2.4
Explosion protection according to ATEX and IECEx
●
The TRANSIC151LP is certified for a process-side operating range from 800 mbar(a) to
1400 mbar(a). Usage with deviating pressures voids the Ex certification.
●
The TRANSIC151LP must be operated within the specifications described in the Section
Technical Data,
. Operating the TRANSIC151LP outside
the specifications voids the Ex certification.
Operation in potentially explosive atmospheres
The TRANSIC151LP is suitable for the following zones
In accordance with ATEX (EN60079-10) and IECEx (IEC60079-10)
●
Gas:
– Measuring probe: Category 1G EPL Ga (Zone 0)
– Transmitter / voltage supply unit: Category 2G EPL Gb (Zone 1)
●
Dust
(alternative)
:
– Transmitter / voltage supply unit / measuring probe: Category 2D EPL Db (Zone 21)
The TRANSIC151LP may be used in zones in which either inflammable or explosive gases
in groups I, IIA and IIB or inflammable dust in groups IIIA, IIIB and IIIC are present.
Temperature class: Gas: T4 (max. surface temperature 135°C); dust: T85°C

▸
Do not remove, add or change any components in or on the device unless such
changes are officially allowed and specified by the manufacturer. Otherwise the
approval for use in potentially explosive atmospheres becomes void.
▸
Adhere to the prescribed maintenance intervals,
.
▸
The TRANSIC151LP may only be used in zones corresponding to the Ex identification
(see type plate) of the transmitter and the power supply unit. Check the
requirements of the installation location with the Ex certification of the device.
▸
The TRANSIC151LP may only be installed by persons trained in the standards used
(e.g., EN/IEC 60079-14).
▸
The TRANSIC151LP may not be modified. Any modification to the device voids the Ex
certification.
