<Certificate numbers>

IECEx PRE 20.0064 X

Presafe 20 ATEX 69725 X
* The “X” at the end of the certificate number indicates the following special operating conditions:
・
Do not attempt to repair explosion-proof joints.
・
Damage to the window plate due to strong impact may affect explosion-proof performance. The product is
subject to “Low (2J)” explosion-proof conditions, indicating risk of mechanical damage.
・
Avoid rubbing the nameplate area with a dry cloth during use, maintenance, or cleaning. Doing so may result
in a static charge buildup of up to 6 nF.
・
For information on the explosive-proof operating temperature range, refer to <Explosion-proof performance
data> in ‘2-4 Safety information’.
・
If attaching a lightning arrester to the SD-3, apply high-strength thread-locking compound to the mounting
screw.
・
The ATEX compliant models do not support the measuring functions specified in 1.5.5 of Annex II of the
ATEX directive. This directive provides guidelines on the performance of gas detectors and safety devices
and is based on the requirements of related EU harmonized standards.
・
The IECEx models do not support the measuring functions of EUT. These guidelines address the
performance of gas detectors and safety devices.
