CENELEC/ATEX APPROVED FLOWMETERS

Warning.

• The instructions in this section apply only to systems supplied as suitable for Hazardous Area use,

these bear a permanently fixed CENELEC/ATEX label, BASEEFA 03ATEX0344, attached to the
Sensor. It does not apply to parts or spares supplied as non certified. This is particularly important
where replacement equipment is to be incorporated into existing installations or when ordering
spares. If in doubt contact ABB for advice before proceeding.

• It is essential that the equipment is installed and maintained in accordance with the appropriate

standards for electrical equipment  for  use  in  flammable  atmospheres. Any  deviation from the
specified installation or conditions of use, or unauthorised repairs or adjustments can invalidate
assurances given by the certification of the unit.

• The contents of this book must be thoroughly understood before proceeding with any installation,

maintenance, use or repair.

• Systems located in hazardous areas should only be installed and maintained by suitably trained

personnel.

• The ultimate responsibility for the safety of any installation lies with the installing user/contractor.
