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 RT430 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 RT430 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 recording, operational and safety capacities will not be affected.
4.7 Upgrading/Servicing
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.
5 Decommissioning and Disposal
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.
6 Standards Compliance
Compliance with the European Commission Directive on EMC and LVD is demonstrated using a Technical
File.
