RT411 Chapter 2 – Safety Information
RT411 16
Check voltage and current rating of external wiring, ensuring it is
appropriate for the application.
Peripheral Circuitry
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 equipment connected to RT41x 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.
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 may have sharp edges. Take care
when inserting or removing modules into or out of the IED.
