions such as temperature and humidity that
exceed the conditions specified in their respective manuals can
cause malfunctioning or even irreversible damage to them or the
nearby installation.
There might be situations in which the unit is operating within its
environmental operational range, but the computers, equipment
connected to them or nearby equipment are operating outside their
operational range. That situation can cause malfunctioning and/or
irreversible damage to those devices. In that occasion the
communication to the Reason equipment might be compromised
but its operational and safety capacities will not be affected.
Do not insert or withdraw modules, PCBs or
expansion boards from the equipment while
energized, as this may result in damage to the
equipment. Hazardous live voltages would also be
exposed, endangering personnel.
Internal modules and assemblies can be heavy and may have sharp
edges. Take care when inserting or removing modules into or out of
the IED.
Before decommissioning, completely isolate the equipment power
supplies (both poles of any dc supply). The auxiliary supply input may
have capacitors in parallel, which may still be charged. To avoid
electric shock, discharge the capacitors using the external terminals
before decommissioning.
Avoid incineration or disposal to water courses. Dispose of the
equipment in a safe, responsible and environmentally friendly
manner, and if applicable, in accordance with country-specific
regulations.
