Preface
Thank you very much for having purchased a dust- and water-proof intrinsic safety
explosion-proof structure electronic scale, FZ623Ex, FZ3202Ex, FZ6202Ex and FZ15001Ex.
This document describes important items to use the device safely in the explosive atmosphere.
Read this document carefully before use to correctly operate.
■ About the certified explosion-proof structure
This scale is an explosion-proof electronic scale that has been certified as an intrinsic
safety explosion-proof structure electric device. It has been confirmed that the device does
not explode due to the generation of electric sparks or temperature rise of a component not
only during normal operation but also during abnormal operation (failure period) even when
used in the atmosphere of explosive gas.

writes “it is possible.” When performing installation, operation, maintenance or
inspection of this product, not only observe what is written or indicated in this
document or on the product surface but also pay adequate consideration to safety
measures.
