Special conditions for safe use

Certificate number FM13ATEX0032X

The 'X' suffix to certificate number FM13ATEX0032X relates to the following special

conditions for safe use:

• The enclosure is non-conducting and, under certain extreme conditions, may generate an

ignition-capable level of electrostatic charges. The user shall ensure that the equipment is

not installed in a location where it may be subjected to external conditions (such as high-

pressure steam) which 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.

• Indoor use only. Additionally, the user shall ensure that the equipment is not installed in a

location where it is continuously exposed to ultraviolet light.

Certificate number FM14ATEX0027X

The 'X' suffix to certificate number FM14ATEX0027X relates to the following special

conditions for safe use:

• The enclosure is non-conducting and, under certain extreme conditions, may generate an

ignition-capable level of electrostatic charges. The user shall ensure that the equipment is

not installed in a location where it may be subjected to external conditions (such as high-

for example, acidic liquids or gases that may attack metals, or solvents that may affect

polymeric materials.
