Iecex Approval - E2S IS-mA1M Instruction Manual

IECEx Approval

The IS-mA1M Sounder has also been approved to the IECEx
scheme.
The installation requirements
approved to the IECEx scheme are the same as the
installation requirements for IS-mA1M sounders approved to
the ATEX directive.
Certificate No. IECEx SIR 06.0045X
Marking: Ex ia I Ma (-40ºC <= Ta <= +60ºC)
Standards: IEC 60079-0:2017
IEC 60079-11:2011
IEC 60079-26:2014-10
CONDITIONS OF CERTIFICATION (as stated on the IECEx
Certificate of Conformity IECEx SIR 06.0045X)

The equipment has an ingress protection rating of IP65.
However, if it has been supplied without cable entry
devices, then the user shall ensure that the devices that
are fitted will provide an ingress protection that is
appropriate to the environment in which it is installed i.e.
IP20 or better. If only one of the two cable entries are
used, then the unused entry 'knockout' shall be left intact
or fitted with a blanking device that ensures ingress
protection appropriate to the environment in which it is
installed i.e. IP20 or better

The total capacitance connected to Terminal + w.r.t. –
(i.e. the capacitance of the cable plus any other
capacitance) shall not exceed 83 nF.

The enclosure is non-conducting and may generate an
ignition-capable level of electrostatic charges under
certain extreme condition. The user should ensure that
the equipment is not installed in a location where it may
be subjected to external conditions that might cause a
build-up of electrostatic charges on non-conducting
surfaces, additionally, cleaning of the equipment should
be done only with a damp cloth.

The equipment shall only be supplied via Terminals +
w.r.t. Terminal – from a barrier having a maximum open
circuit voltage Uo that is ≤28 V and a maximum short
circuit current Io that is ≤93 mA, where Io is resistively
limited. The barrier shall be ATEX certified by a notified
body.
The IS-mA1 sounders are marked with the certification
requirements for the ATEX and IECEx and approvals.
