Parameters apply to entire system inclusive of cables.
Each specified electrical parameter must be applied
individually and in combination. Do not exceed the
maximum values when applying the electrical parameters
individually or in combination.
Specific conditions of use
1
see Data Sheet DS/AWT210-EN) contains aluminium and is
considered to present a potential risk of ignition by impact
or friction. Care shall be taken into account during
installation and use to prevent impact or friction.
2
for areas subject to explosive dust atmospheres the painted
surface of the AWT210 may store electrostatic charge and
become a source of ignition in applications with a low
surface is relatively free of surface contamination such as
dirt, dust, or oil. Guidance on protection against the risk of
ignition due to electrostatic discharge can be found in IEC TS
60079-32-1. Cleaning of the painted surface shall only be
done in accordance with the manufacturer’s instructions
(see page 7).
3
for areas subject to explosive gas atmospheres the Lexan
enclosure AWT210 may store electrostatic charge and
become a source of ignition in applications with a low
relatively free of surface contamination such as dirt, dust, or
oil. Guidance on protection against the risk of ignition due to
electrostatic discharge can be found in IEC TS 60079-32-1.
Cleaning of the surface shall only be done in accordance with
the manufacturer’s instructions (see page 7).
4
the AWT210 shall not be used where UV light or radiation
may impinge on the enclosure or the window of the
enclosure.
