General technical specifications
5.3 Use of subassemblies/modules in a Zone 2 hazardous area
Special conditions for KEMA 04 ATEX 1151X
Special conditions for the KEMA 04 ATEX 1151X is shown below:
● The connecting or disconnecting of live conductors or operation of device switches (for
example, for installation or servicing purposes) is only allowed when it has been ensured
that the area is not explosive.
Special conditions for KEMA -5 ATEX 1137X
Special conditions for the following are shown below:
● You must install subassemblies/modules in an adequate housing. This must comply with
the IP54 degree of protection (according to EN 60529) as a minimum. The environmental
conditions under which the equipment is installed must be taken into account. There must
be a manufacturer's declaration for zone 2 available for the housing (in accordance with
EN 60079-15).
● If a temperature of > 70° C is reached in the cable or at the cable entry of this housing
under operating conditions, or if a temperature of > 80° C can be reached at the junction
of the conductors under operating conditions, the temperature-related properties of the
cables must correspond to the temperatures actually measured.
● You must take steps to ensure that the rated voltage through transients cannot be
exceeded by more than 40%.
Risks in opening the housing
The housing can only be opened for a short time (for example, for visual diagnostics). If you
do this, do not operate any switches, remove or install any modules, or disconnect any
electrical cables (plug-in connections).
You can disregard this warning if you know that the atmosphere is not hazardous (in other
words, there is no risk of explosion).
Risks in disconnecting plug-in connections
Personal injury and property damage can occur.
There is a risk of injury or damage if you disconnect any plug-in connections in potentially
explosive environments while the ET 200S system is in operation.
Always de-energize the ET 200S system in potentially explosive environments before
disconnecting plug-in connections.
